Opis:
The study analysed the causes of the annual variation of tree−ring widths of silver fir and white fir. The partial populations of both fir species has been growing for over 100 years in Rzepin (western Poland) in a fresh broadleaved forest site. We assumed that the year−to−year changes of the size of radial increment presents sensitivity of trees to local climate factor. The period from 1931 to 2015 was analysed. We found that the silver and white firs had high homogeneity of radial growth responses and sensitivity to year−to−year changes of weather conditions. Warm November of the previous year, short winter and high air temperature in August had positive influence on the size of their radial increment. Moreover, precipitation in February, April and July of the year of tree−ring formation contributed to wider tree−ring. The white fir was highly resistant to winter frost in contrast to the silver fir. In addition, this fir species preferred cold springs. Furthermore, the silver fir suffered from overabundant precipitation in August. The climate conditions of western lowland part of Poland were not a limiting factor for growth of both species because the studied populations achieved the highest site index class.

Opis:
Abies fraseri (FF) is a North American conifer which is crucial for growers of Christmas trees. This species suffers 100% mortality after infection of root rot caused by Phytophthora cinnamomi. The hybrid material A. cilicica × A. cephalonica (CZ) and A. koreana × (A. cilicica × A. cephalonica) was utilized as mother trees for applications of Abies fraseri pollen. In addition to resistance to fungal disease, a long-term monitoring of growth of young seedlings along with the impact of artificial crossing on morphology of the progeny is covered. Except for increased resistance, some offspring has also exhibited a remarkable heterosis effect at younger age and different growth habit and different shape of their needles. All this may offer in the future a wide range of applications, both for crops under strong anthropogenic pressure with changing climatic conditions and for crops grown for production of Christmas trees and outstanding ornamental cultivars. Annual crossing success was determined in present study using X-ray imaging. The most successful combinations in 2012 were those of CZ1 × FF25 and CZ1 × FF76 with 7% of full seeds, followed by CZ2 × FF25 with 6% and CZ2 × FF31 with 4% of the full seeds. The evaluation of young seedlings from control crossing in 2007 highlighted significant accented height growth of complicated hybrid (A. koreana × (A. cilicica × A. cephalonica)) × FF PC. Morphology of needles showed variability in their length as compared with the needle width which was found to be less appropriate characteristic for distinguishing between different combinations.
Abies fraseri (FF) jest północno-amerykańskim iglakiem ważnym z punktu widzenia hodowców choinek świątecznych. Gatunek ten wykazuje 100% śmiertelność po porażeniu zgorzelą korzenia spowodowaną przez Phytophthora cinnamomi. Materiał hybrydowy A. cilicica × A. cephalonica (CZ) oraz A. koreana × (A. cilicica × A. cephalonica) został wykorzystany jako drzewa matczyne do aplikacji pyłku Abies fraseri. Poza odpornością na chorobę od grzybową, badania dotyczyły długoterminowego monitorowania wzrostu młodych siewek oraz wpływu sztucznego krzyżowania na morfologię potomstwa. Oprócz zwiększonej odporności, niektóre młode rośliny wykazały znaczny efekt heterozy, różny wzrost i różny kształt igieł. Wszystko to może w przyszłości dać wiele różnorodnych zastosowań, zarówno w przypadku roślin pod silną presją antropogeniczną przy zmiennych warunkach klimatycznych jak i dla roślin hodowanych do produkcji choinek świątecznych oraz na wybitne odmiany ozdobne. Powodzenie corocznego krzyżowania określono w niniejszym badaniu pryz użyciu promieniowania rentgenowskiego. Najbardziej udanymi kombinacjami w 2012 r. były CZ1 × FF25 i CZ1 × FF76 z 7% pełnych nasion, a następnie CZ2 × FF25 z 6% i CZ2 × FF31 z 4% pełnych nasion. Ocena młodych sadzonek pochodzących z kontrolnego krzyżowania w 2007 r. wskazała na istotnie zaznaczony wzrost złożonej hybrydy (A. koreana × (A. cilicica × A. cephalonica)) × FF PC. Morfologia igieł wykazała różnorodność ich długości w porównaniu z szerokością igieł, która była mniej istotną cechą do odróżnienia kombinacji.

Opis:
Height-diameter models define the general relationship between the tree height and diameter at each growth stage of the forest stand. This paper presents generalized height-diameter models for mixed-species forest stands consisting of Norway spruce (Picea abies Karst.), Silver fir (Abies alba L.), and European beech (Fagus sylvatica L.) from Slovakia. The models were derived using two growth functions from the exponential family: the two-parameter Michailoff and three-parameter Korf functions. Generalized height-diameter functions must normally be constrained to pass through the mean stand diameter and height, and then the final growth model has only one or two parameters to be estimated. These “free” parameters are then expressed over the quadratic mean diameter, height and stand age and the final mathematical form of the model is obtained. The study material included 50 long-term experimental plots located in the Western Carpathians. The plots were established 40–50 years ago and have been repeatedly measured at 5 to 10-year intervals. The dataset includes 7,950 height measurements of spruce, 21,661 of fir and 5,794 of beech. As many as 9 regression models were derived for each species. Although the “goodness of fit” of all models showed that they were generally well suited for the data, the best results were obtained for silver fir. The coefficient of determination ranged from 0.946 to 0.948, RMSE (m) was in the interval 1.94–1.97 and the bias (m) was –0.031 to 0.063. Although slightly imprecise parameter estimation was established for spruce, the estimations of the regression parameters obtained for beech were quite less precise. The coefficient of determination for beech was 0.854–0.860, RMSE (m) 2.67–2.72, and the bias (m) ranged from –0.144 to –0.056. The majority of models using Korf’s formula produced slightly better estimations than Michailoff’s, and it proved immaterial which estimated parameter was fixed and which parameters were free.

Opis:
The aim of the study was to evaluate the sensitivity of silver fir (Abies alba Mill.) from the Rudnik Forest District on the selected meteorological elements and to develop a chronology of local tree-ring width and the annual sensitivity. Based on the analysis, the site chronology of silver fir was developed and the strength of the relationship between the climate components and the width of annual rings was calculated. In addition, we examined the degree of homogeneity of short-term incremental response, rated the representativeness of the chronology and climate signal strength. Having analysed the indicator years, namely 1932–2013, we concluded that the growth of firs was positively influenced mainly by air temperature in winter, and to a lesser extent, by precipitation in spring and summer. The main factors that limit its growth are cold winters, cool and low rainfall summers, and rainy springs.

Opis:
The research was conducted in beech−fir and beech stands in the territory of the Babiogórski and Ojcowski national parks. The obtained results showed that the density of seedlings after the autumn seed fall was small. The seed fraction from which seedlings emerged did not exceed 8%. In the Babiogórski National Park, no spatial relationship was found between seed and seedling abundance. However, such relationship was found in beech and sycamore in the Ojcowski National Park during one season. This was associated with a lower density of seed predating rodents in the forests around Ojców than on the Babia Góra and the specificity of the environmental providing a wide variety of living conditions for small mammals.

Opis:
In Poland, the majority of silver fir stands is characterised by a single−layer stand structure. The current silvicultural activities aim at obtaining multilayer stands, which requires a clearer definition of the structure, and more precisely, a better knowledge of the pattern of diameters at breast height (DBH) distribution. The aim of the research was to develop a pattern of DBH distribution of trees in a multilayer silver fir stand in the Świętokrzyskie Mountains (central Poland) using the BDq method, through the mathematical determination of function parameters, including the productive capacity of the habitat. The application of this pattern will allow the selection of the management methods aimed to obtain and then maintain model stands with a different layer structure. The research was based on the empirical material collected in 56 stands that were characterized by both a single− and a multi−layered structure. They grew in coniferous forest habitats, mostly in the upland mixed coniferous forest, upland mixed deciduous forest and upland deciduous forest or mountain forest. One big (up to 1 ha) or 3−5 smaller (0.04 ha) sample plots were established in each stand in which diameters at breast height of all trees and heights of usually 25 trees, selected from the entire range of diameters, were measured. These were used to determine the height growth curve equation coefficients and then the height of each tree. For each stand the basal area was calculated and a graph for DBH distribution was prepared. Site index was established using the original empirical equation. In order to develop a model for multilayer fir stands, individual parameters of the equation 5, such as the basal area (B), the target diameter at breast height (D) and the coefficient q were to be determined using the BDq method. Taking into consideration only stands with one−tailed DBH, individual parameters of the function were found to be associated with site index. Empirical equations were developed for the determination of B and D, and, based on the DBH distribution graphs, coefficient q associated with site index was also calculated (tab.). The developed DBH distribution pattern is a mathematical description of the target fir stand. When the value of stand parameters approaches those of the model stand, it should be managed using the shelterwood cutting system, which results from the spatial variation in the stand height structure, and consequently from the need for different silvicultural treatments in different stand fragments.

