    Opis:
    The paper discusses conditions and problems concerning natural regeneration of pine in the „Puszcza Białowieska” Promotional Forest Complex. The studies on pine regeneration established from self−seeding were carried out on permanent experimental plots occupied by fresh and fresh mixed coniferous forests site types. A space filling index used in the experiment was to define space occupied by pine regeneration the so−called „height sum”. A significance test of differences in mean values between the abundance and height sum (t−Student's test) was used for each experimental variant within the forests site types. Natural regeneration in the Białowieża Forest occurs infrequently. It can be found mainly in loose pine stands growing in fresh coniferous forest site types. Pine naturally regenerates most successfully in fresh and fresh mixed coniferous forest site types, on fenced clear−cuts with a few reserved trees, with soil prepared in furrows and well−performed tending treatments, as well as in pine stands with stocking 0.4 providing that the same conditions are maintained. The primary condition for successful natural regeneration of pine in the Białowieża Forest is its protection against animals in the form of fencing.

    Opis:
    Permanently balanced forest economy demands today a resignation from a constant model of the forest stand, which preferred the productive function of the forest, mostly without any consideration to its natural values formed by Mother Nature. Implanting on Polish grounds principles of multifunctional forest districts acknowledged as a breeding object of the whole forest ecosystem, giving in that way the forest economy a proecological dimension. Its a result from a general progress of civilization and achievements in forest science; reaching towards the needs and expectations from the society gaining a general acceptation from different environments. One of the fundamental elements implementing the ecosystem is to rebuild deformed and artificially barred forest phytocenosis. This refers especially to pure pine stands on habitats, in which trophoism potential explains breeding habitats species variety. A good help for the forester in this area can be a natural succesion of good, noble broad−leaved species like for example the oak. Succesion of this species takes on a special meaning in poor habitats, in which it without any special imposes enriches the biocenose with the whole positive outcome accompanying this process; it can also be a valuable clue to the potential fertility in the habitat and the complexity in the forest vegetation community. An important task is to lead the way for the oaks development from succesion to its fullest use as a natural presence in creating the future forest generation. The article below is devoted to this question describing the natural up growth of the oak in pine stands on the coniferous forest habitats in Forest District Różanna and the methods and results in which they are used for breeding.

    Pine stands growing in the littoral zone of Bełdany Lake were established by natural regeneration. On the sites under study pine forms multi−generation stands and regenerates continuously showing two culmination periods in the years 1770−1800 and 1930−1980. Pine population at the age of 200−230 years retains good quality and high vitality. Similarly, younger generation pines that grow under the shelter of the canopy even for 100 years retain the attributes of normal growth after being exposed.

    Opis:
    The aim of this study was to evaluate the practical feasibility of two forest regeneration methods using Scots pine Pinus sylvestris L. To this end, comparative experiments were established in the Złotoryja and Legnica Forest Districts. The site in Złotoryja had been clear cut, while the experimental plot in Legnica was established at a location damaged by wind in 2009 and cleared from wind throws and wind-broken trees before the experiment. Four different dates for sowing and two for planting were chosen in order to investigate the potential forest regeneration with respect to time. Both experiments were established according to the same design: a complete random block design with five replication blocks. To each plot we applied approximately 53 g (1.2 kg/ha) of seeds and planted 230 seedlings (10 200 seedlings/ha). In 2017, the height of the pine trees was recorded and their increment in height was measured in 2016 as well as 2017. A preliminary analysis of results was conducted using ANOVA for multiple experiments in order to identify significant differences and to then combine variables to form homogeneous groups to which the Duncan multiple range test could be applied. For growth traits, the ANOVA showed significant differences between experimental sights as well as a significant interaction of factors with the experimental site. In terms of planting, April was the most advantageous resulting in the greatest tree height in both forest districts, while in the Legnica Forest District the saplings planted in April also showed the greatest annual increments. Among the sowing dates, the most advantageous was the winter sowing, while the April sowing date produced the least desirable results. In conclusion, both sowing and planting are effective methods to establish pine cultures in coniferous forest. Furthermore, both methods may be performed at the currently recommended spring date, but they may also be postponed to summer and winter dates provided favorable weather conditions prevail.

