Opis:
The influence of slope exposure and altitude on the height of trees in the stands of the Carpathian beech forest Dentario glandulosae-Fagetum in the lower montane zone in the Bieszczady National Park. The aim of the study was to investigate the influence of slope exposure and elevation above sea level on the average height of trees in the stands of the Carpathian beech forest Dentario Glandulosae-Fagetum in the lower montane zone of the Bieszczady National Park. The research material consisted of measurements made as part of a grid of permanent research plots of the Bieszczady National Park with a size of 4 ares, arranged in a grid of squares with a spacing of 500 x 500 m. Using a two-factor analysis of variance, the average height of beech trees in two height zones (600-800 and 800-1000 m above sea level) and at two slope exposures (north and south) were compared. The influence of the interaction between the two factors was also studied. The height of beech stands was mainly determined by the altitude and the interaction between the exposure of the slope and the altitude. It was not found that the exposure of the slope significantly differentiated the average heights of beech trees in the lower montane zone in the Bieszczady National Park.
Wpływ ekspozycji stoku i wysokości nad poziomem morza na wysokość drzew w drzewostanach buczyny karpackiej Dentario Glandulosae - Fagetum w reglu dolnym na terenie Bieszczadzkiego Parku Narodowego. Celem pracy było zbadanie wpływu ekspozycji stoku oraz wysokości nad poziomem morza na średnie wysokości drzew w drzewostanach buczyny karpackiej Dentario Glandulosae - Fagetum w reglu dolnym na terenie Bieszczadzkiego Parku Narodowego. Materiał badawczy stanowiły pomiary wykonane w ramach siatki stałych powierzchni badawczych Bieszczadzkiego Parku Narodowego o wielkości 4 arów, rozmieszczonych w siatce kwadratów o więźbie 500 x 500 m. Za pomocą dwuczynnikowej analizy wariancji porównano średnią wysokość buków w dwóch strefach wysokości (600-800 i 800-1000 m n.p.m.) oraz przy dwóch ekspozycjach stoku (północnym i południowym). Zbadano również wpływ interakcji między tymi dwoma czynnikami. Wysokość drzewostanów bukowych była determinowana głównie przez wysokość n.p.m. oraz interakcje między eskpozycją stoku a wysokością nad poziomem morza. Nie stwierdzono by ekspozycja stoku istotnie różnicowała średnie wysokości buków w reglu dolnym w Bieszczadzkim Parku Narodowym.

Opis:
The article describes horizontal structure of the tree layer, natural regeneration, snags and crown projections of natural beech stands on three permanent research plots in the wide altitudinal range in the Krkonoše Mts (Czech Republic). The spatial structure was classified from 1980 to 2010 and subsequently the prediction of spontaneous development with an outlook for 30 years (to 2040) was done by growth simulator. Hopkins-Skellam index, Pielou-Mountford index, Clark-Evans index and Ripley’s K-function were calculated. Further, the vertical structure and total diversity index was evaluated. The horizontal structure of individuals in the tree layer had not changed significantly during the monitored years. Tree spatial pattern of the lowest altitude lying herb-rich beech forest was mostly regular to random, in acidophilous mountain beech forest predominantly random and in fragments of beech groups around the timberline aggregated. Juvenile growth on all investigated plots was distributed aggregated and snags randomly. The horizontal structure of crown projection centroids had always higher values toward the regularity than tree layer and was random to regular. The result of principal component analysis also confirmed that spatial pattern was dependent on the altitude, but also on the number of trees.

Opis:
The study deals with long-term dynamics of snags and fallen dead wood from 1970 to 2010 in an unmanaged forest ecosystem dominated by European beech in the Bažinky area, Krkonoše National Park (Czech Republic). The volume of dead wood was estimated from 1970 separately for fallen dead wood (logs) and standing dead wood (snags and stumps). Total dead wood volume on permanent research plot (PRP) 6 increased from 41.9 to 241.6 m3 ha–1 and on PRP 7 from 27.7 to 170.0 m3 ha–1. During 40 year case study the mean total volume of fallen dead wood was 193.3 m3 ha–1 (± 29.8 S.E.) and 96.2 m3 ha–1 (± 19.4 S.E.) and the mean total volume of standing dead wood was 17.4 m3 ha–1 (± 3.4 S.E.) and 12.6 m3 ha–1(± 1.4 S.E.) on PRP 6 and PRP 7, respectively. Comparing tree species, the mean volume of fallen dead wood was significantly higher for Norway spruce than for beech in the decomposition class 1 (F(1, 14) = 5.7, P = 0.03) and significantly higher for beech in the decomposition classes 4 (F(1, 14) = 20.4, P < 0.001) and 5 (F(1, 14) = 25.5, P < 0.001). Dead wood was distributed from randomly to aggregated spatial pattern. Despite the rapid decay of beech wood, the amounts of deadwood are likely to increase further during the next decades with continuing disintegration of the forest stand.

