Allelopathy as a mechanism of interaction plants and plants, plants and insects, plants and microorganisms

Abstract

The review article discusses the current understanding of the role of allelopathy in the interaction between plant species, insects and microorganisms within plant communities. The characteristic of the biocenosis and its leading structural component of phytocenosis, which determines the species composition of the zoocenosis, mycocenosis and microbiocenosis, is given. Each individual biocenosis, excreting various metabolic products into the external environment, creates around itself a specific environment that can be toxic, favorable, or indifferent for a number of growing plants, herbivorous insects, microorganisms. According to N.Vavilov, V.Sukachev, T.Rabotnov, a classic concept, along with competition for sharing energy and food resources of the habitat, a mechanism of interaction is used, implemented by changing chemical and physical environmental factors. The article discusses modern approaches to identifying the role of allelopathy in interactions between representatives of biota in biogeocenes, which is very relevant for work on chemical immunization of plants.