    Opis:
    The effects of pine and oak forest litter on mycorrhizal status of 2−year−old Pinus sylvestris L. seedlings grown in a bare−root nursery was investigated. The research was carried out in the nursery of Vilnius University Botanical Garden in Lithuania. Ectomycorrhizal communities were assessed by a combination of morphological and molecular techniques. Statistical analysis revealed significant effect of litter treatment on some growth parameters of seedlings: seedling height, needle dry weight and total seedling weight. The survival rate of seedlings was significantly highest for oak litter, intermediate for pine litter, and lowest for control soil. Pine seedlings were colonized by indigenous ecto− and ectendomycorrhizal symbionts. Seven mycorrhizal species (Suillus luteus, S. variegatus, Wilcoxina mikolae, Tuber sp., Tomentella sp., Cenococcum geophilum, Amphinema byssoides) were distinguished on the roots of pine seedlings as well as one ectomycorrhizal symbiont not identified to species level. In total, 6 mycorrhizal types were found in control soil, 5 in pine litter, and 8 in oak litter. Suilloid (S. luteus and S. variegatus) and Wilcoxina mycorrhizae were dominant on tested seedlings, irrespective of litter addition. Seedlings grown in untreated nursery soil were 34% colonized by W. mikolae, while suilloid mycorrhizae were dominant after litter treatment (81% in pine litter and 63% in oak litter). We may conclude that suilloid mycorrhizae are better adapted to the conditions related to litter addition than W. mikolae.

    Opis:
    The aim of the study was to determine the rate of mineralization of needles in a pine stand in relation to site and to microbiological conditions occurring on dune slopes of contrasting aspects. The research was conducted in the old−growth pine forest overgrowing a latitudinally located dune in the Bydgoska Forest (N Poland). On contrasting dune slopes (northern and southern) rate of mineralization of pine needles was investigated in the 2−years experiment (2012−2014) with the litterbag method. Besides, following investigations were conducted in the middle part of both slopes: 1. dynamics of soil moisture and soil temperature were measured at a depth of 3 cm for 18 days during the 2013 growing season (interval of 2 weeks was applied) and 2. populations of bacteria and fungi were determined for all subhorizons of organic soil horizon (Ol, Of, Oh) as well as for a mineral horizon (AEs) of both soils. Weight loss of needles was found to be higher on northern than on a southern slope what was consequently stated for all 4 terms of taking measurements (6, 12, 18 and 24 months after placement of litterbags). The discrepancy has increased with time and after 2 years it equaled 14.7% when the loss was 61.1% for northern and 46.4% for a southern slope. It could be surprising that such differences were found in spite a sunny slope was characterized by stated in a study higher soil temperature. It should have a stimulating effect on mineralization of organic material; however a soil located on a southern slope was also found as much drier. Thus, the periodic deficiency of soil moisture was indicated as a limiting factor for occurrence of both bacteria and fungi on a southern slope due to the numbers of both groups of microorganisms were much lower on the slope than on a northern aspect. Conditioned by more favourable site parameters, higher number of microbial population occurring on a shadow slope could explain higher rate of mineralization of needles stated for the slope aspect. The moisture factor can be of especially high significance for microbial occurrence and activity and thus for litter decomposition just in dry inland dune ecosystems. It was concluded that in relatively monotonous pine forests overgrowing dry and poor in nutrients soils of inland dunes the slope aspect is an agent significantly differentiating both site and soil microbial conditions.

    Opis:
    Paper presents analysis of differences in conventional wood density of Scots pine measured at breast height regarding the geographical location of stands, forest habitat type, stand age and associated parameters such as density in the mid−length of the stem, density in the upper end of the stem and diameter at breast height. To investigate the impact of these factors, an analysis of covariance was used in accordance with two models specifically developed for this purpose. We found dependence of conventional wood density on the type of forest habitat and geographical location of the stand. The highest density was detected in dry coniferous forests, while the smallest in fresh mixed coniferous forests. Scots pine wood from Zielona Góra Forest (western Poland) characterised with the highest density, while from the Knyszyn Primeval Forest (eastern Poland)− with the lowest.
