Pankiv N. Structure of populations of mountain crownvetch (Coronilla coronata L., Fabaceae) on the north-east limit of the area and its indication value.

The objects are populations of Coronilla coronata. The aim is to study the features of populations structure and morphological variabilitation C. coronata on north-eastern border of the area. The methods are generally accepted methods of population researches. As a result of implementation of work conformities to the regularity of morphological differentiation and populations structure of relict species are studied in isolated locality on verge of natural habitat, populations mechanisms, which are predetermine firmness and stability of species in the critical terms of existence are found out. The features of modern structure of local populations of species are studied in different ecologo-coenotical terms, that enabled to define him the sozological state, and also sozological positions of all connected with him to the florocoenotical complex. As a result of researches, possibility of the use of structural parameters of populations of species for the indication of the state of floroecotopological complexes of pratosteppephiton in region of north-western Podillia is conditioned. Application spheres are the preservation of a floroecotopological complexes of pratosteppephiton, phitomonitoring.
