FINE ROOT STANDING STOCK AND PRODUCTION IN YOUNG BEECH AND SPRUCE STANDS

Popis výsledku v původním jazyce

Fine roots (defined by a maximum diameter of 2 mm) and assimilatory organs are the compartments which rotate carbon much faster than any other tree part. We focused on quantification of fine roots in young European beech and Norway spruce trees growing under the same ecological conditions. Standing stock of fine roots was estimated by soil coring during 2009 ? 2012. Fine root production was established by the in-growth bag method. Standing stock and productions of fine roots were comparable in both treespecies. The quantity of fine root biomass (at a soil depth of 0 ?50 cm) varied inter-annually between 6.08 and 7.41 t per ha in the beech and from 5.10 to 6.49 t per ha in the spruce stand. Annual production of fine roots (soil depth of 0 ? 30 cm) wasbetween 1.11 and 1.63 t ha-1 in beech and between 0.95 and 1.54 t.ha-1 in spruce. We found that fine root standing stock at the beginning of each growing season was related to climatic conditions in the previous year. Annual fine root
