Biological peculiarities and characteristics of Erodium tataricum WILLD. cenopopulation in Khakasia

Biological and structural peculiarities of Erodium tataricum Willd. cenopopulations in natural surroundings of Khakasia are examined. It is found out that the species make two vegetal forms under the changing environmental conditions. Ontogeny is complete, regeneration does not take place. Two types of ontogeny are found out: morphological and dynamic (according to the rate of growth). Examined Erodium tataricum Willd. cenopopulations are normal and incomplete.
