Ecological and Phytocenological Attachment of Species of the Genus Allium L. in Montane Ecosystems of Eurasia

Pages: 565-570


Phytocenotic attachment of species of the genus Allium L. in Eurasia has been elucidated. It has been established that the highest species diversity is characteristic of xerophyte types of biomes and of rocky and stony vegetation. Amplitude humidity estimates of ecological scales for 56 species have been analyzed, and ecological areal of 15 species growing in Siberia has been described. It is demonstrated that in species playing an important role in the phytocenosis, the humidity tolerance amplitude is wider than that in species whose abundance in the community is not high.
