Abstract
Ontomorphogenesis of the short-rhizomed life form of the species is described. Five coenopopulations of Phlomoides tuberosa (L.) Moench were studied in the south of Siberia (Mountain Altai, Khakassia. Tuva). Th ree types of ontogenetic spectrums of coenopopulations were identified: left-sided in conditions of enhanced anthropogenic impact, bimodal under moderate pasture load and centered in a low-disturbed cenosis. Th e optimum state of P. tuberosa coenopopulations is reached in open, fairly moistened meadow and meadow-steppe communities experiencing moderate anthropogenic impact. Under these conditions, developed generative individuals of P. tuberosa are formed and its regular seed renewal is ensured.
