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.

Opis:
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:
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.
