Structure of the cenopopulation of Perovskia kudrjaschevii Gorschk. under the conditions of the southern Pamir-Alay (Tajikistan)

This article presents the results of a study on the ontogenetic structure of cenopopulations of Perovskia kudrjaschevii Gorschk. under the conditions of the southern Pamir-Alay. It was found that the self-maintenance of the cenopopulations occurs mainly through vegetative means due to the development of xylorhizomes and their fragmentation, which leads to effective rejuvenation of ramets to the virginal state. A comparison of the ontogenetic structure of cenopopulations in different habitats revealed two types of spectra: a centered spectrum with a peak in middle-aged generative individuals, and a right-skewed spectrum with a peak in old generative individuals. The latter spectrum type forms under high anthropogenic pressure. All cenopopulations, based on demographic indicators, are characterized as mature and stable.
