Opis:
The studies were conducted in the years of 1997−2001. The effect of four methods of soil preparation (ploughing with double mouldboard plough LPZ−75, disc plough PTL−2, disc harrowing and ridge formation) on natural regeneration of pine under the canopy shelter was analysed. Significant differences in the density, height and vitality of seedlings in the variant II (ploughing with disc plough) and variant IV (ridge formation) were found in the second and third year of studies. In the following years the differences between the variants were insignificant due to the heavy damage of seedlings caused by the cockchafer larvae. Neither of the methods applied protected the seedlings against this damage.

Opis:
In most cases, mechanical site preparation (MSP) is a precondition if high−quality (natural or artificial) regeneration of forests is to be achieved. However, the measures involved here may differ in terms of the level of intervention of the soil environment, at both the surface and deeper down. The choice of MSP methods should be based on climatic conditions, site type and the species whose renewal is sought, while the effect should improve conditions for the emergence and growth of the young generation of trees, with the influence on the soil environment being limited as far as possible. The research sought to compare physical and chemical features of the soils of the microhabitats created in clear−cut areas as a result of MSP using either an LPz double mould−board forest plough (furrow and ridge), an active plough (furrow and ridge) and a forest mill (belt and beyond the belt) as compared with unscarified soil. Investigated physical features included grain size (content of sand, silt and clay), bulk density and actual moisture, while the chemical ones: pHH2O and pHKCl, exchangeable acidity, total content of N and C and the C/N ratio, P2O5 content and base cations Mg2+, Ca2+, K+ and Na+. The most invasive MSP method for the soil environment is the active plough, which leaves the ridge exposed to processes of the decomposition of organic matter (and the highest content of N, C, Mg2+, Ca2+ and K+). Equally, this method may pose the greatest threat of mineral components of the soil being leached, with impoverishment of the habitat ensuing. The forest mill in turn offers the least invasive MSP. Most of the physical and chemical features of soil (other than exchangeable acidity and pHH2O and pHKCl) both in the belt areas and beyond them differed little from the those characterising non−scarified soil. Also the analysed features determined for the furrows ploughed by the active or LPz ploughs or the belt prepared using the forest mill did not differ significantly.

The effect of the controlled mycorrhization with the fungus Hebeloma crustuliniforme, the application of fungicides (Bayleton 25 WP, Falcon 450 EC, Nimrod 250 EC and Siarkol Extra 80 WP) in the nursery and the use of two types of substrate (a mixture of sterilized Estonian peat with vermiculite and unsterilized Polish peat with perlite) on the growth, level of infestation by powdery mildew and form (single, multi−stem) of oak trees in the first four years after planting was analysed. The type of the substrate and controlled mycorrhization did not affect the growth of young trees. Oaks treated with Nimrod in the nursery were the tallest after outplanting, but grew slower compared to trees in other variants. The oaks protected with the triazole fungicides (Falcon and Bayleton) in the nursery showed higher level of infestation by powdery mildew in the plantation.

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:
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:
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.

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.
