The characteristic of symbiotic relationships is presented on the example of vesicular-arbuscular mycorrhiza in the case of Trifolium pratenseL. at different succession stages of meadow phytocenoses. It is shown that the functional potential of symbiosis changes in the course of succession and is fully revealed under conditions of an undisturbed climax community. The fundamental possibility of biological diagnostics of the state of phytocenosis using discriminant analysis according to the indices of an individual legume plant, taking into account the symbiotic potential, has been demonstrated.
