THE INFLUENCE OF STOCKING, SHADE DEGREE, PRECIPITATION DEPTH AND AVERAGE SOIL-TEMPERATURE ON THE ABOVEGROUND AND BELOW-GROUND BIOMASS PRODUCTION OF SELECTED PLANT-SPECIES

The work presents results of a three years productional research on th e aboveground and belowground biomass of selected plant species. The i nfluence of stocking, shade degree, total precipitation depth and aver age soil temperature in a 5 cm depth on the biomass production was eva luated as well. The research was undertaken in the submountane beech f orest stands at the Ecological-Experimental Station (EES) in the Kremn icke vrchy Mts. The highest production values were recorded on the plo t H, the lowest ones on the plot. K. The biomass production was signif icantly influenced by ''light factors'', the lowest influence was obse rved at the average soil temperature.
