SOME ECOLOGICAL PECULIARITIES OF BULBOCODIUM VERSICOLOR (KER-GAWL.) SPRENG. (COLCHICACEAE, MAGNOLIOPHYTA) IN THE LOWER VOLGA REGION

The paper presents the results of our four-year observation of Bulbocodium versicolor (Ker-Gawl.) Spreng populations in the Saratov and Volgograd regions. A low ecological plasticity of the species was established. Although the species grows in steppe phytocenoses that vary in composition and structure, the specimens’ morphology was rather conservative, which can be explained by the homogeneity of the species’ vegetation conditions over the territory under study during active vegetation and flowering. It is shown that in the Lower Volga region, B.
