Abstract

For studying the living state of cenopopulation of polycentric biomorph it was offered to use the method of correlative analysis and asymmetry of vegetative signs of Poa angustifolia L. The received data demonstrated that the most informative indicators are the generalized correlation coefficient and unsymmetrical factor. The use of received criteria allows define the living state of vegetatively movable specie at only the single research

Highlights

  • The revelation of indicative signs and methods that allow define the vitality of vegetable population and make the prognosis of its development and so of the whole phytocenosis was always an important task of ecology

  • Internal connections in biological objects can define the degree of its correspondence to the concrete ecotope and the living state of organisms [2]

  • The use of such criterion allows define the living state of cenopopulation of polycentric biomorph already at the single receipt of the values given in the table 1

Summary

Introduction

The revelation of indicative signs and methods that allow define the vitality of vegetable population and make the prognosis of its development and so of the whole phytocenosis was always an important task of ecology. The study of internal connections between the separate organs is important for solving many theoretical and practical problems of ecology and phytocenology [1]. Internal connections in biological objects can define the degree of its correspondence to the concrete ecotope and the living state of organisms [2]. The prevalence of the high positive connections among the functionally important signs demonstrates the certain coordination in morphogenesis, in functioning and development of individuals, the fitness to ecotope conditions; its lack can indicate the disintegrative processes and be an early diagnostic signal of destructive phenomena [3]. 2.
