Mineral status of plants and soil in silver fir stands of the Silesian and Żywiec Beskidy (Western Carpathians)

Abstract. For last decades the Silesian and Żywiec Beskidy have been affected by different types of anthropopression. Up to the nineties of the 20th century, forests of the area were affected by a high level of air pollutants transported mainly from the Upper Silesian and Ostrava industrial regions. From 2004 intensive felling and skidding works in declining forest stands combined with their reconstruction have been carried out. Among different species silver fir has been introduced on a large scale. In the paper the results of investigation of plants and soil carried out 7 sites located in Beskidy Mountains (49°41'6"N, 19°1'48"E) are presented. Contents of K, Mg, Ca and N in needles of silver fir (Abies alba Mill.) and leaves of bilberry (Vaccinium myrtillus L.) were determined which was accompanied by a chemical characteristics of forest topsoil from the same sites. Moreover, in both environment compartments, the concentration of S, Pb, Cd, and Zn was also determined to assess the level of anthropopression in individual sites. In general, the obtained results show relatively good mineral status of plants. Some disturbances in the ratios of elements in plants were found in sites located near the Polish and Czech border. In plants and soil in these sites an elevated level of heavy metals was found which testifies the transboundary transport of air pollutants. The bilberry seems to be a better bioindicator of heavy metal pollution than silver fir.

Needle age dependence of photosynthesis along a light gradient within an Abies alba crown

Age and shade effects on needle structure and photosynthesis were determined within a lower part of Abies alba crown along a horizontal increasing gradient of branches self-shading. It was hypothesized that a decrease in net CO 2 assimilation rate with increasing needles' age would be related to: (1) structural age-related changes in needles, (2) reduction of stomatal conductance, (3) nitrogen translocation from old to young needles, and (4) decrease in efficiency of photochemical processes. Leaf mass-to-area ratio increased non-linearly with needle age. In a needle cross section, distance between the vascular bundles decreased, and height of palisade parenchyma cells increased with age. The structural changes observed in our study might lead to an increase in internal resistance to CO 2 with greater needle age. Total needle nitrogen concentration linearly decreased with age due to dilution and/ or translocation to younger needles. When expressed per needle area, nitrogen content was reduced in 6-year-old needles compared with younger ones. Net CO 2 assimilation rate per needle area decayed and was accompanied by a decrease in transpiration and water and photosynthetic nitrogen use efficiency. Old needles maintained high photochemical efficiency which compensated to some extent for light deficit in their micro-light environments. Our results have suggested that there is a mechanism controlling the relation between efficiency of light and dark photosynthetic processes along the needle age and shade gradient in A. alba crown.Keywords Chlorophyll a fluorescence Á Leaf age Á Needle structure Á Nitrogen concentration Á Photosynthesis Á Silver fir

The aim of the presented research was to investigate the effect of three heavy metals - lead, cadmium and copper - on the callus cells of Abies nordmanniana. The toxicity degree and toxicity effect of the selected heavy metals was determined on the embryonic level. On the basis of the spectrometric analyses as well as macroscopic and microscopic observations, this research referred to the accumulation of heavy metals in tissues, assuming that this mechanism is related to the acquisition of tolerance by cells exposed to this type of abiotic stress. Moreover, the effect of the genotype of fir on the cell defence, that is, the induction of tolerance, was analysed. Understanding of the issues related to the heavy metal resistance of plant genotypes in future may contribute to the selection of genotypes of individuals that are more resistant to stress factors, particularly in the multi-directional and rational forest management. The results showed that lead (20 mg l-1), which proved to be the most toxic amongst the three examined heavy metals, has the most severe negative effects on the tissue of fir trees. Copper (20 mg l-1) was accumulated for a long time in the cells of fir trees, and it was not degraded or excreted outside the tissues even after three weeks of in vitro culture. Of the three tested genotypes, G14 had the greatest tendency to accumulate each of the examined metals, that is, it appeared to be the least tolerant genotype.
