| Summary: | The article contains a list of introduced specimens of the genus Sorbus L. - mountain ash in the Polar-Alpine Botanical Garden-Institute located above the Arctic Circle. The collection fund contains 56 samples of introduced plants of the genus Sorbus , belonging to 22 species and 1 subspecies. The article gives a comprehensive assessment of the viability and decorativeness of introduced plants of the genus Sorbus in the conditions of the Kola Subarctic. 75 % of the studied samples retain and are able to restore the growth shape. In half of the samples, the seeds ripen not annually, for reproduction in the culture it is necessary to attract seeds from other regions. Rowans with the highest vitality scores also have higher ornamental qualities. Evaluation of the viability and decorativeness of introduced plants of the genus Sorbus made it possible to divide the studied samples into groups: quite promising highly decorative, viable high and medium decorative, less and unpromising low and medium decorative, unviable medium and low decorative. In the conditions of the Kola Peninsula, the most viable and decorative S. aucuparia , S. aucuparia subsp. sibirica , S. sambucifolia , S. hybrida , S. commixta, S. tianschanica . The introduction of the species S. albovii , S. buschiana , S . fedorovii , S. subfusca , S. turkestanica is not promising, the plants are of interest for scientific collections. |