Opis:
In March 2017, in the eastern part of the Tatra National Park in Poland, large windthrowns affected the passively and actively protected Norway spruce Picea abies stands. In early 2018, a set of 12 small research plots (20 trees on each plot) was established in the Norway spruce stands next to the windblown area – 6 in the stands under active nature protection (broken and fallen trees processed in 2017), and 6 in the stands under passive nature protection (trees left on the ground). Living trees on the plots were regularly checked during the growing season in order to identify and register the spruces infested by Ips typographus, which were dissected in 2 or 4 halfmeter sections. 155 spruces (64%) infested by I. typographus were recorded on all 12 plots: 118 out of 120 (98%) in passive and 37 out of 120 trees (31%) in active protection. Mean infestation density calculated on 128 samples from 47 trees was higher under passive than under active protection (1.23 and 0.92 mating chamber per 1 dm2, respectively). Among 1709 gallery systems, those with 2 maternal galleries prevailed (63.0%); the mean share of females was higher in passive than in active protection zone (63.1 and 59.6% respectively). The mean number of progeny per one female was higher in active than in passive protection zone (20.23 and 19.12 respectively). I. typographus attack on standing trees had lower intensity in the stands previously subjected to the processing and removal of fallen and broken trees, which indicates positive effect of implemented active protection procedures. The parameters describing I. typographus population on attacked trees, as well as low activity of natural enemies, demonstrate its reproduction potential and resulting high risk of a new outbreak, according to the pattern known earlier from the other areas in Poland and Europe.

Opis:
Origin of Norway spruce in the territory of Skrwilno Forest District was studied with the use of mitochondrial mt−D02 region inherited through maternal line. The former suppositions of Jedliński, who claimed that the origin of spruce in this territory was natural, have been confirmed. Concurrently, it has been established that in the majority of tree stands subject to our study there occurs spruce of Carpathian origin. The obtained results together with the palinological data indicate that the northern border of spruce range in Poland runs right through the territory of Skrwilno Forest District and not about 100 km to the south from this place as has been claimed so far.

Opis:
The genetic structure of Norway spruce [Picea abies (L.) Karst] of the Istebna race was studied in two populations from the Carpathian seed stands in the Malinka and Czarne Forestries. The recent provenance test results have shown a high quality of both populations. The results were compared with the genetic variation parameters calculated for the selected seed stand from the Bukowiec Forestry (compartment 149h), whose genetic structure in the progeny test for this species is considered a national standard. Five enzyme systems were analysed. The results show that the mean number of alleles per locus and the heterozygosity observed in the analysed populations are greater than those reported in the literature for other natural Norway spruce populations from the Carpathians. The heterozygosity level of the studied seed stands was higher than of the selective population of the Istebna spruce plus trees and the level of genetic diversity was similar to that of the Bukowiec seed stands. Thus, it can be concluded that the analysed seed stands from Czarne and Malinka, compartment 91h can be used as a supplementary seed base. However, at the individual partial population level, the Bukowiec spruce population, compartment 149h is considered to be of the highest value.

Opis:
Geomorphological events are very important disturbance factors for cliff forests and forests located on steep mountain slopes. In this study we present dendrochronological reconstruction of two types of disturbances which affect subalpine forest growing in such extreme habitats in Roztoka Valley in the Tatra Mountains: landslide and rockfalls. We determine the years of death of trees found in landslide area on Czuba Roztocka which indicate the year of 1997 as the time of this event, probably related to heavy midsummer rainfall in this year. Scars on trees growing at the base of Orle Ściany cliff allowed determining the rockfall events. We found that scars, even in neighbour trees were formed in different years between 1940 and 2004. It means that they were formed rather by separate stones which fell from the cliff sporadically then a large scale fall of debris at the same time. This may suggest that rockfalls in cliffs of Orle Ściany were limited to single rocks which fell successively when erosion process separated them from the bedrock. Dendrochronology seems to be an effective method which enables long term reconstruction of gemorphological processes in the High Tatras.

Opis:
Tree stumps provide habitat for insect assemblages, which are influenced by various factors. Among these factors, physical and chemical changes of the stumps, fungi developing in the dead wood and stump size are most often reported. However there is limited information about the abundance of insects in stumps that are located on mountains where there are different microclimatic conditions. The studies pointed at the determination whether the location of Picea abies stumps in mountains at different altitudes above sea level and on mountainsides with different sun exposure has an impact on the frequency of insects colonising them. The study was carried out in the Eastern Sudety Mountains situated in south-western Poland. The stumps were in clearcuts located at the altitudes 600–700 m and 900–1000 m above sea level and on southern and northern mountainsides. The insects were collected from 0.05 m2 of bark from each stump and identified to the family, order or species level. The numbers of insects in the stumps were modelled with the use of the Poisson distribution or the negative binomial distribution and the generalised linear models. Picea abies stumps were colonised by insects from 16 families in 3 orders (Coleoptera, Diptera, Hymenoptera) in which the Coleoptera was most frequently represented by the families Cerambycidae, Curculionidae (with the sub-family Scolytinae). In the stumps located at the elevation of 900–1000 m there were 28% more insects than in the stumps at 600–700 m. The stumps located on mountainsides with northern exposure were colonised more abundantly by Cerambycidae. Numbers of Curculionidae in the stumps were affected by altitude. Most Curculionidae were found in the stumps located at the elevation 900–1000 m above sea level. The interaction of altitude and mountainside exposure showed more insects in the stumps at higher altitude, regardless of the mountainside exposure. The results showed that the total number of insects in the stumps was influenced by their location in mountains.

The paper deals with the research of the influence of thermal modification temperature of spruce wood on the electric energy consumption of its face milling. Samples of spruce wood heat treated at temperatures of 160, 180, 200 and 220°C were milled at the cutting speed of 20, 40 and 60 m.s-1, the feed rate of 6, 10 and 15 m.min-1, the rake angle of 15° with the depth of the cut of 1 mm. The energy consumption was evaluated from the cutting power, which was based on the difference during milling and idle cycle. The analysis of variance showed a decrease in cutting power with an increasing temperature of thermal modification. The average cutting power value is 137.7 W at the native sample and 80.8 W at the sample treated at 220°C. The Duncan’s test of statistical significance has shown that the thermal modification has a statistically significant effect on the cutting power values.

Opis:
The effect of drought stress on regular cambium activity and wood formation in stems of two different clones of Norway spruce (Picea abies (L.) Karst.) was investigated. Tissue samples were taken during the growing season from May to September 2010. Artificial drought stress, induced by long-term sheltering of the soil, was significantly manifested in clone 15. In the stressed individual, the period of cambium activity was shorter, the total number of formed cells was lower and the resulting tree ring was narrower. The number of cells in the phases of postcambial growth and secondary cell wall formation was significantly lower in comparison to the control tree. The tracheid lignification process was slower in the tree stressed by water deficit and the first mature tracheids were observed later. On the other hand, in clone 18 probably genetic dispositions played an important role as no considerable deviations in the cambium activity and new wood cells production were observed. Fitting xylem increments to the Gompertz function showed that the period of the most intensive cell formation was at the turn of June and July and the maximum daily production of new cells was higher in non-stressed individuals than in the stressed ones. The results of the experiment lead us to the conclusion that drought stress can significantly affect the cambium activity of some clones, the differentiation process of anatomical elements, and thus also the resulting tree ring width.

