Representatives of the Vitalbae prant L. sub-section of Clematis L. genus in the collection of the South-Ural botanical garden-institute of UFRC of the RAS

Results of the introduction researches of 5 species of Clematis in a collection of lianas of South-Ural Botanical Garden-Institute of Ufa Federal Research Centre are presented in article. According to phenological observations in 9 years (2007-2015) integrated assessment of introduction perspectives and introduced stability of clematises is given. The scale developed by P.I. Lapin and S.V. Sidneva for wood plants is used for assessment of introduction perspectives. Preliminary estimate of introduction stability is carried out according to a scale of N.V. Trulevich. Extent of ripening of shoots, winter hardiness, preservation of growth form, shoot-formation ability, generative development, ability to reproduction in culture were estimated. All species are characterized by stability of rhythmic processes and their fitness to local climatic conditions. Duration of the vegetative period consists of 5,5 months. Duration of flowering of C. ligusticifolia is more than 2,5 months, C. gouriana is more than 2 month, C. apiifolia, C. fargesii and C. brevicaudata is not less than 1,5 months. In accordance with the scale of introduction stability, all the studied species belong to the perspective group of II (80-85 points). All the species under investigation can be used in green landscaping in different regions of the South Urals.