Opis:
The results of research into leaf stomatal variability of five European beech provenances originating from Austria, Bosnia and Hercegovina, Germany, Romania and Serbia are presented in this paper. Aim of the study was to investigate how stomatal traits of provenances originating from different environments change in response to drought stress and to assess the phenotypic plasticity of the stomatal features investigated. The study was conducted during two different years, characterized by contrasting weather conditions (2010 and 2011). Two-way ANOVA revealed that provenances differ significantly in terms of stomatal density (SD), width of stomatal aperture (Wb), potential conductance index (PCI) and relative stomatal pore surface (RSPS), during both seasons. In a dry year (2011) all provenances significantly increased stomatal density by between 16.1% (Hasbruch – DE) and 21.9% (Cer – SRB). Guard cell length (LA) was not statistically different among provenances in either year (2010 and 2011), even though LA decreased in the dry year (2011) in all provenances. Reaction norms were steep in most of the parameters suggesting the possibility of a plastic response of provenances toward changes in soil water regime, influenced by the prevailing weather each year. Phenotypic plasticity indices were the highest in regards of SD, PCI and RSPS, indicating that these traits would be good candidates for improvement in breeding programs aimed at selection of drought resistant.

Opis:
The study presents the results of investigation on reaction of beech (Fagus sylvatica L.) leaves observed next year after planting seedlings in different positions in a young spruce stand located in upper mountain conditions. The methods of chemical analyses and assessments of chlorophyll fluorescence were applied with the aim to evaluate a course of leaf adaptation. In the young spruce stand located in the Karkonoše Mts, bare root beech seedlings after cultivation in full light were planted into three main positions to spruce trees (under the crown, within crown perimeter and in stand gaps). Next year after planting, the total biomass, leaf nutrient content and chlorophyll fluorescence parameters were evaluated. The beech trees planted under spruce (Picea sp.) crowns had significantly lower specific leaf mass and the mean leaf area was decreasing from shade to sun. Differences in nutrient contents were not significant between the treatments. We found significantly higher values of minimal (F0) and the maximum fluorescence (Fm) as well as of the maximum quantum yield of PSII photochemistry (Fv/Fm) in the leaves of beeches growing under the spruce crown. Significant differences among treatments were found also in the courses of the values of maximum fluorescence yield Y(II) and nonphotochemical quenching (NPQ). Our study indicated that bud forming processes are only partially responsible for physiological properties of beech leaves evaluated next year after planting. Photosynthetic performance is also influenced by actual growing conditions. A great part of acclimation occurs already in the first year after planting (change of the light conditions). We speculate that this phase of gradual acclimation of the assimilation apparatus can be one of the reasons of physiological weakening of the plant after planting to different light environment.