Opis:
The occurrence of silver fir (Abies alba Mill.) outside its natural distribution limits in the Baltic and Wielkopolsko−Pomorska Natual−Forest Regions depends mainly on anthropogenic factors and climatic conditions: annual precipitation sum and air temperature amplitudes. Dispersed stations in north−western and western Poland may indicate the expansion of its natural range possibly as a result of current climatic changes. The condition of mature stands and natural regeneration in the examined sites were good. For efficient silvicultural management of fir outside its natural range it is advisable to apply the cutting system with longer regeneration period and effectively protect the existing natural regeneration.

Opis:
The study assesses the damage to silver fir from the canopy layer in the stands of the Świętokrzyskie Mountains (central Poland) using three methods. The suitability of these methods was also analysed by calculating the correlation between increment of the diameter at breast height (DBH) and the level of damage. In total we investigated 240 trees. The first analysed method involves tree defoliation. The mean defoliation of sample accounts for 47.8%, while majority of the trees were found to be within 2nd damage class (fig. 1). Absolute and relative DBH increment does not correlate with tree defoliation strongly (tab.). The next method is based on the assessment of the average tree damage index W that takes into account defoliation, top condition and vitality. In general, analysed trees were found to have reduced height growth and both branching in the top (fig. 2) and central (fig. 3) section of the crown. Inclusion of the secondary crown in the assessment of tree damage resulted in an increase in the vitality of the whole crown (fig. 3). The assessment of damage based on index W showed that largest proportion of trees was within moderate damage and the value of the damage index was lower than in method based exclusively on defoliation. The last method (morphological−incremental) combines the method based on damage index W with DBH increment (index Wz, formula 3). In the period 1971−1985, most of the fir trees reacted negatively to the environment changes (growth reduction), while the proportion of trees with positive responses decreased. In the period 1976−2000, the proportion of trees with negative response decreased, while the proportion of firs with positive and neutral responses increased (fig. 5). The period 2001−2015 faced the dominance of trees showing neutral growth responses, the proportion of trees with positive responses was fairly high, while the proportion of trees with negative responses was the smallest. The highest value of the correlation coefficient (r=–0.661) was found for the correlation between the relative 10−years DBH growth and damage index Wz2(tab.). Of the three discussed damage assessment methods, this method is therefore considered the most accurate.

Opis:
Actual status of mountain forests especialy, of Norway spruce (Picea abies Karst. (L)) stands is a result of combined action between forest management measures and biotic and abiotic risk factors. In this context, tree growth dynamics is a result of multifactor interaction (competition, disturbance, management practice, climate etc.). Wind damage affect the stand structure and normal ecosystem functions including the relationship between individual tree growth and competition processes. Though, it is recorded a diminishing of productive capacity for affected stands as well as a significant diameter increment for remaining standing trees. The correlation between tree growth (cumulate basal area increment in the last 10 years) and competition (Hegyi and Schutz competition indices) was analysed in stands with different windfall intensity. No relationship between tree growth and competition was observed in highly affected stands. Schutz competition index explains better individual tree growth comparing with Hegyi index in low or no-affected stand by windthrow. The variability of the basal area increment (lnΔɡ10), explained by competition indices, is rather low (<2%) in the stand that had been highly affected by windfall, regardless of the selected competition index. Thus, significant reduction of the stand density related to number of trees (low density), as a consequence of high intensity windfalls, crown competition has a very small influence on the basal area increment comparing with situations met in low (high density) and moderate (medium density) affected stands.

The origin of the Norway spruce in the Kartuzy Forest District was verified using the maternally inherited mitochondrial DNA marker mt15−D02 that shows distinct geographical distribution in Europe. We analyzed 462 trees from 26 populations. The majority of trees were of Alpine origin and they were present in all populations at a frequency of 6−90% (mean 59%). About 30% of trees were of the Carpathian origin and the least abundant (11%) were trees of north−eastern origin. The trees carrying north−eastern type of the mitochondial DNA marker were found only in 13 populations, but at a very different frequency (from 5 to 88%). The possibility of natural origin of Norway spruce in the area of Kartuzy Forest District was shortly discussed.

The article demonstrates the results of the research studies related to the air polluted with heavy metals in the area of Swietokrzyski National Park. The two-year-old needles of Abies alba (Mill) were used as the bioindicator with the intention of carrying out the research. The studies were conducted in the autumn of 2012. The results showed the spatial variability of concentrations in the range of the analysed metal deposition patterns in the needles of Abies alba (Mill). The average content of the analysed elements seemed to be the highest in the case of zinc (26.6 mg·kg–1 d.m.), strontium (6.5 mg·kg–1 d.m.) and nickel (1.6 mg·kg–1 d.m.). The research studies revealed that the significant role in determining the content of heavy metals in the two-year-old needles was played by the communication. The highest values were recorded at the research sites situated in the immediate neighbourhood of the voivodeship roads. It was also confirmed that the content of metals was influenced by the so-called low emission from the household and welfare sector together with the remote imission.

The plant material was collected on 34 individuals growing in the Dendrological Garden of Poznań University of Life Sciences (52°25'32,95" N 16°53'39,83" E) and Botanical Garden of Adam Mickiewicz University in Poznań (52°25'11,70" N 16°52'55,07" E). The species for this study originated from Europe, Asia Minor, central and eastern Asia and North America and included: Abies alba, Abies cephalonica, Abies cilicica, Abies equi−trojani, Abies sibirica, Abies koreana, Abies pinsapo, Abies ×insignis, Abies bornmulleriana, Abies homolepsis, Abies holophylla, Abies grandis, Abies concolor, Abies concolor var. violacea, Abies concolor var. lowiana, Abies nordmanniana, Abies ×arnoldiana, Abies nephrolepis and Abies balsamea. The aim of this study was to define the species haplotypes (the length of allele) on the basis of nad5−4 mitochondrial DNA marker detected by capillary electrophoresis. This marker has been suggested as an easy−to−use tool to distinguish species of the Abies genus and it could be species−specific. Seven different haplotypes were identified. The first one appears in the species from Europe, Asia and North America. The second one was detected in firs from Europe and Asia Minor. A. cephalonica and A. sibirica were identified by the third haplotype, which occurs also in A. alba from the Balkan region. The fourth haplotype is characteristic for species from Asia and North America. The fifth and sixth haplotypes were identified in A. pinsapo and A. numidica. The seventh haplotype was detected only in A. holophylla. Applied marker is a very useful for verification of fir species especially allopatric species, less for parapatric ones. This marker is more helpful to exclude the species than to precisely identify them.

