摘要

The results of our study of the invasive species Hordeum jubatum L. in various ecological-geographical conditions of the Southern Urals are presented. The 32 coenopopulations (CPs) of the species in the Bashkir Cis-Ural and Trans-Ural regions in Orenburg and Chelyabinsk oblasts were investigated. The populations studied were revealed to belong to several types of vegetation communities, namely, the Polygono avicularis-Hordeetum jubati association (Abramova and Golovanov, 2016), the derivate community Hordeum jubatum [Scorzonero-Juncetea gerardii], the derivate community Hordeum jubatum [Cynosurion], and the derivate community Hordeum jubatum [Artemisietea vulgaris/Stellarietea mediae]. Our study of key morphometric parameters has shown that the undisturbed CP Zamorskoye-1 (Orenburg oblast) was in the lead, where the growth conditions were favorable for the species. The most variable morphometric parameters among the populations are as follows: the number of generative shoots, the leaf length, and the quantity of seeds. In the 17 prospering CPs, the prevalence of individuals of the highest class was noted; they were located in the undisturbed or weakly disturbed habitats. One CP was attributed to equilibrium ones, and the others were depressive. By the results of our cluster analysis, three CPs located in different geographic zones and having the maximum or minimum values in the majority of their morphometric parameters are most different from the total data set. Further monitoring of the centers of invasion and distribution of Hordeum jubatum species across the territory of the Southern Urals is necessary.