Opis:
The studies were carried out in 12 beech stands, growing on mountain fresh forest site in Magurski National Park. Stands differed in respect of exposition (northern and southern) and age - lower age classes (21-60 years old) and higher age classes (81-120 years old). This paper presents evaluation of frequency of disease symptoms occurrence in the crowns and on the trunks of beeches. The presence and the place of occurrence of fungus Ascodichaena rugosa and insects Cryptococcus fagisuga and Ectoedemia liebwerdella, which could be connected with beech bark necrosis on the trunks were noted down. In each stand 50 trees, growing side by side in center of the stand, were analyzed. Among 600 analyzed trees of Fagus sylvatica, 2.6% had a dead top. Crown thinning were present on 51.8% of trees. It appeared frequently in higher age class stands and didn’t cover more than ¼ of the crown. Moreover, in crowns of 4.1% of trees the leaf chlorosis appeared. The most frequent symptom on trunks of beeches were local necroses (98% of trees), that were sometimes connected with slime fluxing (3.3%). Necroses were the most number in stands growing on the southern exposition and on south parts of the trunks. Cryptococcus fagisuga appeared mostly in high age class stands. Intensity of its appearance was similar on the trees growing on the southern and northern exposition (respectively, 48.3% and 53.3%). Particular parts of the trunks were colonized with similar frequency by C. fagisuga irrespective of cardinal points (N-29.3%; S-21.7%; W-22.7%; E-26.2%) and number of necroses on the trunks. Ascodichaena rugosa appeared on 8.6% of trees, more frequently on their north parts of the trunks (7.3%). In the places colonized by fungi A. rugosa, insect C. fagisuga was absent. Occurrence of larvae of Ectoedemia liebwerdella was mostly found on trunks of beeches growing on the southern exposition (43.0%), on 35.3% of trees they colonized south parts of trunks. There wasn’t observed any connection between the occurrence of these larvae and symptoms of local necroses.
Badania przeprowadzono w 12 drzewostanach bukowych, rosnących na siedlisku lasu górskiego świeżego w Magurskim Parku Narodowym. Drzewostany różniły się wystawą (północna i południowa) oraz wiekiem - wyróżniono drzewostany młodszych klas wieku (21-60 lat) i starszych klas wieku (81-120 lat). Celem pracy była ocena częstotliwości występowania symptomów chorobowych w koronach drzew i na pniach buków. Odnotowywano również obecność oraz miejsce usytuowania na pniach grzyba Ascodichaena rugosa oraz owadów Cryptococcus fagisuga i Ectoedemia liebwerdella mogących mieć związek z nekrozami kory buka. W każdym drzewostanie analizie poddano 50 drzew, rosnących obok siebie w części środkowej drzewostanu. Wśród 600 zbadanych drzew Fagus sylvatica, u 2,6% stwierdzono martwy wierzchołek. Przerzedzenie korony wykazywało 51,8% drzew. Częściej stwierdzano je w drzewostanach starszych klas wieku, lecz na ogół obejmowało nie więcej niż ¼ stanu ulistnienia. Ponadto w koronach 4,1% drzew wystąpiło chlorotyczne przebarwienie liści. Najczęstszym objawem na pniach buków były lokalne nekrozy (98% drzew), które niekiedy były połączone z wyciekami śluzu (3,3%). Nekrozy najliczniej występowały na południowych stronach pni oraz w drzewostanach rosnących na wystawie południowej. Cryptococcus fagisuga występował głównie w drzewostanach starszych klas wieku. Nasilenie jego występowania było podobne w drzewostanach rosnących na wystawie południowej i północnej (odpowiednio 48,3% i 53,3%). Poszczególne partie pni owad ten zasiedlał ze zbliżoną częstotliwością niezależnie od strony świata (N-29,3 %; S-21,7%; W-22,7%; E-26,2%), oraz od liczby nekroz występujących na pniach. Grzyb Ascodichaena rugosa występował na 8,6% drzew, częściej na północnych stronach pni (7,3%).W miejscach zasiedlenia pni przez A. rugosa nie występował czerwiec C. fagisuga. Oznaki minowania kory przez larwy Ectoedemia liebwerdella występowały głównie na pniach buków rosnących na wystawie południowej (43%), zajmując głównie południowe ich strony (35,5%). Nie stwierdzono zależności pomiędzy minowaniem kory przez te larwy a występowaniem lokalnych nekroz.

Opis:
Productive European beech stands (Fagus sylvatica L.) involving Scots pine (Pinus sylvestris L.) are formed in Ukrainian Roztochie. Considering value and limited distribution of beech stands involving pine in tree species composition, it is necessary to work out and implement measures for their natural restoration in connection with the climate change and the efficient use of raw materials and non-wood products. Main forestry and management indices of beech stands that include pine in tree species composition were analysed. Forestry activities that are currently carried out in middle-aged and maturing stands significantly reduce their relative completeness and growing stocks, as determined by comparing growth particularities of productive beech stands from different sources.

