There were formulated two general approaches to the problem under consideration indicating the experimental data sources. Mathematical symbols were introduced to denote each plant part and describe its function. There was constructed a discrete two – dimensional dynamical system that depicted Scots pine growth process followed by making suitable assumptions on its components. It has been found that this system is an iteration sequence of certain area transformation which served as the basis for the dynamical system development. Consequently, several important results like theorems, comments and charts were obtained. The obtained research results are related to variations of total dry weight Mn that grows exponentially, while linearly for n large enough. It was also demonstrated that the proportion of assimilatory to non assimilatory parts λ ̅ tends to the calculated stationary point λ1.

Sformułowano dwa ogólne podejścia do rozważanego problemu, sygnalizując źródła danych eksperymentalnych. Wprowadzono symbolikę matematyczną dla każdej części rośliny i podano, jakie pełni funkcje. Skonstruowano dwuwymiarowy dyskretny układ dynamiczny opisujący proces wzrostu sosny zwyczajnej i poczyniono odpowiednie założenia odnośnie jego składowych. Zauważono, że układ ten jest ciągiem iteracji pewnego przekształcenia płaszczyzny, na bazie którego został utworzony układ dynamiczny. Dzięki niemu uzyskano kilka istotnych wyników w postaci twierdzeń, uwag i wykresów. Uzyskane wnioski dotyczą zachowania się całkowitej biomasy Mn, która rośnie wykładniczo, a dla dostatecznie dużych n rośnie liniowo. Wnioski opisują również stosunek biomas λ ̅, który dąży do obliczonego punktu stałego λ1.

Provenance trials were designed to analyse the quantitative responses of tree species to environmental variables found in different experiment location. However, we have still limited knowledge how natural and artificial selection affects genetic variation of the species populations gather in such experimental sites. We have used bulked DNA-based RAPD and ISJ analysis to investigate genetic diversity and differentiation of Scots pine populations from two Polish locations of IUFRO 1982 provenance trial placed in Kórnik and in Supraśl. Applied categories of DNA markers differed in terms of revealing genetic diversity of the species. Ten RAPD primers applied in the study yielded a total of 75 bands, of which 21 (28%) and 15 (20%) were polymorphic in Kórnik and in Supraśl, respectively. Six ISJ primers revealed 42 bands of which 4 (9.52%) and 14 (33.3%) were polymorphic in Kórnik and in Supraśl, respectively. The genetic diversity and differentiation was low, as expressed by He=0.071 and He=0.085, and by genetic distance values which ranged from 0.0 to 0.240 (on average 0.081) and from 0.017 to 0.188 (on average 0.094) for Kórnik and Supraśl, respectively. Location of provenance trial appeared to have a significant influence on revealed level of genetic polymorphism and pattern of interpopulation differentiation. However, genetic structure found for analysed Scots pine provenances from IUFRO 1982 in Kórnik was also confirmed for Supraśl experimental site. In the light of available data we also discussed the influence of historical migration routes and gene flow on observed genetic variation of the species.

The pinewood nematode (PWN), Bursaphelenchus xylophilus, is the causal agent of pine wilt disease (PWD). This nematode is considered to be an indigenous to North America and was introduced to Japan in the late 19th century. Subsequently, it has spread throughout Japan and in many other countries, China, Taiwan, and South Korea. In 1999, B. xylophilus was discovered in Portugal, and in 2008 in Spain. So far the studies have revealed that the pathogenicity of B. xylophilus varies between different isolates. The conducted study compared the pathogenicity of five isolates of B. xylophilus, originating from different parts of Japan, to 3-year-old Pinus sylvestris, and their ability to reproduce in the seedlings. The results revealed diverse virulence of B. xylophilus resulting in plant mortality. Three isolates S10, Ka4, and T4 caused 100% mortality of plants within three months while at the same time, the other two isolates, C14-5 and OKD-1 did not cause any disease symptoms on plants. After seven months, some dieback occurred on two seedlings, but similar symptoms were also found on the control plant. Moreover, a significant positive correlation was found between nematode virulence and the number of nematodes reproducing on pine seedlings.

Forests play a very important role in the process of the carbon cycle in the natural environment and timber harvesting disturbs the natural circulation of this element considerably. Moreover, the way of handling the post clear cutting residues can also influence the accumulation of carbon in the soil. Usually, increased contents of organic carbon in the near-surface layers of mineral forest soils were observed in the first year following the stand removal. The greatest soil carbon enrichment was recorded when branches were ground and mixed with the mineral soil. Considerable variations in the observed contents of organic carbon in the near-surface layer of mineral soils during the first two years after clear cutting and later makes it impossible to indicate the most advantageous method of management of post clear cutting residues.

Lasy odgrywają bardzo ważną rolę w procesie obiegu węgla w przyrodzie. Pozyskanie drewna w znaczący sposób zakłóca obieg tego pierwiastka. Także sposób postępowania z pozostałościami zrębowymi wpływa na kumulację węgla w glebie. Wzrost zawartości węgla organicznego w przypowierzchniowej warstwie mineralnej gleb leśnych następował zazwyczaj w pierwszym roku po usunięciu drzewostanu. W największym stopniu wzbogacenie gleb w węgiel następowało po rozdrobnieniu gałęzi i wymieszaniu ich z glebą mineralną. Duże zróżnicowanie zawartości węgla organicznego w przypowierzchniowej warstwie mineralnej gleb, w okresie dwóch lat i późniejszym po wycięciu drzewostanu, nie pozwala wskazać najkorzystniejszego sposobu zagospodarowania pozostałości zrębowych.
