    Opis:
    The aim of the study was to estimate the ecotype diversity of Fagus sylvatica L. in the context of the genetic variation within the natural range of its distribution in Poland. The study covered 13 beech provenances from the selected seed stand. Additionally, 13 natural beech populations were subjected to analysis with special consideration taken of the diversity of this species in the forest complexes of the Bieszczady region. The high inter−population variation was proved by way of natural selection processes depending on site−climate conditions. The results point out to the need of selection of provenances to match the individual environmental conditions.

    Opis:
    The study evaluated the sensitivity of European larch (Larix decidua) of two provenances to thermo−pluvial conditions on the provenance plot located in Sękocin Stary (52°05‵ N, 20°51‵ E, 125 m a.s.l.). The studied larches originated from Pelplin (lowland, northern Poland, 50 m a.s.l.) and Szczytna (upland, southern Poland, 525 m a.s.l.). The trees of both provenances differed in terms of their quantitative and qualitative breeding characteristics. The trees originated from different climatic regions whose climate was also different from the climate of the provenance plot. Values of the size of the radial increments measured at cores extracted from the trees were the measure of their sensitivity to the climatic factor. The cluster and principal component analyses were used to classify the trees according to their features of the short−term rhythm of the radial increments. The response function and pointer years analyses were used to evaluate climate−growth relationships. The results of the study show the trees of both provenances have similar sensitivity to the thermo−pluvial conditions in the previous September, the temperature in March and the precipitation in May of the year of tree−ring formation. The larches of Pelplin provenance, in contrast to the trees of Szczytna provenance, were sensitive to the low temperature in February and the low precipitation in the growing season. These features could be one of the causes of the lower incremental abilities of the trees of Pelplin provenance. The larches of Szczytna provenance had higher frost tolerance in February and drought tolerance in summer.

    The paper contains results of the provenance−family experiment with three provenances and 24 families. The studies focused on the height of trees at the age of 3 to 11 years. The genetic variance of 3−year−old seedlings participated in up to 44% to the total variance. In subsequent years, this participation was close to zero due to the decline in participation of environmental variance after outplanting. At the age of 9 years, the genetic component of the variance was noted again. Depending on the provenance the heritability for the height trait at the age of 9 to 11 oscillated from near zero (provenance from Zalesie) to 0.61 (provenance from Tronçais).

    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.

    The paper reports on the results of the provenance experiment with Pinus sylvestris L. of the SP IUFRO 1982 series. The analysis comprised taxation parameters, specifically productivity. Polish populations appeared to be superior ones. Northern and southern provenances were found to represent an inferior quality of the analysed parameters. The dependence of traits on latitude of origin can be described by parabolic equations. Southern populations show poorer adaptation to the Supraśl environmental conditions than the northern ones.

    Opis:
    The study objective was to verify the hypothesis on ecotypic variation in beech and ineffectiveness of transferring its reproductive material over larger distances. Beech nuts were collected in the autumn of 1990. Experimental sites were established in the Baligród and Oleszyce forest districts (SE Poland). On single plots of 18.00×13.75 m (247.5 m2), a total of 110 three−years−old seedlings were planted in a 1.50×1.25 m spacing in autumn 1993. Single row of mountain ash was left between the plots. In the period of 1994−2016 a series of analyses was conducted concerning adaptation, growth, phenological and qualitative traits. Height was measured on all trees using a measuring stick, except for the year 2016, when hypsometer was used to measure approximately 20 heights and remaining ones were determined based on the height curve. Results were analysed using univariate analysis of variance based on the random model, followed by Duncan’s multiple range test for each experimental site and year of the study. For 2016 ordering of populations in each of the experimental sites was compared using Spearman’s rank correlation test. In terms of survival rates in Oleszyce site the local provenance from Oleszyce proved to be superior. In all the years of the measurements it was characterised by the highest survival rate. In this respect the Komańcza and Lutowiska provenances from the Bieszczady Mountains turned out to be the worst ones. In the experimental site in Baligród, the Barlinek and Połczyn provenances outranked the others in terms of their survival rates, while in 2016 it was the population from Komańcza. Tree height effects in Oleszyce site showed that the local population from Oleszyce grows best, while the Pomeranian population from Jamy was also exceptional. The Bieszczady populations (Komańcza and Lutowiska) are characterised by the worst growth traits. In the experimental site in Baligród, the local Baligród population is characterised by poorest growth, similarly to the other ones from the Bieszczady. In terms of growth, the Western Pomeranian population from Gryfino is exceptional. As far as all the evaluated traits are concerned the investigated populations exhibit considerable variability, as no geographic ordination could be found. It was confirmed that imported populations, even from long distances, may exceed local populations in terms of their adaptation traits and growth rates.

    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.

    The studies were based on the material collected in the provenance experiment established in the territory of the Milicz Forest District where 78 pedunculate (Quercus robur L.) and sessile oak (Quercus petraea [Matt.] Liebl.) provenances from all over the country were planted in 5 replications. The izoenzyme analyses took in dormant buds from 300 trees of randomly selected 5 pedunculate oak and 5 sessile oak provenances. Variation of 6 enzymatic systems was the subject of the analysis. The studied oak populations exhibited a relatively high level of genetic variation, however, it was lower in comparison with the populations from other regions of Europe. Generally, the variation of the sessile oak was grater than of the pedunculate oak. The calculated genetic distance between the two oak species was 0.0284 and it exceeded genetic distances among the populations within the species.

    The study focuses on the variation of the adaptation features of forty partial populations of beech from the area managed by the Katowice Regional Forest Directorate. The growth and development of the provenances were assessed in the years 1998−2003 by measuring the height and survival of seedlings in the juvenile phase, i.e. up to the fourth year of planting on comparative plantations of the Regional Gene Bank that were established at two different forest sites of the area. The selection indices of the provenances were calculated from the variation components.

    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 experimental area is located in the Wêgorzyno Forest Sub-District, £obez Forest District. 29 Polish provenances of beech from their natural range were growth in a completely randomized block design with four replications. In 2010, after the end of the growing season, measurements were carried out on the experimental plot, including: determination of the survival rate and the diameter at breast height, and height of trees. Moreover, the total basal area and the total volume were calculated. Using ANOVA, statistically significant differences between provenances were apparent for four of the five traits measured; all except diameter at breast height. Provenances characterized by high values for the analyzed traits were considered the best adapted to the habitat conditions in the experimental plot, while provenances reaching low values were considered unsuitable for use under the conditions similar to those at the trial site location.

    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.
