    Opis:
    The radiation exchange drives the plant ecosystems energy balance and provides the energy for photosynthesis, transpiration and plant growth. The investigation on net radiation and its component during vegetation season in relation to the clearness index and sun elevation in a cultivated 31-year-old mountain spruce [Picea abies (L.) Karst.] stand is presented. Downward short-wave radiation – Sd (incident on the spruce stand was the main part of the short-wave radiation balance during the whole growing season (April–October) 2008. The Sd a mount i s seasonally variable factor determined by the duration of solar shine and the atmosphere transmissivity. Obtained value of net radiation (Rn) and downward short-wave radiation (Sd) ratio amounts to 0.61 on average during the growing season 2008 documenting the importance of the downward short-wave radiation in the net radiation of investigated spruce stand.

    Opis:
    The paper presents the results of the research on the accumulation of nutrients and heavy metals in needles and bark of Picea abies and Picea omorika. In this research, the age of the needles and the content of the examined components in the soil were taken into account. The research was conducted within the area of the forest at the University botanic garden in Košice (Slovakia). The little acidification of the soil that was found under the spruce crowns slightly changed with the depth (0.0–0.2 m, 0.2–0.4 m, 0.4–0.6 m). Under the stand of P. abies, a lower content of organic matter was demonstrated, than under the trees of P. omorika. The tested soil samples were low in nitrogen, phosphorus and calcium, and sufficiently rich in potassium and magnesium. The spruce needles were dominated by macroelements, and their concentrations varied depending on age and species. Both P. abies and P. omorika needles were acidic, with 1-year-old needles showing higher acidity. Low nitrogen content in the needles of the studied spruce was found, and the N:P ratio did not exceed 3.5. Statistically significant differences were found in the content of N, K, Ca, Zn, Mn, Fe, Ni, Cu and Cd in 1-year-old needles and pH, N, P, Ca, Zn, Mn, Fe, Ni, Cu and Cd in 2-yearold needles of spruces. The results also indicate that the bark of the studied spruce is acidic, with pH values of 4.70 (P. abies) and 4.15 (P. omorika). The P. abies bark accumulates higher amounts of Mg, Ca, Ni, Cu and Mn, and the P. omorika bark accumulates more N, P, K, Zn, Fe and Cd. The research indicates that both spruce species barks are suitable for comparative studies on bioindication of environment quality.

    Opis:
    The results of previous studies have shown high breeding values of Beskidian spruce. The aim of the study was to assess the genetic structure of seventeen Norway spruce provenances from the Beskidy Mts. tested in IPTNSIUFRO 1964/68 experiment in Krynica, which survived after massive wind damage on the plots. Polymorphism of five isozyme systems encoded in five loci was determined. The highest value of genetic diversity parameters: mean number of alleles per locus and observed heterozygosity was noted for progeny of spruce from the Eastern Beskidy Mts. (Na = 1.47, Ho = 0.15), and the lowest – for the provenance from the Western Beskidy Mts., Babia Góra massif and the Beskid Sądecki Mts. (Na = 1.27, Ho = 0.12). Mean genetic distance between analyzed spruce provenances was equal to 0.027.

    Opis:
    The aim of this study was to simulate transformation of species composition, biomass and number of treesin spruce stands depending on a possible combination of cutting and planting scenarios as well as climate changes. The FORDRY computer model was used to predict the dynamics of Norway spruce (Picea abies (L.) Karst.) stands in Nadsyansky Regional Landscape Park in the Ukrainian Carpathians. Potential changes in species composition, biomass and number of trees were forecasted for the next 50 years. Four scenarios, first – warm-dry, second – cutting dead spruce trees, third – cutting all trees andfourth – planting, were compared to the control one. The analysis revealed a rapid decrease of stand biomass in the first decade as a result of spruce decline. The model predicts an increase in beech biomass before the 50th year of simulation in all scenarios. In the planting scenario, the biomass of beech increased up to 199.9 ± 6.9 t·ha-1 in the 50th year. Correlation analysis showed weak autocorrelations of spruce and negative cross-correlations of spruce with the total stand in control and other scenarios. The output of performed simulations is supported with field and literature data. Results of this study can be applied in the long-term planning of the management and conservation activities in this region. The application of FORDRY model was found useful for analysing the potential scenarios of spruce stand transformation in Nadsyansky Regional Landscape Park.

    Opis:
    The experimental plots were located in the middle forest zone (900– 950 m) on two nappes of the flysch Carpathians: Magura (the Ujsoły Forest District) and Silesian (the Wisła Forest District) in the spruce stands of age class 21– 40 years. Serpentinite was introduced in the autumn of 2008 on all plots while other fertilizers (N, P, NP and NPK) in the spring of 2009. Based on the chemical composition of soil solutions collected in lysimeters placed at the depth of 20 cm in the autumn 2008 and the spring and autumn 2009, ecochemical parameters were calculated: acid neutralization capacity (ANCaq), alkalinity (ALK), the degree of soil acidity (Ma%), acidic cations (Ma), saturation of the exchangeable complex of the soil solid phase (Mb) with alkalis, saturation with alkalis (BS), molar relations Ca/Al, Mb/Al, BC/Al. After the winter, soil solutions became acidic, especially in the Wisła Forest District. The saturation of the studied soils demonstrates moderate flexibility of soils in the Wisła Forest District in relation to acid load, and high flexibility of the Ujsoły soils. The opposite trend was observed for the degree of acidity of soils. Acid neutralization capacity and alkalinity of the waters showed significant variations in soil pH even in the case of small variations in the composition of the solution, if they were caused by the inflow of the anions of NO3 - and SO4 2-. After application of the fertilizers, an increase of Mg, Ca and Mb was noted in the soil solution, determined in the overlaying highly acidic organic horizons trough the ion-exchange buffering mechanism of highly protonated functional groups with high buffering capacity. Highly improved content of Mg in a soil, and in some cases – also the content of N, P and K, present potential improvement of forest growth capacity without the hazard of adverse side-effects of liming. Aluminum stress in the spruce is unlikely, while trees in the control plots in the Wisła Forest District may already be sensitive.
