    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:
    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:
    Mechanical site preparation is recommended to create optimum conditions for seed germination and seedling growth in a clear−cut area. Lack of soil scarification or less−intense methods may be more suitable from an environmental point of view, but can result in a failure to obtain natural regeneration. This study compared the effects of three mechanical site preparation methods (SPM) characterized by different levels of soil scarification (i.e. double mould−board forest plough (LPz), active plough (PA) or forest mill (FL)), as well as a control variant without mechanical site preparation, on height, density, spatial distribution and survival among naturally regenerating Scots pines (Pinus sylvestris L.) in the first 2 years of growth in a clear−cut area of NE Poland. The experiment was based around a four−block randomized block design involving the four variants. Seedling height was measured at the end of the first and second growing seasons, with measurements performed on 8 meter−wide transects extending across the entire width of the cleat−cut. We found no effect of SPM on seedling height, though the density of seedlings regenerating naturally was found to be dependent. After two years, the highest density was achieved in the PA variant (8.1 seedlings/m2) and the FL variant (7.0 seedlings/m2). A significantly lower density characterized the LPz variant (5.1 seedlings/m2) and the lowest of all the variant without soil scarification (3.2 seedlings/m2). The most homogeneous natural regeneration was achieved following the use of PA (2.6% of 1 m2 plots without seedlings after two growing seasons), while the least homogeneous was the variant without soil scarification (22.4% of 1 m2 plots). Survival of pines after the second growing seasons was quite high (over 80%), and did not differ significantly depending on the SPM. Our research therefore confirmed that, in the absence of mechanical site preparation, natural regeneration of sufficient density and homogeneity cannot be obtained. The best natural regeneration was obtained on sites prepared with PA, and FL scarification being only slightly less favorable. The low density and uneven distribution of seedlings on the soil prepared with LPz was a surprising result. The probable reason for this lay in the high precipitation in the first growing season. On one hand, this provided very good moisture conditions for seed germination and seedling growth on a substrate with high porosity in the PA and FL variants, but on the other the high bulk density of mineral soil in the LPz variant led to oxygen deficit.

    Opis:
    The objective of the study was to analyse the density, survival, height and quality of Scots pine (Pinus sylvestris L.) seedlings growing in the furrows and on the ridges. On poor sandy soils (fresh coniferous forest habitat) the performance of seedlings growing on ridges was superior while in a moderately fertile type of mixed coniferous forest habitat where the competition of forest floor vegetation was high, natural regeneration occurred almost entirely in the furrows.

    Opis:
    The paper was aimed at determination of the effect of different tree density in the naturally regenerated monotypic and even aged young Scots pine stands growing in the fresh coniferous or mixed fresh coniferous forest sites on their further development. Research was carried out in Nowa Dęba Forest District (south−eastern Poland). A total of 12 research plots (160×40 m) were established in the selected stands. Plots were divided into 4 equal square pieces (40×40 m), where different methods of tending were applied (variant A – control, variant B – thinned, leaving 16 thousand trees/ha, variant C – thinned, leaving 10 thousand trees/ha, variant D – thinned, leaving 6 thousand trees/ha). The thinning was carried out in April 2007. In subsequent years (2007−2010), selected elements of stand structure like: height, height increment, density and damage resulting from abiotic and biotic factors were determined. Tree density significantly influenced both height increment and qualitative (tree shape) characteristics of naturally regenerated young pine trees. In the course of early thinnings, the number of trees needs to be reduced approximately down to the 10−16 th. stems/ha in the first stage of growth (seedlings), and further down to about 6 th./ha in the coppice stage. Such density enhances the chance of good growth and silvicultural quality of the stand. Noteworthy, even the heavy thinning does not significantly impact the actual proportion of both biotic (e.g. ungulate browsing) and abiotic (e.g. heavy snow) damage in the young naturally regenerated Scots pine forest stands.

    Opis:
    Different methods of logging slash management (LSM) and methods of soil preparation (MSP) can create different conditions for the growth of forest trees. This occurs through variation in soil aeration, tree nutrition or microbial conditions. These factors are modified by climate, soil fertility, treats from insects or fungal pathogens and renewed species. The aim of this study was to compare effects of three LSM methods: 1) crushing and mixing with the soil by Mery Crusher, 2) chopping and leaving on the soil surface, and 3) removal from the clear−cut, and three MSP: 1) double−mouldboard forest plough LPz−75, 2) active plough U−162, and 3) forest mill FAO−FAR FV 4088 on biometric parameters, density and survival of six−years old Scots pine seedlings. Field research was conducted in Narol Forest District (south−eastern Poland). The soil in the study area was classified as brown podzolic, formed on loose sands with typical mor humus.The experiment was established by planting 10 000 one−year−old pine seedlings per hectare, after clear cut and followed by a two−factor block design consisting of nine variants distinguished on the basis of LSM and MSP randomly assigned to each of the three blocks. Tree height and root collar diameter were measured three times, at the end of 1st, 3rd and 6th growing season. The results showed no statistically significant differences in the size of the analyzed parameters of planted seedlings. Seedlings in the variant with site preparation by crusher and forest mill were slightly higher and thicker. This indicates the better trophic conditions in that variant. LSM did not affect either seedlings density or their survival. A slightly higher survival rate and tree density occurred in variants with crusher regardless of soil preparation method. It follows that, all presented experimental variants give similar results. Therefore, selection of the most appropriate methods of site and soil preparation should primarily respect ecological and economic indicators, and such local factors as microclimate, mainly precipitation, site fertility and threats from pests and fungal diseases.

Both treatments stimulated the growth of seedlings. The effect of Biochikol was found only in the nursery irrespective of the used doses of the preparation. The effect of mycorrhization on pine growth was stronger compared to the application of Biochikol both in the nursery and plantation.

    The aim of the study was to assess the effect of the application of Sincocin AL and inoculation with the fungi Hebeloma crustuliniforme or Laccaria bicolor on the growth and level of mycorrhizal colonization of Scots pine seedlings. Sincocin had no effect on the development of biometric parameters of pine seedlings inoculated with L. bicolor, it limited the growth of non−inoculated seedlings and stimulated the growth of the seedlings from the variant with H. crustuliniforme. Sincocin did not cause changes in the proportion of the mycorrhizae formed by H. crustuliniforme or L. bicolor, and affected in different ways (stimulation, inhibition, no effect) the spontaneous formation of mycorrhizae.

    Opis:
    In the paper, an assessment of tree population dynamics in the old−growth stands of the managed part of the Białowieża Forest is presented. Data from five permanent sample plots with a total size of 9.3 ha and six inventories that cover the period 1949−2006, were used. Depending on the dynamic status, determined on the basis of changes in a number of individuals per hectare, basal area and quadratic mean diameter, three major groups of tree species were distinguished: 1) an increasing group, containing only hornbeam and lime; 2) a stable group, involving alder and spruce and 3) a declining group consisting of oak, ash, maple, pine, birch, elm and aspen.

    Opis:
    An assessment of the current dynamic status of tree species occurring in the Strict Reserve of the Białowieża National Park is presented. On the basis of long−term trends and analysis of large−scale inventory data, the three major groups of trees are distinguished: 1) ‘safe’ group, containing hornbeam and lime, 2) ‘presently safe, but declining in a long−term run’ group, involving spruce, birch and alder, and 3) ‘threatened and highly threatened’ group, consisting of oak, pine, ash, maple, elm and aspen.
