    Opis:
    The aim of this work was to compare the variability of Scots pine Pinus sylvestris L. seeds collected in three forest sites in the Radomsko Forest District. This comparison was mainly based on viability and weight of 1000 seeds, which was then used to calculate seed value for each sample. Furthermore, seed size was assessed by measuring their length, width and area, using the WinSeedle software. All evaluated samples belonged to viability class I. Seeds originating from the Bąkowa Góra forest range were characterized by the highest weight, best viability and the largest size. In the next stage of our research, we performed an analysis of variability parameters taking the colour of the seed coat into consideration. For this analysis, the seeds were divided into three colour groups (fawn, brown, black) and their vitality and weight were assessed separately. The share of fawn seeds was 9.4%, brown 39.6% and black 50.9%. The weight of 1000 seeds and seed size parameters of fawn seeds were slightly higher than those of the black and brown seeds. The fawn and black seeds belonged to vitality class I, while brown seeds belonged to vitality class II. Despite the observed variability, seeds belonging to different colour groups did not show statistically significant differences in other measured parameters. The factor with the greatest impact on the seed parameters was the site of origin, which differed in their forest site type. Larger and heavier seeds came from the broadleaved forest site compared to the coniferous forest sites.

    The aim of this work was to investigate the variability of different features in wych elm Ulmus glabra Huds. populations growing in the conservative plantation in the Kolonia Forest Subdistrict (Oleszyce Forest District). We examined the survival rate, height, and spring flushing of the elm trees as well as the occurrence of two leaf morphotypes after ten years since the establishment of the plantation. Statistically significant differences were found between the studied populations in terms of survival and height growth, while no difference was observed for spring flushing, which may be due to the close proximity in which the tested populations grow. The highest rate of survival was observed in the Bircza 33a population (87.3%), whereas the Lutowiska 40b population grew tallest (344.3 cm). Elms with leaves typical of the U. glabra ssp. montana (morphotype A – 84%) dominated the stand, while elms with leaves characteristic for the U. glabra ssp. glabra (morphotype B) were a minority with only 4%. However, within the Lutowiska 137g population, the share of morphotype B was as high as 25%

    The paper presents the assessment of the adaptive traits (survival rate and height growth) of 5−year−old silver fir one year after planting on conservation plots of the Carpathian Gene Bank (KGB) located in the territory of Wisła, Andrychów, Sucha, Nowy Targ, Krościenko, Nawojowa, Rymanów oraz Bircza forest districts. The conducted studies showed a high (over 90%) survival rate of the tested fir provenances. The growth of the West Carpathian (Beskid Śląski, Beskid Żywiecki, and Beskid Mały) fir provenances was high on the majority of the KGB conservation plots, while the height growth of fir stands from the central part of the Carpathian Mountains (Beskid Wyspowy, Beskid Sądecki, and Beskid Niski) was on an average level. The East Carpathian (Pogórze, Słonne and Bieszczady Mountains) provenances were significantly diversified in terms of the height and did not form a homogenous group.

    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:
    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.

    Critical transport velocity, thickness, width, length, angle of sliding friction and weight of small−leaved lime (Tilia cordata Mill.) seeds from five batches, harvested in four neighboring seed regions in Poland, were determined. The values of shape factor, cross−sectional area, volume and density were calculated for each seed. The results were compared using standard statistical methods (simple ANOVA, correlation, single−variable and multivariate regression analysis). The highest correlation was observed between weight of seeds and their thickness and width. Majority of regression equations developed in the study was characterized by a relatively high percentage of explained variation, taking into account the type of experimental material.

    Opis:
    The soil of former farmland greatly differs from forest soil, and significantly influences tree growth and development compared with other site factors. The effect may also be reflected indirectly in radial variability of wood. This study compared radial variation of wood density, compressive strength along the grain and static bending strength of wood of Scots pine trees growing on former farmland and forest soils. The analyses were conducted in eight mature pine stands. On the basis of the stand description, four stands were classified as growing on forest soil (L) and four as growing on former farmland soil (P). A total of 24 model trees were selected, twelve on each soil type. Analyses of wood properties were conducted along four axes from the cross sectional radius of the treesat breast height. Our analyses showed that radial variation in wood properties of Scots pine (from selected locations in Poland) growing on former farmland is similar to the variation among the control trees growing on forest soils. In both groups of trees, the lowest density and the lowest strength were in the pith (juvenile) zone. Wood with the highest density and greatest strength was located in the central part of the radius. Wood of Scots pine trees growing on former farmland soils in comparison to that of trees growing on forest soil was characterised by a statistically lower basic density, lower compressive strength along the grain and static bending strength.
