Opis:
The paper analyses the variability of selected adaptive, growth and morphological parameters of 16 Scots pine provenances from Poland. Their silvicultural value and usefulness under the growth conditions in Central Poland were assessed. The empirical part was carried out on the experimental plot established in spring 1966 in Lipce Reymontowskie Forest Range, Rogów Forest Experimental Station. In subsequent surveys, the following characteristics were determined for each tree: diameter at the breast height, height, height of crown base and diameter of branches. All trees were also classified into 4 quality classes related to the stem straightness. The following analyses were performed: survival rate, course of height growth and diameter increment over age, variation of volume at single trees and whole stands level, diameter of branches, stem straightness, selected genetics and silvicultural properties. The assessment of silvicultural values pointed out that the best provenances include Dłużek, Karsko, Bolewice and Rychtal. Local provenances from Rogów and Spała are classified as the weak ones. Therefore in local Scots pine stands there is a need to improve quality, stability and yield. Obtained results deepen an existing knowledge on variability of Scots pine stands and demonstrate possibilities for verification of seed regionalization principles in Poland.

Opis:
The aim of this paper is to investigate and compare structural, mechanical and physical properties of wood of Norway spruce growing on experimental plot in Rogów (central Poland). The planting material consisted of seeds sourced from six selected provenances. Three of them originated from lowlands, while the others have mountain origins (tab. 1). The plot was established in 1975 and the wood was harvested in 2010. Wood samples were prepared and measured according to the Polish Standards describing those procedures. The following properties were subjected to the research and statistical analyses: average tree−ring width, share of latewood, wood density, compression strength parallel to grain, static bending, modulus of elasticity in static bending and the coeffi− cients of compression strength parallel to grain, static bending, and modulus of elasticity in static bending. Results of the investigation were correlated in the frame of each provenance. Wood density determines values of compression strength parallel to grain, static bending and modulus of elasticity in static bending. The higher wood density, the higher values of the mechanical properties. Ordering provenances by the wood density demonstrates the same results as ordering by values of compression strength parallel to grain. The high values of density and mechanical properties prove good technical quality of the analysed wood. The structural properties (the average tree−ring width and the share of latewood) are correlated to the wood density as well. They are additional features to describe wood quality, but are not as accurate as the mechanical properties. The quality of wood from all investigated provenances is high, what makes impossible to distinguish wood from selected provenances using applied features. Wood from Nowe Ramuki and Kartuzy (i.e. lowland) provenances has the best quality parameters, while one from Istebna Bukowiec and Stronie Śląskie (mountain) provenances demonstrated the worst properties (tab. 2). The results do not prove the opinion about the best quality of Norway spruce wood originating from the mountains.

Opis:
The programme of testing the progeny of permanent seed stands, parent trees, seed orchards and seedling seed orchards that has been run in Poland enables to determine the genetic value and silvicultural quality of the progeny of components of primary forest material. A better knowledge of population variability and adaptability to particular environmental conditions also allows for the updating and verification of principles regarding the use of the seed base in testing regions, as well as the determination of possibility for forest reproductive material to be transferred. The article presents the research on assessment of survival and growth among progeny from 26 permanent seed stands of silver fir that originates from Lublin, Radom and Łódź Regional Directorates of the State Forests, at four testing grounds located in the Kielce, Suchedniów, Tomaszów and Zwierzyniec forest districts. Each research plot was founded with 4 replicates, each with 3−year−old saplings. After 5 years of growth, mean rates of survival ranged from 70.4% at the Kielce site to92.7% in Tomaszów. The lowest survival rate (30.5%) was noted for local origin (Starachowice), while the highest (93.8%) characterised the local standard from Zwierzyniec. Mean height varied from 54.1 cm in the case of the Suchedniów to 80.0 cm in the case of Tomaszów, albeit with the shortest firs originating from the Starachowice local standard and the tallest from the Tomaszów local standard. Analysis of variance components revealed that the environmental conditions (described by study area) played major role in shaping the variability. This effect was responsible for around 75% of the variance in height and 60% of that relating to survival. In contrast, origin (genetic factor) was most likely responsible for 7% of the noted variance in height or 4% of that relating to survival.

Opis:
The paper presents investigation on influence of root shortening on growth of 2−years−old Norway spruce seedlings after their development in the nursery. Measurements of basic morphological features reveal that strong length reduction increases regeneration of spruce root system. Together with that, slight decrease in height and diameter increment of the main shoot can be observed. Shortening of spruce roots improves significantly the balance between above− and belowground parts of the seedlings as well.

