Abstract

In the work the results of studying 10 populations of Hedysarum setigerum Turcz. ex Fisch. et C.A. Mey. in the South of Siberia (Mountain Altai, Tuva, Baikal coast). Ontogenesis of this species in nature and in introduction experiment was studied, during which of the main root caudex life form was formed. Identifi ed three types of ontogenetic spectra of populations: centered in a low-disturbed coenosis, left-hand spectrum under moderate pasture load, right-hand spectrum under strong pasture load and recreation presure.