Opis:
The aim of the paper was to determine influence of traffic density on heavy metal concentrations (Cd, Cr, Cu, Ni, Pb, Zn) in two years needles of spruce Picea abies L. along the roads of various traffic density located in the Podhale region, Southern Poland. The samples of Picea abies L. were collected along two roads: heavily frequented main road no. 95 Kraków - Zakopane between Chabówka and Nowy Targ and a district road of low traffic density no. 1644 Łopuszna - Dursztyn, between villages Łopuszna and Nowa Biała. The samples were collected along five transects: three at the road no. 95 and two at the road no. 1644 at the following distances from the road: 5 m, 10 m, 50 m and 100 m. Generally, metal concentrations descended according to the increasing distances from the road. The highest concentrations were stated in case of Cu, Ni and Pb at the distance 5 meters from the road Chabówka - Nowy Targ (10,1 ± 1,3 µg Cu/g; 2,9 ± 0,2 µg Ni/g and 2,4 ± 0,6 µg Pb/g), and the lowest concentrations with exception of Cd were stated for both mentioned roads at the distance 100 meters. Traffic density influenced heavy metal concentrations in spruce Picea abies L. The differences in metal concentrations along two roads were presented by concentration coefficients, calculated as quotient of metal concentrations at the roads of various traffic density. The highest concentration coefficients at the distance of 5 m were stated for: Ni (2.6); Pb (2.4) and Cu (1.7) and the lowest for Cd (0.5), Cr (0.9) and Zn (0.8).
W artykule przedstawiono wpływ natężenia ruchu samochodowego na zawartość metali ciężkich (Cd, Cr, Cu, Ni, Pb, Zn) w świerku pospolitym Picea abies L. Próbki świerka pospolitego (dwuletnie igły) zostały pobrane wzdłuż dwóch dróg: o wysokim natężeniu ruchu (Kraków – Zakopane na odcinku Chabówka – Nowy Targ) oraz o niskim natężeniu ruchu (Łopuszna – Dursztyn na odcinku Łopuszna – Nowa Biała). Transekty, w których pobrano próbki, usytuowane były prostopadle do osi jezdni, w czterech odległościach od drogi (5 m, 10 m, 50 m i 100 m). Zauważono prawidłowość, że w miarę oddalania się od drogi koncentracje metali ciężkich, z wyjątkiem Cd, zmniejszały się. Stwierdzono również, że natężenie ruchu samochodowego miało wpływ na zawartość metali w igłach świerka. Różnice w zawartości metali wyrażone za pomocą współczynników koncentracji, w odległości 5 m od drogi, osiągały najwyższe wartości w przypadku niklu (2,6) oraz ołowiu (2,4) i miedzi (1,7).

Opis:
The paper presents research results on the extent and rate of horizontal and vertical infection spread process inside fir stems as a result of bark stripping by game and factors determining infection development. The material collected in the stands of the Forest Experimental Station in Krynica (Beskid Sądecki) allows to state that the infection affected exclusively those tree rings which had been formed before wounding. The radial spread of the infection was on average 17% of the cross−sectional area of the stem at a height of the wound centre, and the axial spread was maximally up to 3 m above the ground level. The average rate of horizontal spread of decay inward the stem was 2% of the cross−sectional area per year and that of the movement of decay fungi up and down the tree – 4.7 cm per year. The most important factors affecting infection development inside the stem were: the per cent of wound closure, age and wound size, as well as tree dimensions at the time of bark stripping. The higher degree of decay significantly lowered the index value of the growth predisposition and vitality of damaged young firs.

The aim of this study was to investigate differences in radial increment reaction of Norway spruces from the Beskidy Zachodnie Mountains (S Poland). Spruce stands were located at different altitudes and slope aspect. Two altitudinal zones were distinguished by a separating altitude of 900 m a.s.l. The dendrochronological belts, consistent in terms of radial increment, amount to 200−250 m in the lower zone, and narrow down to ca. 100 m in the upper one. Factor differentiating radial increment of spruces at various altitudes was temperature in September of previous year as well as precipitation in March and June of current year.

Opis:
The strength and temporal rigidity of climate signals are important characteristics of proxy data used to reconstruct climate variability over pre-instrumental periods. Here, we assess the performance of different tree-ring proxies, including ring width, maximum latewood density, δ13C, and δ18O, during exceptional cold (1800–1850) and warm periods (1946–2000). The analysis was conducted at a spruce (Picea abies) timberline site in the Swiss Alps in proximity to long homogenized instrumental records to support calibration tests against early temperature and precipitation data. In this cold environment, tree-ring width, maximum latewood density, and δ18O are mainly controlled by temperature variations. δ13C is influenced by various factors including temperature, precipitation, sunshine, and relative humidity. When comparing the response patterns during cold and warm periods, ring width and maximum latewood density revealed temporally stable temperature signals. In contrast, the association between the stable isotopes and climate changed considerably between the early 19th and late 20th centuries. The temperature signal in δ18O was stronger during the recent warm period, whereas the opposite is true for δ13C. In δ13C, the temperature signal weakened from the early 19th to the late 20th centuries, but an (inverse) precipitation signal evolved indicating that soil moisture conditions additionally limited recent carbon isotope ratios. An attempt to combine the tree-ring proxies in a multiple regression model did not substantially improve the strength of the dominating temperature signal retained in the latewood density data as this proxy already explained a significant fraction of summer temperature variability. Our findings underscore the importance of split calibration/verification approaches including cold and warm periods, and challenge transfer models based on only late 20th century observational data.

Opis:
In 2004, abundant flowering of Norway spruce (Picea abies (L.) Karst.) was observed in two second- generation seed orchards: (1) ‘Outbreeding’, promoting crossing between clones of five geographically distant populations; and (2) ‘Kolonowskie’, restoring a population whose offspring exists only in an international experiment (IUFRO 1964/1968). In bothseed orchards, female strobili were produced by 91.3% and 91.7% of clones, represented by 64.1% and 55.5% of grafts, respectively, and statistically significant differences between clones were found in the number of mature cones. In the case of the seed orchard ‘Outbreeding’, the number of mature cones in individual clones was significantly correlated with latitude of the origin of maternal populations (r = 0.8826, p = 0.0470). The majority (95%) of cones in seed orchards ‘Outbreeding’ and ‘Kolonowskie’ were produced by only 28.2% and 38.5% of all clones, and 21.4% and 25.7% of all grafts, respectively. These data attest to a disparity between the level of genetic diversity in seed orchard progeny resulting from the observed numbers of cone-bearing clones and grafts and the genetic diversity expected from the actual participation of clones and grafts in seed orchard composition. The estimated seed production per 1 ha of seed orchard area in 2004 reached 21.05 kg for ‘Outbreeding’ and 21.72 kg for ‘Kolonowskie’.

Opis:
Progeny of four adult silver firs, which were an admixture in Norway spruce (Picea abies) stand was, analyzed. The study was done in lower mountain zone of the Karkonosze (Giant Mts.) National Park (SW Poland). The seedlings occurred in two clumps related to the position of adult trees, whereas spatial pattern of the seedlings inside each clump was random. The seedlings were spaced mainly in distances 5–25 from the nearest adult tree. The maximal distance was up to 50 m. Most seedlings were established in accordance with main wind directions. Also, in these directions seedlings were more distant from adult trees than in other directions. The seedlings grew in better light environment (12% of PPFD) than average (9,6% PPFD). This effect was statistically significant. The height increment of the seedlings was low and was not correlated with light conditions. Similarly, there was not any correlation between the apical dominance ratio and light. The lack of this correspondence we attributed to browsing. The silver fir seedlings were significantly underrepresented in patches of Vaccinium myrtillus, on raw needles, under crown of adult trees and in concave micro-relief form. The underrepresentation in the places covered by canopy and in patches of bilberry we related to the indirect effect of continuous browsing, which leads to higher seedlings mortality in more shaded places and sites of stronger competition between forest floor vegetation and silver fir seedlings.

In this study the genetic structure of Istebna and Tarnawa plus trees was studied and polymorphism of twenty four provenances of spruce tested in a IPTNS−IUFRO 1964/68 site in Krynica representing selected regions of the species occurrence was analyzed. The genetic diversity was estimated with seven isoenzyme systems encoded in eleven loci. The highest genetic polymorphism was shown by plus trees of the Istebna and Tarnawa race and the lowest by spruce from IUFRO experiment. There was a statistically significant effect of origin on the mean number of alleles per locus. The origin of the analyzed trees had no effect on other parameters of genetic variability: the effective number of alleles per locus, observed and expected heterozygosity and Wright index.