Opis:
This paper describes the variability of Scots pine (Pinus sylvestris L.) provenances in the IUFRO experiment located in Rogów (central Poland). The silvicultural quality and growth of 17 European provenances at the age of 28 years were examined, including height, diameter at breast height, standing volume, straightness of stem and health status. Populations from Poland (Spała, Miło−młyn, Rychtal), Germany (Betzhorn, Lampertheim), France (Haguenau) and Hungary (Pornóapáti) characterized by the best growth parameters. In contrast, pines from Northern (Russia, Sweden) and Southern (Turkey, Montenegro and Bosnia and Herzegovina) Europe were smaller and thinner and, as a result, with lower standing volume. The smallest differences of pine populations were found in tree height. The highest mean tree height (11.68 m) was reported for Rychtal (Poland) provenance, while the lowest (6.77 m) for Çatacik (Turkey). The overall mean tree height in the whole experiment was 9.83 m. Diameter at breast height (dbh) varied more than the tree height. The highest mean dbh (129.91 mm) was reported for Haguenau (France) provenance, while the lowest (72.85 mm) again for Çatacik (Turkey). The overall mean dbh for all provenances equaled 107.12 mm. The highest differences of pine populations were found in the standing volume. The highest standing volume (19.05 m3/ha) was obtained for Pornóapáti (Hungary) provenance, while the lowest (163.72 m3/ha) again for Çatacik (Turkey). In terms of silvicultural quality, the northern provenances were classified as the best ones because of high proportion of trees with straight stems. The largest share of tress with straight stems occurred in the population of Serebryanskoe from Russia (60.8%), while the smallest of Haguenau from France (6.9%). The populations from Southern Europe (Maočnica, Prusačka Rijeka and Çatacik) show poor adaptation to environmental conditions of central Poland.

Opis:
European beech is one of the most important broadleaved tree species in Poland and will play probably even more significant role in the future due to the predicted climate change. The main objectives of this study was to analyse and compare the growth parameters and morphological traits between 23 European beech provenances from south−eastern Poland (fig. 1). The research was conducted on the experimental plot established in Łosie Forest District in 2006. The experiment employed a randomized complete block design consisting of 92 plots (23 provenances×4 blocks). On each plot 100 trees representing given provenance were planted in 1.5×1.5 m spacing. In the spring and autumn 2015 we measured and determined the following parameters for the subsample of 36 trees on each plot: survival rate, tree height, diameter at breast height, diameter of the branch at the middle height of the crown length, stem straightness, crown shape, tendency to create forks, mean angle between stem and branches and spring phenology. We also included different eco−physiographical characteristics for each provenances (tab. 1). We performed basic statistics to describe mean values and standard errors (fig. 2, tab. 2) and finally we quantified the interaction between traits and eco−physiographical characteristics by Principal Component Analysis (PCA) (fig 3, tab. 3). The obtained results indicates that under growth conditions on experimental trial in Łosie Forest District, the provenances from lower elevated regions with lower precipitation and higher mean temperature (i.e. more arid conditions; Kielce and Narol provenances) were characterized by thicker dbh and branch dimeters in contrast to regions from southern Poland (Łosie, Bricza 1, Stary Sącz and Nawojowa). European beech provenances from regions with more humid conditions and lower mean annual temperature, as well as shorter vegetation season are characterized by higher survival rate. They are also higher than other provenances, but reveal the lower ratio dbh to branch diameter.

The paper presents the study on the height of 10−12−year−old pedunculate oak regeneration in clear−cut gaps in three fertility variants: mezotrophic of poorer productivity (fresh mixed coniferous forest – BMśw), mezotrophic of higher productivity (fresh mixed deciduous forest – LMśw) and eutrophic (fresh deciduous forest – Lśw). BMśw and LMśw were represented by two locations: Gostynin (G) and Parczew (P), while Lśw – by one: Czarna Białostocka (CzB). We analysed the variation of oak height in the patches along the north−south (N−S) and east−west (E−W) gap axes. In each location 3−5 gaps were selected and measurements taken on three transects along the N−S axis located in the western (W), central (C) and eastern (E) part. Significant differences in oak height were found along the N−S axis. Oaks in the BMśw and LMśw habitats in the south−central part, and those in the Lśw habitat in the centre−northern part of the patch were the highest. The height growth of oaks on sandy soils (BMśw, LMśw) was found to be limited by moisture deficit, while on loamy soils (Lśw) – by light deficiency. The differences in oak height along the E−W axis were smaller and less apparent, indicating a tendency towards the reduction of their height growth in the central part of the gap.

