Vitality and morphological changeability of Carex dioica L. individuals (Cyperaceae Juss.) on the territory of Western Polissya

Abstract

Vitality and morphological changeability of Carex dioica L. generative individuals in 4 habitats in the territory of Western Polissya were analysed. It is established that all the populations are characterised by high vitality and low interpopulation variety. A nega­tive correlation between the level of vitality of male and female individuals and their density is shown. The antropogenic influence and biotope heterogenety 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 depending on the environmental conditions.
