Název v původním jazyce

POST-HARVEST BIOMASS STOCK AND PRODUCTIVITY OF CALAMAGROSTIS EPIGEJOS COMMUNITY UNDER BEECH AND SPRUCE FOREST STAND

Popis výsledku v původním jazyce

We investigated the above- and below-ground standing biomass and production of plant communities dominated by bushgrass (Calamagrostis epigejos) colonizing forest clearings created by harvesting beechspruce forest stands. Above-ground living biomass of these communities was 6.6 t.ha-1, while above-ground litter made up 5.6 t.ha-1. Below-ground standing biomass was 6.6 t.ha-1 and production was 1.6 t.ha-1. Inter-annual fluctuations in production were rather high and did not clearly follow weather alternations. We hypothesize about some of the reasons for this. A negative correlation between litter and production of bushgrass rhizomes and root were found. The amount of bushgrass above-ground biomass did not affect species? richness, but a higher amount of its roots inhibited occurrence of other species, especially other dominants in the forest clearings Epilobium angustifolium and Rubus idaeus. The bushgrass produced rhizomes mainly at micro-sites with higher proportions to other species
