Opis:: Influence of pine wood sawing technology on material efficiency indicators Coniferous wood processing is one of the basic methods of using natural wood resources. The aim of the work was to determine the impact of the selection of wood cutting technology, which plays an important role in shaping the material indices, especially the volumetric efficiency index. In the case of pine wood processing, group and individual technologies were assessed.. The use of frame saws guarantees the achievement of repeated sorting’s with a quantitative efficiency rate of 69%. The introduction of individual technology based on band saws results in an increase in quantitative sawing efficiency to 72%. The selection of processing technology and the dimensional structure of processed roundwood have a significant impact on the average sawing rate.
Wpływ technologii przetarcia drewna sosnowego na wskaźniki wydajności materiałowej. Przeroby drewna sosnowego odgrywają zasadniczą rolę w obszarze racjonalnego wykorzystania naturalnych zasobów surowca drzewnego. Drewno sosnowe stanowi dominującą grupę surowca odnawialnego na terenie Europy Środkowej. Dobór technologii rozkroju surowca drzewnego odgrywa znaczącą rolę w kształtowaniu wskaźników materiałowych a szczególnie wskaźnika wydajności ilościowej. W przypadku przerobów drewna iglastego dominujące są technologie grupowe oraz indywidualne. Zastosowanie pilarek ramowych gwarantuje uzyskanie powtarzanych sortymentów o wskaźniku wydajności ilościowej rzędu 69% wprowadzenie technologii indywidualnej opartej na pilarkach taśmowych skutkuje zwiększeniem wydajności ilościowej przetarć do poziomu 72%. Znaczny wpływ na średni wskaźnik przetarcia posiada dobór technologii przerobu oraz struktura wymiarowa przetwarzanego drewna okrągłego.

Opis:: The aim of this study was to determine direction, rate and character of the changes in coniferous forest communities caused by anthropogenic stress factors (alkaline emission and imission) changing with time. To fulfil this goal, we have performed comprehensive studies of soils and plants at the study sites located in coniferous forest communities remaining under direct influence of cement and lime industry in the Świętokrzyskie Voivodeship. There were differences in the accumulation of elements in pine needles collected at alkalized sites in comparison with needles from the control site: Ca content was 2.5 times higher and Cu, Pb and Sr contents were 2–3 times higher, while Al and Fe, and Mn contents were twice and 10 times lower respectively. SEM analysis of morphological features of pine needle surface, in particular degree of preservation of epicuticular waxes can be as an indicator of assimilatory organ degeneration caused by dust deposition which induces wax layer erosion. Declining species number and biodiversity, particularly conspicuous at the Sitkówka site, was a general tendency observed over the study period (from 18 to 10 years). Other noticeable processes include slow regenerative changes of the community with a tendency towards higher contribution of acidophilic coniferous forest species with lower light and temperature requirements and suppression of meadow, ruderal and associated taxa. Further studies are required in order to define succession rate and direction of changes in species composition of these communities.

Opis:: This study describes the effect of watering on the mycorrhizal development and growth of Scots pine seedlings in a bare root nursery. Seedlings of Scots pine, grown under nursery conditions on natural soil (loamy sand) and soil + litter, were subjected to two different watering regimes for five months. During this time, measurements of soil water potential were made. Seedlings grown in natural soil and subjected to drought conditions were of significantly greater shoot height and volume and they had one mycorrhizal morphotype more than watered seedlings. However, irrigated seedlings subjected to excessive watering possessed greater mycorrhizal colonization: 46% on natural soil and 72% on soil + litter, while non-irrigated seedlings had 36% and 67% levels of mycorrhizal colonization, respectively.