Opis:
The objective of this study was to determine the influence of the age of parent tree stand on selected physical properties of Norway spruce seeds to improve the efficiency of seed separation processes. Seeds were harvested in a forest complex located in the seed zone No. 202, in the municipality of Kruklanki in the Borki Forest District (N Poland) during mast years (1999, 2004, 2007 and 2012). The experimental material comprised of Norway spruce seeds from three differently aged tree stands (86, 119 and 129 years old in the first harvest year). The following measurements were performed for each seed: terminal velocity – with a pneumatic classifier; length and width – with a laboratory microscope; thickness – with a thickness gauge; angle of external friction – on an inclined plane, in two positions on a steel friction plate, and mass – with a laboratory scale. The results were used to calculate the arithmetic and geometric mean diameters, aspect ratio, sphericity index and density of seeds. The values of the analyzed properties were compared with ANOVA for factorial designs and linear correlation analysis. The results of the study indicate that Norway spruce seeds obtained from cones harvested in 2012 are characterized by the highest thickness and, consequently, by the highest values of the aspect ratio and sphericity index. The age of parent trees significantly influences the majority of physical properties of seeds. However, the patterns of observed changes are difficult to interpret due to the impact of weather conditions and the genetic potential of parent trees, which perform differently in response to changing climate and geomorphological conditions. Over the analyzed 13−year period a gradual increase was noted in the width, geometric mean diameter, aspect ratio and sphericity index of seeds, whereas the length and density of seeds decreased. Therefore, Norway spruce seeds should be separated mostly with the use of mesh screens with longitudinal openings, pneumatic separators and graders. The use of those devices, separately or in combination, for sorting Norway spruce seeds into mass fractions could contribute to more uniform seedling emergence when every seed fraction is sown separately.

Opis:
Pheromone traps are used for monitoring I. typographus populations in Norway spruce stands of the Tatra National Park (TPN) in Poland. The presented study is based on the set of pheromone traps of precisely known location (23) located in the whole area of the TPN and operated continuously in 2010–2019. The data on the captures of beetles were compared with two kinds of data concerning the mortality: the area covered by standing dead trees (airborne photographs) in the no-intervention zone, and the volume of trees infested by bark beetles processed in the active protection zone. No relationship was found between the mean numbers of beetles captured yearly in all pheromone traps in the whole TPN area and the volume of infested trees removed from the stands in the active protection zone. The captures in the two selected study areas were correlated with the area of spots with dead trees in the 500 m circle around the traps, however, this correlation is not statistically significant. There is no relation of captures to the volume of processed infested trees. The captures decreased in the growing seasons after the wind damage, and increased markedly after the drought started in 2015. The results of pheromone trapping are affected by several factors, as wind damage and defence potential of trees resulting from their physiological status. Pheromone traps represent valuable source of information about the bark beetle I. typographus population dynamics, although the collected data do not enable direct definition of its population level, especially in the protected areas with different and unstable (changed in 2017) approach to the protection of stands. As most of the information on beetles is captured in the first half of the growing season, the data collected till the end of July are sufficient for monitoring purposes; thus, the trapping should be reduced to the period May–July.

Opis:
Because of the very long regeneration period, final cuts in silver fir stands are always accompanied by the growing stock maintenance, which aims to maximize the revenue by increasing the share of harvest, trees with the highest timber value. We remove trees that have reached the maximum value and leave those whose value is still increasing. The remaining trees are the more valuable, the faster their value grows. The increase of a tree diameter is one of the factors that determines the value increment. The mature silver fir stand consists of trees that in youth grew in favourable light conditions and those that survived the long period of shade, achieving small dimensions. In such stands, the adjacent trees may vary greatly in diameter not related to their age. The aim of the study was to create a model describing the relationship between the increment of silver fir basal area (BAI) and the stand morphological features, age, and the dynamics of growth in early age. The research was carried out in the Brzesko Forest District and Forest Research Station in Krynica (S Poland). The sample size equalled 45 and 57 trees respectively. We used the composite form of linear mixed model. The significant positive effect on BAI (model 1) was found for the initial breast height diameter (dbh), the relative crown length as well as the age when trees reaches the 30 cm dbh. The negative impact was observed for Lorimer C18w index. The negative relationship with the relative BAI (model 2) was found for the initial dbh, slenderness, C18w index as well as the age when trees reaches the 30 cm dbh. Conditional and marginal determination coefficients reached 48 and 42% for model 1, and 62 and 38% for model 2 respectively. The results indicate the great possibility and purpose of growing stock maintenance in the pruned silver fir stands. Selecting the trees for the removal should be based on the target dbh. Had it been reached, the firs can still be characterized by a very good current BAI values. One should leave thinner firs with a relative crown length higher than average. Treatments releasing the crowns of the remaining firs, also at the cutting stage, are justified. Smaller growth at a young age (caused e.g. by shading), does not limit the possibility of obtaining trees with significant dimensions.

Opis:
The aim of the research was to assess the degree of damage to spruce trees and stands and to study their growth responses to the changing environmental conditions in the Sowie Mountains (Central Sudety Mts.). To assess the degree of damage to trees, three methods based on crown characteristics were used. The types of growth responses of trees to changing environmental conditions were additionally taken into account in one of the methods. Regardless of the assessment method, spruce stands in the Sowie Mountains demonstrated a high level of damage. The poorest growth conditions were found in the period 1966−1980 when a large number of trees showed negative growth responses, indicating a decrease in radial increment. The period 1996−2010 showed an improvement in the growth conditions of trees because the proportion of trees with negative growth responses decreased, while the proportion of trees with positive growth responses increased. It was also found that the growth conditions for spruce were more favourable in the lower montane forest zone (above 600 m a.s.l.), and less favourable at the foothills (below 600 m a.s.l.), which may be caused by the competition of beech replacing spruce in the lower locations in the mountains.

Opis:
Creating strip roads in second age class stands is an indispensible operation for carrying out thinning. It is especially important in places where there is an intention to do a first thinning using mechanised thinning operations. Felling trees to create strip roads results in altered conditions for the tree growth of neighbouring trees.In particular, this is due to an increase in exposure to sunlight. This can lead to changes in the growth of trees and consequently changes in the morphology of the trunk and the development of defects. The objective of this paper was to analyse the frequency of the presence of particular defects in the structure and shape of spruce ina five-year period after the creation of a strip road. The research was carried out in an artificially regenerated spruce stand within the spruce’s natural, northern habitat in Poland. A 34-year-old stand underwent a systematic thinning scheme which involved the removal of every eighth tree row. The analysis was carried out on trees growing both adjacent to the strip roads (which had a greater growing area around them and greater access to sunlight) as well as trees from further within the stand. Diameter growth was taken in three places: at breast height, in the middle of the trunk between breast height and the base of the crown, as well as at the base of the crown. The average incremental growth, pith eccentricity taper and ovality were calculated. No statistically significant difference in defects between the trees growing by the strip road and those growing further in the stand was observed. Greater taper on mid-tree logs in comparison to butt logs was observed. Insignificant changes in the morphology of the trunks, supports the validity of cutting strip roads in second age class stands.
Zakładanie szlaków operacyjnych staje się niezbędne przy stosowaniu współczesnych technologii w gospodarce leśnej. Ich obecność to również zwiększony dostęp do światła dla drzew rosnących na ich skraju, co z kolei może wpływać na różnice we wzroście tych drzew w porównaniu z drzewami wewnątrz drzewostanu. Celem pracy była analiza częstości występowania niektórych wad budowy i kształtu mogących wpływać na jakość surowca drzewnego w 5 lat po wykonaniu zabiegu. Drzewostan świerkowy w wieku 34 lat został poddany trzebieży schematycznej poprzez wycięcie co 8. rzędu drzew. Analizie poddano drzewa rosnące przy szlaku PS (z asymetrycznie większymi stoiskami i dostępem do światła) oraz drzewa wewnątrz drzewostanu ( WD 5–10 m od osi szlaku). Badano przyrosty na wysokości pierśnicy, w połowie długości między pierśnicą a podstawą korony i u podstawy korony oraz obliczono przeciętny przyrost, mimośrodowość rdzenia i zbieżystość. Nie zaobserwowano występowania statystycznie istotnych różnic pomiędzy analizowanymi cechami drzew PS i WD, jednakże u drzew rosnących PS zaobserwowano istotnie większą zbieżystość kłód środkowych w porównaniu z odziomkowymi. W krótkim okresie(5 lat) po założeniu szlaków w drzewostanie świerkowym II klasy wieku nie stwierdzono zatem statystycznie istotnych różnic w morfologii pni drzew rosnących przy szlaku i w drzewostanie. Niemniej jednak zaobserwowano: 1) tendencje do zwiększonych przyrostów u drzew PS (szczególnie w połowie pnia) w 5. roku po wykonaniu zabiegu oraz 2)wzrost zbieżystości kłód środkowych wyrobionych z drzew PS. Wyniki te sugerują przeprowadzenie podobnych badań w dłuższym odstępie czasowym (niż 5-letni)od założenia szlaków.