pedunculate oak
Opis:
Pedunculate oak is a species of major economic importance in Polish forests. This species seedlings constitute 18.9% of the nursery production in the country. One of the most widespread fungal disease these oaks face is the oak powdery mildew induced by Erysiphe alphitoides. Nursery production is on the lookout for environment−friendly means of plant protection as well as growth simulators capable of raising levels of productivity. Our objectives was to assess two preparation treatments regarded as biostimulators (registered as fertilisers under the names Apol−Humus and Apol−Hum Chelat) in the raising of seedlings of pedunculate oak in bare−root nursery conditions. The experiment included 6 variants with seedlings treated with the above agents, protected against mildew in the traditional way using Falcon 460 EC, treated with fertiliser and fungicide at the same time, or left as control specimens with no measures taken. All preparations were applied by means of foliar spraying 5 times in the course of the season. Survival of seedlings was then assessed at the season end, along with biometric features like root−collar diameter, length of main root and stem, dry mass of leaves and stem, and degree of oak powdery mildew attack. Results indicated curtailment of mildew infection of oak seedlings thanks to both of the biostimulators, albeit to a more limited extent than when fungicide was applied. No stimulation of seedling growth was achieved, however, though the most favourable biometric parameters characterised the oaks supplied with both biostimulator and fungicide. Significantly higher survival rate was noted for oaks offered effective protection against mildew, in the variants with the fungicide or with simultaneous application of Apol−Humus or Apol−Hum Chelat with Falcon. The research points to the two biostimulators under study (based on natural components) being suitable for use in the nursery production of pedunculate oak seedlings, with it being presumed that either or both can allow for reduction in amount of fungicide necessary to be used to safeguard seedlings against mildew.

Opis:
This paper presents the genetic variability in the growth parameters and morphological traits, as well as the silvicultural quality of progeny of 23 European beech (Fagus sylvatica L.) provenances from south−eastern Poland. The research was conducted on the experimental plot established in the Łosie Forest District in spring 2006. After 10 years, during the spring and autumn, we determined and measured the spring phenology and survival rate, the diameter at breast height (dbh), the tree height, and the straightness of trunk. The results obtained point out the considerable variability of analysed features, both within and between different beech populations (tab.). Highest and lowest survival rates are noted for the beeches from Lutowiska and Leżajsk (populations 451 and 461), respectively (fig. 2). Lowest mean height and dbh were achieved by beeches from Bircza (453), while the tallest and broadest trees were from the Kielce population (390) (fig. 3−4). The overall silvicultural assessment based on survival, height, dbh, spring phenological phases and straightness of the trunk revealed that the most valuable populations of beech are those originating from Kielce (390), Bircza (454), Strzyżów (459), Lesko (452), Rymanów (457) and Lutowiska (451). In turn, the analysis resulted in least favourable assessments for beeches from Bircza (453) and Gromnik (362). Thus, we confirmed also that trees of local origin are not always best−adapted to (and do not always grow best in) the place they originate from. The obtained results are highly relevant from the principles of creating the seed source regions for beech in Poland, as the proper selection of a population for the given place of growth may yield benefits for forest ecology and management.

Opis:
Paper presents an analysis of phenotypical variation and an evaluation of silvicultural quality of progeny from 27 beech stands around Poland that grow on the provenance plot in the Brzeziny Forest District (51.791997°N, 19.813841°E). The trial commenced in spring 1996, on the basis of 2−year−old saplings with covered root systems. A randomised block method with 3 replications was applied, with subsequent measurements and analyses carried out in 2015, following 20 years of growth. The considered features included height, breast−height diameter, crown habit, trunk curvature and height of branching. Single−factor analysis of variance and Tukey’s HSD test were applied to determine the significance of differences among provenances. The largest mean height was attained by beeches originating from Gdańsk, Szczecinek and Bierzwnik. The least−tall beeches were in turn those whose origins were in Tomaszów, Łagów and Grodzisk. The greatest intra−population variation in height characterised the beeches from Gryfino and Krucz, while the most limited variation was noted for Gdańsk population. The beeches of greatest girth were again those deriving from Gdańsk, Bierzwnik and Szczecinek populations, as well as the one from Kwidzyn 15. The lowest values for diameter at breast height were again noted for the Grodzisk, Tomaszów and Łagów provenances. Marked intra−population variation in this feature characterised trees from the Gryfino, Bieszczady National Park (42), Zdrojów and Krucz provenances. The populations also differered in relation to analysed more−qualitative features. The group of populations prized most in terms of their overall silvicultural quality included Gryfino, Grodzisk, Zdrojów, Bieszczady National Park, Bierzwnik and Szczecinek provenances. In contrast, only low quality was manifested by beeches from Tomaszów, Rymanów, Wejherowo, Młynary, Golub− −Dobrzyń and Kwidzyn provenances. In general, populations originating from the north (especially Pomerania) achieved better growth and a more favourable quality evaluation than those from the south, and sites located near the range limits of the species (fig. 7). The obtained results show that northern Poland boasts the most plastic populations of beech. Equally, it was not possible to establish that populations of local origin were superior in terms of growth to those originating in more far−flung parts of Poland. Furthermore, assessments of different populations in terms of their growth and quality features often proved highly disparate.
