Abstract

Ontomorphogenesis and the ontogenetic structure of cenopopulations of Scutellaria comosa have been studied under natural conditions. A brief ecological and phytocenotic characteristic of its habitats is given. The life form of the species is a vegetatively immobile aeroxyl sympodially growing shrub. Morphogenesis phases are described. The shoot structure of an adult is represented by a system of branched composite skeletal axes (an architectural unit) formed by four types of partially dying perennial shoots. Ontogenesis of S. comosa is simple, incomplete, senile individuals are absent. Left-sided, centered, and right-sided ontogenetic spectra of coenopopulations were revealed. Their diversity in different ecological and coenotic conditions is determined by the change in the rate of development of individuals and the frequency of seed renewal.
