Abstract

The study of natural populations of medicinal plants has an important applied and theoretical significance. The aim of this study was to investigate the taxonomic composition, composition of life forms and ecological groups of populations with the participation of medicinal species Scabiosa ochroleuca L., to compile ontogenetic spectra of the plant. In Central Kazakhstan (within Karaganda and Ulytau regions) S. ochroleuca has a wide area of growth, including the territories of Karkaraly, Buiratau, Kent, Ortau, Kyzyltau, Ku, Bektauat, Spasskiye hills, valleys of Sarysu, Nura, Sherubai-Nura rivers, Korneevsky forests, etc. The results of analysis of 8 populations showed that their species composition includes 142 species from 98 genera and 31 families. The dominant families are Asteraceae, Poaceae, Rosaceae and Fabaceae. Among the life forms of the species composition of the populations, herbaceous minor perennials, perennials, semi-shrubs, shrubs and trees are described. The predominant number of species was assigned to herbaceous perennials (109 taxa). Among ecological groups, mesophytes, mesoxerophytes, xeromesophytes, xerophytes, mesohygrophytes and hygrophytes were identified. Mesophytes and xerophytes were identified as the predominant groups. All studied populations are characterized by a single type of ontogenetic spectrum - left-handed with predominance of juvenile individuals.
