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.

Tytuł:: Effect of increased nitrogen depositions and drought stress on the development of young Norway spruce Picea abies (L.) Karst. stands

Opis:: The effects of drought stress, stress by increased nitrogen depositions and the combined effect of the two stress factors on the growth of Norway spruce Picea abies (L.) Karst. were studied in two stands. The drought stress was induced by reducing atmospheric precipitations by 60% and the increased nitrogen depositions were simulated by repeated applications of ammonium sulphate at a rate corresponding to 100 kg N ha–1 year–1. All stress factors under study affected the height increment of the above-ground part, the length and colour of needles, and the biomass, vertical distribution, functionality and mycorrhizal infection of fine roots. The root system responded to the simulated stresses right from the the very first year of their action, exhibiting a greater damage than the above-ground part of the plant. Drought acted as a stress factor stronger than the nitrogen depositions themselves. The strongest impact was recorded in the simultaneous influence of the stress factors.

Tytuł:: Sustainability of Picea abies of Istebna provenance in Dupniański Stream catchment as dependent on stand age class

Opis:: Ecochemical indexes such as soil buffer reaction (pH), acid neutralising capacity (ANCaq), alkalinity (ALK), soil acidity (Ma%), basic cation saturation (BS), and molar ratios Ca:Al and BC:Al were used to study the sustainability of Norway spruce of Istebna provenance in stands differing in age class. The data were obtained from the research conducted in the Dupniański Stream catchment in the Silesian Beskid Mts. (Poland). The acid neutralising capacity, alkalinity, and soil acidity were found to depend on the age of spruce stands. The increased acidification of deposits was due to the presence of sulphate and nitrate ions which were washed out from the surface of plants. Passing through the canopy caused a decrease in the acid neutralising capacity, alkalinity, and base cation saturation, and an increase in the soil acidity, with the values being dependent on stand age. The soil acid reaction shifted to the range of the aluminium and iron bufferness, but the Ca:Al and BC:Al ratios were still above the level when aluminium stress is probable. The washout of the basic cations beyond the spruce root system, and the low levels of exchangeable Mg2+ and Ca2+, basic cation saturation of soil water, and effective base saturation of soil may affect the vitality and health of spruce stands in the future. To maintain the sustainability of Norway spruce stands of Istebna provenance in the Dupniański Stream catchment it is necessary to increase the retention of basic elements, especially Mg2+ and Ca2+, by means of stand conversion or fertilisation.

Opis:: In the present study we analysed the mitochondrial intraspecific variation in natural populations of Norway spruce. We used the second intron of the nad1 gene, which contains two polymorphic short tandem repeats. Due to the maternal inheritance of mitochondrial DNA in Norway spruce, the spatial distribution of haplotype DNA allows insights into seed dispersal and artificial seed transfer. A total of 504 trees distributed all over Austria were genotyped, and 9 different haplotypes could be found. A geographical map of the haplotype variation pattern of Picea abies is presented.

Opis:: The paper describes the measures adopted by the Czech State Forests for the conservation and reproduction of the Norway spruce gene pool in the Moravian-Silesian Beskid Mts. In addition to the assurance of natural regeneration in genetically valuable stands and the use of high-quality autochthonous stands as seed sources for artificial regeneration, the measures include selection of plus-trees, establishment of seed orchards, seed stands and clone archives, and identification of gene pools. Seeds of the most valuable regional populations are deposited in a seed bank.

Tytuł:: Potential for genetic conversion of Norway spruce Picea abies (L.) Karst. stands and methods for preserving gene resources of Istebna race in Silesian Beskid Mts

Opis:: The forests of the Silesian Beskid Mts have a specific composition with a marked dominance of Norway spruce. Although spruce stands are seriously threatened, some of them, such as those of Istebna race, show excellent genetic value. The work stresses the need for the conversion of spruce stands in the Silesian Beskid range on the basis of population genetics and describes the principles of such conversion.
