Biological features of high altitude rare medicinal plant species Hedysarum theinum Krasnob. in Western Siberia cultivation

Abstract

The paper summarizes the results of a long-term introduction study of a rare alpine plant Hedysarum theinum Krasnob., which is widely used in medicine. We found that the species demonstrates sufficiently high seed productivity with adequate agrotechnical care under introduction conditions. Nevertheless, there were cases of a single lack of fruiting, which cannot be considered a reaction to different ecological conditions since these phenomena can also be observed in natural habitats; most likely, this is a feature of the reproductive biology of the species. The phenological characteristics, seed productivity, and seed germination of the species are given, and the range of variation in signs of the vegetative and generative spheres is established. The introduction assessment indicates high plasticity and a high degree of the species adaptation.