Opis:
The ‘Tisovik’reserve, located in the Belarusian part of the Białowieża Forest, holds an isolated relic stand of silver fir, situated 120 km to the north-east of the main forest. In order to preserve this relic fir stand, a ancestral conservative tillage consisting of the Jd 92 trial (plot I) and the Jd 94 trial (plots II and III) was established between 1992 and 1994 in the Polish part of the Białowieża Forest on the territory of the Hajnówka Forest District. The growth and development of the progeny of 20 firs were characterized by means of long-term observations made in these trials. In 2000 (at the age of 18), the firs in the Jd 92 trial (plot I) reached an average height of 394.86 cm with a mean diameter at breast height of 42.42 mm and the average rate of survival amounted to 75%. In the Jd 94 trial, the rate of fir survival on plot II was 70% (at the age of 15) with an average height of 277.08 cm and a diameter at breast height of 36.62 mm, while on plot III only 50 trees with an average height of 198.6 cm and a diameter at breast height of 24.49 mm survived. The results of this study show that the fir progeny in the ‘Tisovik’ reserve is of high breeding value. Therefore, the silver fir seed stock of the ‘Tisovik’ reserve is suitable for the establishment of new plantations in the Polish part of the Białowieża Forest and the Mazury-Podlasie Region.

The aim of the study was to develop a site index model for mountain spruce stands. The research material contained the height growth data obtained from stem analysis of 95 trees. The collected material was used to calculate the parameters of four dynamic growth equations, which allowed to determine site productivity and predict height growth based on age and height of stands. The equation that best describes the height growth of the examined spruces was selected from among different solutions using statistical criteria for assessing the accuracy of fitting empirical data and biological realism. The developed model can be used to predict the height growth and determine the site index for mountain spruce stands.

Opis:
The paper describes the accuracy of estimation of silver fir stem fresh mass on the basis of volume to weight conversion factor, derived from samples, collected from few different places along the stem. The research material contained 13 sample trees selected from homogenous 70−years old stand, situated in mountainous area of the Beskid Sądecki in Polish part of the Carpathians (S Poland). Volume over the bark of sample trees was calculated with section−wise method and the whole stem fresh biomass was directly weighted. For each sample tree three stem discs were collected at 1/6, 1/2 and 5/6 of tree height, their weight and volume were precisely determined and the biomass conversion factors (equivalent of stem density) were calculated. The assessment of the accuracy of whole fresh stem biomass was conducted according to five variants: for the biomass conversion factors derived from each individual stem disc (lower, middle or upper), from weighted mean density and on the basis of the constructed mixed model, where relative height and diameter were treated as fixed effects and influence of individual trees was included as a random term. The volume of sample fir stems ranged from 0.15 to 2.22 m3, while their fresh biomass varied between 138.1 and 1896.7 kg. Obtained results show that variation of the density was higher within stems than between them (coefficient of variation amounted to 8.4% i 3.3% respectively). The average density increased along stem, from 835.6 kg/m3 for lower part (1/6H) to 986.8 kg/m3 for the upper part (5/6H). Estimating the biomass on the basis of just lower stem disc resulted in the average relative error equal to –5.8%, while for middle stem disc the error was +1.2%, and for upper disc +11.3%. The use of conversion factors derived from weighted average density of all three stem discs resulted in average bias equal to –1,7% with standard error 1,0%. Despite the presence of mean bias of –2.3%, the constructed density model gave the most precise estimation of the stem biomass (standard error 0.7%), which indicates the reasons for its further improvements and usage.

The aim of this study was to: 1) describe the genetic structure of the population of old Picea abies trees in the Białowieża Primeval Forest and 2) design the genetic database for every examined tree in scope of 26 isoenzymatic loci containing: the genotype pattern, the number of stated alleles and the level of individual heterozygosity. We found that 101 out of 117 trees are characterized by a unique genotype pattern and 20 ones are completely homozygous individuals. The oldest Norway spruces in the Białowieża Primeval Forest are characterized by rather low level of genetic variation and their homozygous genotypes that are well adapted to their environment let them live to a ripe old age.

Opis:
Mitochondrial DNA marker was applied to 10 populations of silver fir from Poland and one from Belarusia. These populations were located within and beyond the natural range of silver fir. The marker exhibited two highly conserved alleles (first – 230 bp and second – 150 bp) based on an insertion−deletion of 80 bp in the fourth intron of the mitochondrial nad5 gene. The geographical distribution of the maternally inherited mitochondrial variation is known to support the existence of at least two refugia with two recolonizing maternal lineages remaining largely separated throughout the range. Our results provide that in all studied populations the first allele was discovered. Therefore we postulate that the silver fir migrate to Poland from the refugium in western Europe (probably from central Italy).

Pityogenes chalcographus L. (Col., Curculionidae, Scolytinae) is a pest of Norway spruce Picea abies (L.) Karst. characterized by large fluctuations in population size. Despite many publications devoted to P. chalcographus, no accurate method of estimating the population density of this species has been developed. The aim of this study was to develop a statistical method of estimating the total density of P. chalcographus colonising stems and branches of P. abies wind−fallen trees that enables calculation of estimation errors and does not require debarking of whole stems and branches. Linear functions were applied to calculate the total infestation density of stems and branches of P. abies windfalls. The mean relative errors of estimation for stems and branches were smaller than 35% and 45%, respectively.

Opis:
This paper is a review of fundamental information on bark beetles and their interactions with several predisposing factors (air pollution, drought/temperature interactions, windthrows, management activities) that are thought to contribute to the outbreaks in the High Tatra Mountains. The findings of many research projects indicate that the impact of air pollution on bark beetle populations is indirect and complex and that the disturbances in the physiology and natural resistance of trees may be of crucial importance to bark beetle population dynamics. An active forest protection approach is needed to be applied to the secondary Norway spruce forests affected in the past by human activity. Bark beetle populations in natural and near-natural forests (mainly in the upper montane zone) are regulated by natural mechanisms; bark beetles are therefore a natural factor contributing to forest development, including the transition of future generations of spruce.

Opis:
In this study, an Estonian tree-ring network of Norway spruce (Picea abies (L.) H.Karst.), originating from both living trees and dead wood of construction wood, was used for determining the growth variations over the past 350 years (AD 1657–2009). Regional curve standardization was used to remove the non-climatic growth variations from the individual tree-ring series prior to dendroclimatic analyses to focus on the low-frequency (long-term and -period) growth variations. Previously, the chronology has been shown to correlate markedly well with Estonian precipitation history. Here we further detail this dendroclimatic connection. Correlations between the Estonian precipitation and treerings improved systematically with both the number of meteorological stations included and with the documented technical advances in the network of instrumental weather observations. The observed June precipiation explains roughly 20 percent of the tree-ring variance over the period when the network of weather observations is densest (1946–2009). On decadal and longer scales, the June precipitation explains higher portion of tree-ring variance, roughly 50 percent, over the full instrumental era (1866–2009). Comparison with previously published and similarly standardized tree-ring chronology from south-eastern Finland, based on Scots pine tree-rings, showed that the two chronologies exhibit several coinciding periods of ameliorated and deteriorated growth.

The geographical distribution of mtDNA haplotypes in the Ukrainian Carpathians and their northern foothills indicates a very recent meeting of migration streams arriving from the Romanian Carpathians and Central Europe. In the western part of the Balkan Peninsula, two counterparallel migration streams are the most plausible explanation of the pattern observed. The haplotype typical for the Balkan Peninsula predominates along the Adrian coast, whereas the CentralEuropean haplotype is more represented in the inland.

