Introduction studies of species of the genus Incarvillea Juss. in the Avrorin Polar-Alpine Botanical Garden-Institute

The species composition of the genus Incarvillea Juss., tested in PABGI since 1939, was analyzed. The seasonal rhythm of plant development was studied, the survival points and the introduction coefficient were calculated. It was found that most species only vegetate, had low survival points and an introduction coefficient < 1, and were not very suitable for introduction in the Kola Polar region. Only two species (Incarvillea zhogdianensis Gray- Wilson and Incarvillea mairei (H. Lev.) Grierson) had an introduction coefficient > 1. These species are promising for introduction; it is advisable to continue their study.
