Coenopopulations of Paeonia tenuifolia L. (Paeoniaceae) in the steppe culturphytocoenoses

The results of the study of the coenopopulations of Paeonia tenuifolia L. in the artificial steppes plots “Steppes of Ukraine” and “Caucasus” in M.M. Grishko National Botanical Gardens of National Academy of Sciences of Ukraine are presented. The description of vegetation cover, the main parameters of the introductive populations of Paeonia tenuifolia and successfulness of its introductions are characterized. The possibility of cultivation of Paeonia tenuifolia without supplementary methods of its support are showed. Modeling of the populations of Paeonia tenuifolia in artificial ecosystems as a method of its ex situ protection are considered.