Opis:
The study analysed short−term rhythm of radial increments of spruces from different elevations and their climate drivers. Two Norway spruce stands were chosen at the lower and upper montane forest belt in Roztoka Valley (DR) (1000−1050 m asl, 49°13 N, 20°04 E) and in Hala Gąsienicowa (HG) (1500−1550 m asl, 49°13 N, 20°04 E). 20 trees were sampled and one increment core was taken per tree. The sampled trees were dominant or co−dominant individuals without visible damage. To remove the age trend, the tree−ring widths values were standardized to annual sensitivity indices. Principal components analysis, bootstrapped correlation and pointer years analysis were used to classify sensitivity of investigated series and identify the climate factors, which determined annual variability of the radial increments. Pointer years were also determined by using interval trend method. The first principal component (PC1) accounts for 39% of the variance among all tree−ring series. The second component (PC2) accounts for 15% of the variance among the tree−ring series and divides the series into two groups. This grouping seems to express the lower and higher locations of the sites. The sensitivity series of spruces from both sites had different as well as similar features. These differences resulted from different tree's reaction to temperature in early spring and precipitation in spring and summer. The similarity of increment reactions of spruce from both sites was caused by their similar sensitivity to sunshine duration and precipitation in January, temperature in June and July, sunshine duration in June. Cluster analysis confirmed the impact of the climatic factors on differences of increment reactions of spruces. A number of the pointer years was higher at site located in the upper montane forest belt. Their chronology also consisted a stronger climatic signal. The climatic sensitivity which was specificity for a given climatic belt was recorded into individual tree series. For that reason, the tree−ring width series of trees are useful in the estimate of a climate−increment relationship. They can also be used to dividing dendroclimatic belts.

Opis:
Due to its hidden character, butt rot occurrence is not commonly included in the assessment of plus trees’ health status. Thus, the trees’ varied susceptibility to wood decay is not a target of breeding efforts. The aim of the study was to determine the extent of butt rot in fir and spruce plus trees from Carpathian seed stands. We employed the novel and non-invasive diagnostic method of sonic tomography to determine presence and severity of decay at the base of 110 plus trees of silver fir and 42 of Norway spruce. Butt rot in various stages of development occurred in 63% of investigated fir trees and in 45% of spruce trees. The proportion of damaged wood on the tomogram ranged from 0–38% in fir and 0–47% in spruce with similar average proportions of solid wood in all forest districts. The vast majority of trees was in the range of 80–90% solid wood. Plus trees of fir and spruce were affected by butt rot to a similar extent and the degree of damage increased with age in both species. However, a large variation in susceptibility to butt rot was found between individual trees leading to the conclusion that the identification of old trees, which wood is not decayed, may be the basis for further research on the resistance to butt rot.

Opis:
The present study examines the mechanism of natural and accelerated ageing processes in Norway spruce (Picea abies [L.] Karst.) seeds stored at low temperature for one (control) and eight years. The analyses of vitality, electrolyte leakage, protein composition and activity of the proton-pump ATPase (P-ATPase, EC.3.6.1.35) in plasma membrane of Norway spruce seeds have been investigated. Seeds collected in 1999 from northeastern Poland have been treated with accelerated ageing method and compared to the seeds of the same provenance, collected in 1992 (control). The vigor and the vitality of the Norway spruce seeds depend on the age of seeds. After 6 days of experiment both samples of seeds (artificially aged seeds and control) expressed the same percentage of germination and similar electrolyte leakage. Analysis of protein composition in the extracts showed an increased amount of some low molecular-weight proteins in artificially and naturally aged seeds compared to the control. Our results indicate similar level of P-ATPase activity in natural, artificially aged and control seeds. This suggests that natural ageing process can involve changes in plasma membrane protein composition but does not affect the P-ATPase activity.

Opis:
The main aim of the research was to study trees growth responses to the changing environmental conditions and to assess the degree of damage to trees taking into consideration their secondary crown. Based the material from plots established in 12 silver fir stands (tab.), chronologies were developed for trees in various age classes (fig. 1). 1950 saw a downward trend in the radial growth that continued till 1985, to be followed by an upturn lasting till 2000, when the radial growth stabilised. No significant changes in tree−growth were observed in the group of the youngest trees. Three types of growth response to environmental changes (positive, neutral and negative) were distinguished in the last three 15−year−long periods. In years 1970−1984 the largest proportion of firs indicated negative growth responses, while firs with positive response dominated in the period 2000−2014 (fig. 2). The period 1970−2014 saw a steady increase in the mean value of growth responses. The assessment of the top−crown growth (feature B) showed that more than 50% of the trees showed inhibited growth (fig. 3). The assessment of tree vitality (feature C) confirmed the dominance of trees with moderate crown vitality. The vitality of the secondary crowns (Zw) situated below the primary crowns (Zp) of firs was assessed on the basis of crown density and its length (formula [1]). Incorporating Zw in the assessment of tree damage (formula [2]) resulted in an increase in the vitality of the whole crown (Z) (fig. 4). Based on the defoliation, 73% of trees were found to be within damage class 2 (fig. 5). Another method of damage to trees determination was adopted (formula [3]) to assess the damage to fir stands and showed that the largest proportion of trees was with moderate damage (fig. 6). The damage index values obtained with this method were lower compared to the method that considers the defoliation exclusively. Even lower index values were obtained while using the method based on both damage index W and tree−growth response. Of the three discussed damage assessment methods, the most accurate is the method based on damage index Wz, taking into account the growth response of the entire crown (Z).

The objective of the research was to define the time span after which seedlings of silver fir (Abies alba Mill,) adapted to light conditions under the crowns of different tree species. The comparison of annual height increments of seedlings and the analysis of variance of light conditions permitted to preliminary assess the effect of individual species forming the canopy on the height response of regeneration.

Genetic markers in mitochondrial and chloroplast DNA were analysed to determine the native status and possibly trace the origin of the silver fir (Abies alba Mill.) growing outside this species natural range in Osusznica Forest District (northern Poland). The provenance of the extralimital populations were determined through comparison with reference samples from the native range of silver fir in Poland and Ukraine. Our results suggest that the Sudety Mts. are the most probable region of the origin of fir from Osusznica. It also seems that the plus seed stands in Osusznica can be treated as a valuable archive of the genetic resources of the fir from the Sudety and, if necessary, may support program of this species restitution.

Opis:
Mountain forests are strongly influenced by the extreme climate, short growing season and stress from environmental pollution and lower fertility of soils. The paper analyses the effect of the environment (climate and air pollutants) on the structure, production and dynamics of autochthonous spruce-beech forest stands in protected areas in the summit parts of the Orlické hory Mts., Czech Republic. The spatial pattern of tree layer was random in lower parts below the summit and aggregated under the hilltop phenomenon on an extreme edaphic site, such as aggregated horizontal structure of natural regeneration. In most cases, the relationship between the spatial pattern of tree layer and natural regeneration was significantly negative (α = 0.05) at a smaller distance (from stem to 0.6–6.1 m) except stands under the strong hilltop phenomenon (positive effect to 2.1 m). The stand density ranged from 440 to 760 trees ha–1 and the number of natural regeneration was 4 584–6 360 recruits ha–1. Dominant height decreased with increasing influence of hilltop phenomenon (P < 0.001). The volume of live trees was 239–536 m3 ha–1. The radial growth of dominant European beech (Fagus sylvatica L.) indicated a relatively balanced long-term trend of tree-ring width in 1900–2014, but diameter increment of admixed Norway spruce (Picea abies /L./ Karst.) after 1978 significantly decreased (P < 0.001) and since 1998 radial increment in spruce distinctly increased. Radial growth of spruce was significantly negatively correlated with mean SO2 and NOX concentrations, especially in April (P < 0.001), but there was no effect on radial growth of beech. Air pollution had a significantly higher negative effect on radial growth of spruce on the hilltop compared to the lower part of the hill. The correlation between radial increment and temperature was stronger than in precipitation for both species in mountain areas compared to lowlands. The hilltop phenomenon significantly influenced the structure of spruce-beech mountain forests. The lowest dynamics was observed in stands in middle slope parts compared to summit parts of the hill.

