The paper presents research results on the main parameters of cenopopulation structure of a Black Sea Coast endemic species under different ecological and phytocenotic growing conditions and at various stages of pasture digression. The differences in ontogenetic structure are related to phytocenotic characteristics of habitats and unequal seed regeneration. The optimum conditions for growth potential realization of individuals are determined.

Keywords: cenopopulation, vitality, variability
