Morphological variability of Carex dioica L. (Cyperaceae Juss.) in Polissya region

Morphological variability of Carex dioica L. generative individuals in 4 habitats on the territory of Polissya has analysed. It is established that antropogenic influence and biotope heterogenity determine the highest level of morphological changeability of individuals in one of the localities on the bog Koza. The length of leaves and stems are the most variable traits which depend on the environmental conditions. Stability of such characteristics, as a width of leaves and a length of spikes are determined by their important diagnostic value and application in the systematic of sedges.