Opis:
In autumn 2006, i.e. in the 5th year from the culture establishment, and when the tree growth had finished, on each culture we measured tree height, height increments in the years 2004−2006 and root collar diameters. We also noted the presence of the main shoot and top bud on the main shoot, size and color of the assimilative apparatus and determined the survival rate of the seedlings. The assessed and measured features allowed for determination of the seedling quality and vitality. Mean values of all features were calculated for plots and their groups, distinguished on the basis of their belonging to particular forest districts and regions as well as basing on the presence or absence of stand protection and in regard to stand disintegration. The results indicate the poor condition of parts of the cultures with beech. Generally, the quality and vitality of the seedlings was assessed to be average, with a smaller or larger tendency towards the decrease. This points towards difficulties in performing stand regeneration and in varying their composition in the higher locations of the Beskid Śląski and Żywiecki Mts., which experience extreme climatic conditions. This was observed particularly on height and quality parameters worsened along with an increase in a degree of stand disintegration. Many beech seedlings grew better on the fenced plots than on the unfenced ones, which indicates positive results of the protection of cultures against game and justifies their fencing.

Opis:
Beech (Fagus sylvatica L.), oak (Quercus robur L.) and pine (Pinus sylvestris L.) wood were volume-densified by means of thermo-mechanical modification. At first stage the wood was heated in a hydraulic press at temperature 100°C for 720 s, and then one-step densified in order to obtain the target thickness. The wood was cooled in a hydraulic press with unheated plates. Density profiles parallel and perpendicular to the grain were examined. The analysis of the density profiles was carried out on the basis of the following parameters: mean density, minimum to mean density ratio, maximum density, and the distance between the maximum density area and the wood surface. Wood hardness was determined according to the Brinell method. Volume-densified pine wood was characterized by considerably lower susceptibility to densification than beech or oak wood. Densified beech wood had the highest mean density 921 ±7 kg/m3, and the highest maximum density 968 ±12 kg/m3. The Brinell hardness of densified beech, oak and pine wood was twice as high as before the densification. The greatest hardness after the densification 78.60 ±10.56 N/mm2 was observed in beech wood.

Opis:
Investigations were conducted on the strongly infested by microbes embryos isolated from seed stratified in non-sterile conditions or from tree buds. The results showed, that PPM (Plant Preservative Mixture, produced by Plant Cell Technology, Inc.) was very useful for increasing the percentage of sterile cultures disinfected in a 5% solution of NaOCl. The best way of applying PPM turned out to be adding the substance directly to the growing medium. At the concentration of 2 or 4 cm3 x dm-3 of PPM there was an 30% increase in percentage of sterile of in vitro cultures developed from embryos and 70-80% of cultures developed from buds, as compared with the control without PPM. At the range of concentrations employed in this study, no negative effects of PPM upon the development and growth of callus were observed.

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.

Opis:
The study focused on tree rings of European beech in the stands in the Iława Forest District. The aim of the study was to analyse the effect of climatic conditions on the formation of the annual ring width at the limits of beech natural distribution in an area where the Atlantic and Continental climate meet and overlap. The mean tree−ring width was relatively wide and equalled 2,89 mm. The obtained time series covered the years between 1900 and 2002. On the basis of the response function analysis and indicator years it was demonstrated that there was a considerable impact of spring/summer precipitation on annual growth ring formation.

Opis:
The aim of this study was to examine the effects of pruning the root system and different doses of nitrogen fertilization on the height and root collar diameter of 2-year-old beech seedlings (Fagus sylvatica L.). This research was conducted in the forest nursery Muchów (Jawor Forest District, regional directorate of State Forests in Wrocław) and two different pruning treatments (no pruning and at 12 cm depth) and nitrogen fertilization doses (25 and 50 kg×ha-1) were applied. Results from an ANOVA showed statistically significant differences between the two pruning treatments (p=0.000) as well as for the interaction of both treatment factors (p=0.019). Root collar diameter correlated with seedling height, both of which were significantly different for the two pruning treatments (p=0.000). No statistically significant impact by the nitrogen fertilization doses on seedling height could be observed (p=0.125). To conclude, we found that it is reasonable to reduce the doses of nitrogen fertilization to half the recommended amount, 25 kg×ha-1, if the root system is not pruned during the second growth year. Seedlings that do receive pruning should be fertilized using the recommended nitrogen doses.

Opis:
All basic components of the water budget of a mature spruce and beech stand in the Orlické Mts are quantified and the results are given in summary tables. Rest periods (November–April) and vegetation seasons (May–October) are evaluated separately. Special attention is paid to the measurement of snow cover and the processes of snow melting in both types of stands.