Opis:: Geobotanical studies of the resource lingonberry Vaccinium vitis-idaea L. of different-aged communities of the pine forest with mosses on the territory of the nature reserve “Grodnenskaya Pushcha” (Belarus) have been carried out. A linear relationship was found between the yield of V. vitis-idaea shoots (air-dry weight) and the projective cover r = 0,85; productivity (g/m 2) = –3,03253 + 1,79386* projective cover (%), (r 2 = 0,73)). The mode of illumination, moisture, and soil acidity affects the resource-cenotic parameters of V. vitis-idaea quite strongly (η 2 ± mn 2 = 51,3 ± 8,3 – 99,8 ± 0,1%). However, the linear dependence of the parameters on the factors was either not revealed or low (up to r = 0,38). This indicates a non-linear relationship (k > 4,0) of the studied parameters of V. vitis-idaea with abiotic environmental factors, which is formed under conditions of interspecific competition and ecological mosaicism of phytocoenoses. A positive relationship was recorded at low values of the projective cover between the blueberry V. myrtillus L. (up to 20%) and V. vitis-idaea (up to 5%), which indicates a positive relationship of these species in the phytocoenosis with their low abundance.

Opis:: 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.

Opis:: We investigated the phenotypic variation of five morphological needle characters of Scots pine (Pinus sylvestris L.) in three populations. Two of the populations occurred in bogs and the third one formed a degraded fresh pine forest showing some features of a dry pine forest. The greatest variation was found in characters a (needle length), b and d, denoting the number of stomatal rows respectively on the convex and flat sides of the needle. Conversely, characters c and e (average number of stomata per 2 mm of needle length on the convex and the flat side of the needle) were stable, with little interindividual variation. The two bog populations and the dryland population exhibited different sets of character correlations. The interpopulation differentiational detected on the basis of morphological character expression was markedly influenced by both the different edaphic conditions, and the distinct genetic structure of the studied populations.

Opis:: Incidence of Armillaria root disease and the population structure of associated Armillaria spp. were studied in 5-17-year-old Scots pine plantations in west-central Poland. Two infection centres (1.14– 9.30 ha) in each of three forest districts (Siemianice, Zielonka and Złotów) were intensively sampled. Root collars were examined for mycelial fans, decayed wood, and rhizomorphs. Twenty two isolates of Armillaria ostoyae collected from epiphytic rhizomorphs from 20 living and two dead trees in the six infection centres were identified with somatic incompatibility group. Only one somatic incompatibility group for A. ostoyae was found. Twenty one isolates produced rhizomorphs on oak-wood discs submerged in a sand-forest soil substrate. Isolates from Siemianice formed the smallest rhizomorph networks and those from Złotów the most abundant. There were 16 different genets among 22 isolates of A. ostoyae distinguished by RAPD analysis. Genetic similarity among genets was 25.6–97.5%. The large diversity in A. ostoyae suggests that sexual reproduction may occur in nature more often than expected.

Opis:: The paper presents the results of an analysis of the influence of soil bulk density in a forest nursery plot on the growth and quality parameters of Scots pine and European beech seedlings. Particular density variants were obtained using a tractor device exerting controlled pressure on the soil, while field examinations were performed on an area of ‘Kłaj’ forest nursery in Niepołomice Forest District. Three series of plots were prepared for each species, applying a unit pressure of the values of 50, 100, 150, 200, 250 kPa, corresponding to the dry bulk density in the range of 1.03-1.19 g cm-3, and control plots without the pressure. Seeds of the examined species were sown on the prepared plots, and after 6 months of growth the seedlings were subjected to biometric analysis determining differentiation in root neck diameter, length of the above-ground part and root system, as well as dry mass of particular parts of the plant. The quality of the seedlings was also determined using the method of Schmidt-Vogt. The results obtained show that the change in dry bulk densitysoil significantly affected most of the growth parameters of theexamined seedlings. Especially high negative correlations were obtained for the length and dry mass of the root system. A significant influence of dry bulk density variant on all growth parameters of Scots pine seedlings, and on some parameters of European beech was demonstrated. An increase in soil bulk density clearly caused also a deterioration of European beech seedlings quality.