In our experiment the electrical parameters that affect early somatic embryos (ESEs) were investigated. High voltage was generated by a special high voltage generator. High voltages ranging from 5 to 20 kV and frequency of 1 Hz were applied longitudinal and transversal directly on the Petri dish with 2 days old ESEs of Picea abies for periods of 3 hours every day. One Petri dish was placed directly on top of the high voltage generator and on the other Petri dish were fixed two copper plates for transmission of high voltage. Petri dishes were exposed to high voltage for 14 days. After this time, the influence of high voltage was evaluated. To evaluate the experiment were used biological and chemical methods, which confirmed the changes in the growth of ESEs.
W naszym eksperymencie badane były parametry elektryczne, które wpływają na wczesne zarodki somatyczne (ESE). Wysokie napięcie wytworzono za pomocą specjalnego generatora. Wysokie napięcie, z przedziału od 5 do 20 kV i częstotliwości 1 Hz przykładano podłużnie i poprzecznie bezpośrednio do szalki Petriego z 2 dniowymi wczesnymi zarodkami somatycznymi Picea abies, codziennie na okres 3 godzin. Jedną szalkę umieszczano bezpośrednio na górnej części generatora wysokiego napięcia, a na drugiej szalce umieszczono dwie płytki miedziane do przenoszenia wysokiego napięcia. Szalki Petriego poddano działaniu wysokiego napięcia przez 14 dni. Po upływie tego czasu oceniano wpływ wysokiego napięcia. Do oceny zastosowano metody biologiczne i chemiczne. Potwierdziły one zmiany we wzroście wczesnych zarodków somatycznych (ESE).

Opis:
This paper presents results of dendrochronological analysis of spruce wood from the Wieliczka Salt Mine, one of the oldest mines in Poland. The wood came from the first level of the mine, from casings of drifts, chambers, mineshafts, short shafts, galleries and chapels. The oldest wood, representing spruce trees cut down in the 15th century, appears in the Wałczyn, August and Dusząca chambers, Bąkle chamber and Powroźnik gallery, as well as the cast between the Kaczorowski and Sroki chambers. Younger wood, from the 16th and 17th century, was recognized in the Krupiński, Dusząca, Reyna and Weszki chambers, the Leszno and Karol galleries, the Sułów short shaft, and the Lizak chapel. The 18th–19th century wood appears in the August, Wałczyn, Dusząca, Rex and Kloski chambers, the Klemens gallery, the Piżmowa chapel, and the Wałczyn short shaft. In two excavations of the August and Weszki chambers, fragments of 20 th century wood were recognized. Wood from old mines is a valuable source of information on history of the mining excavations or tools used in the mines. It also allows extending the scope of research of the mining archaeology.

Opis:
The investigation of zinc, cadmium, lead, copper and sulphur contents was carried out in the soil and in the needles of Picea abies L. Karst. in the Forest Promotional Complex "Lasy Beskidu Śląskiego". Samples of soil (from the level 0-10 cm) and annual, biennial and triennial needles of spruce were collected in autumn 2005 and 2006 from top parts of mountains: Rownica, Barania Góra and Czantoria. The highest heavy metals concentrations were determined in triennial needles of Picea abies collected from Czantoria and Barania Góra. The lowest content of sulphur and investigated metals was found in soil samples and heavy metals in plant material from the Rownica. Cadmium content (1.2 ug/g) was higher than normal level (0.2-0.8 ug/g) only triennial needles collected from Czantoria. The lead concentration (118-165 ug/g) in the soil of all investigated areas was exceed, lead level considered as allowable. Relatively low microelement concentrations in the soil and the needles of Picea abies L. Karst. indicated poor plant nutrition.
Prowadzono badania dotyczące zawartości metali ciężkich (Zn, Pb, Cu, Cd) w glebie i szpilkach Picea abies L. Karst. na terenie Leśnego Kompleksu Promocyjnego "Lasy Beskidu Śląskiego". Próbki gleby (z górnego poziomu) oraz szpilki jedno-, dwu- i trzyletnie świerka pobierano ze szczytowych partii gór: Równicy, Baraniej Góry i Czantorii jesienią 2005 i 2006 r. Stwierdzono najwyższe stężenia metali ciężkich w igłach trzyletnich zbieranych na Baraniej Górze i Czantorii. Najniższe koncentracje badanych metali i siarki zanotowano w próbkach gleby oraz w materiale roślinnym z Równicy. Zawartość Cd (1.2 ug/g) w trzyletnich igłach świerka pobieranych na Czantorii była wyższa od określanych jako stężenie nonnalne (0.2-0.8 ug/g). Stwierdzono przekroczenie dopuszczalnego poziomu dla Pb w glebie wszystkich badanych powierzchni (118-165 ug/g). Stosunkowo niskie stężenia mikroelementów zarówno w glebie, jak i igłach świerka wskazywać mogą na zły stan odżywienia roślin.

Opis:
The study on the structure of Norway spruce old−growth stands of original provenience in upper mountain zone was carried out in a nature reserve ‘Śnieżnik Kłodzki', located in the Lądek Zdrój Forest District (SW Poland). The fieldwork was conducted in three spruce stands located at the altitude of 1,215 and 1,235 m a.s.l. The breast height diameters (dbh) of living trees were characterized. The aim of this study is to characterize the structure of dbh of trees in spruce stands of subalpine forest. Implementation of the objective will be associated with the characteristics of empirical distributions dbh and an indication of theoretical distributions of continuous random variable best approximating the structure of dbh. The comparison of empirical dbh distributions with 36 theoretical distributions were carried out, but goodness−of−fit tests proven statistically significant compatibility with seventeen of them: beta (4−parameter), Cauchy, exponential power, folded normal, gamma (3−parameter), generalized logistic, Laplace, logistic, loglogistic, loglogistic (3−parameter), lognormal (3−parameter), noncentral chi−square, normal, smallest extreme value, triangular, Weibull and Weibull (3−parameter). The dbh distributions in upper mountain spruce stands are the best fitted with logistic distribution, and subsequently loglogistic (3−parameter), generalized logistic and Weibull (3−parameter) distributions. That four distributions can be used in individual tree growth models while generating structure dbh of trees in the stand. The knowledge of dbh structure in protected stands could be helpful in shaping spruce stand structure in planned silvicultural treatments, and shows the need for silvicultural treatments in upper mountain spruce stands.

Opis:
The aim of this study was to i) determine similarities and differences in the increment reaction of silver firs growing at different elevation, ii) identify climatic factors, which caused these response, and iii) determine dendroclimatic zones and identify a site, where a tree grew on the basis of tree−ring widths series. Studied stands were located in the Ustroń Forest District at the elevation of: 500−550 m a.s.l. (foothill zone, 18°59‵ E, 49°43‵ N) and 800−850 m a.s.l. (lower montane forest zone, 18°58‵ E, 49°43‵ N). In each stand 20 dominant firs were selected and one increment core per tree was taken. Tree−ring widths (fig. 1) were transformed into annual sensitivity index (fig. 2). Principal component analysis was used to reduce a number of original variables and classify the tree−ring series. Response function analysis was used to determine climate−radial increment relationships. The standardized series of firs on both sites were different in terms of the climate influence (fig. 3). The analysed trees responded differently to solar and thermal conditions in previous autumn and current summer as well as to pluvial conditions at the beginning of winter and in the second half of summer. The investigated firs had also common increment characteristics. The trees from both sites responded similarly to thermal, solar and pluvial conditions in February, solar and pluvial conditions in May and temperature in winter and summer (fig. 4). Climatic signal of each elevation zone was recorded by each tree and depended on the climatic conditions in given area. On the basis of standardized tree−ring series, dendroclimatic regionalization can be created and the stand, where a tree grew, can be identified.
