Production-ecological study of Carex pilosa Scop. species during its life cycle

Production-ecological characteristics (biomass dynamics, population density , size structure) and phenology of Carex pilosae S c o p. population in Car ici pilosae-Fagetum O b e r d. 1957 community were estimated in submountain -sedge beech forest stand during its life cycle. Aboveground biomass of juv enile individuals culminated in September (60.03 g.m(-2)), offshoots densit y ill May (240 shoots per m(2)). Juvenile individuals reached the height ma ximum in July (40.1 cm). The life cycle lasted 680 days, generative cycle d idn't represent more than 20% of the whole cycle during researched years fr om 1994-1996.
