Сохранение раритетных видов флоры юго-востока Украины в Донецком ботаническом саду НАН Украины

Abstract

The results of the introduction of rarity species from the south-eastern Ukraine natural flora are presented. Based on the complex of criteria and methodical approaches to forming of the collections, the rate of introduction success is analysed. Representativity of the collection species of the natural flora in relation to south-eastern Ukrainian flora is 37%, and that of the steppe phyton is 82%. The structure of the collection–exposition complex of “Ukrainian Steppes” including monoculture and artificial phytocenoses within which above 200 rarity species are protected is characterized.
