Actinidia kolomikta (Maxim.) Maxim. - promising culture for the Southern Urals

The purpose of the study is to assess the prospects for the introduction and introduction resistance of actinidia kolomikta (Actinidia kolomikta (Maxim.) Maxim.) and its varieties Klara Zetkin and Septemberskaya of the lians collection of the South Ural Botanical GardenInstitute of the Ufa Federal Research Center of the Russian Academy of Sciences (Bashkir PreUrals, northern foreststeppe) for further expansion of the range of ornamental plants recommended for cultivation in the regions of the Southern Urals.The seasonal rhythm development observations were carried out over 13 years (2007-2020) in 7 phenological phases. Phenological observations were exercised in accordance with the generally accepted methodology. The degree of shoots ripening, winter hardiness, growth form preservation, shootforming ability, generative development, and the ability to reproduce in culture were subject to estimation. The scale developed byLapin and S.V. Sydneva for woody plants was used to assess the prospects of the introduction. The evaluation of the introduction resistance was implemented in accordance with N.V. Trulevich's scale. Winter hardiness was determined according to the scale developed by the GBS RAS. It was revealed that actinidia successfully passed the introduction tests. The studied taxa under cultural conditions are characterized by the stability of rhythmic processes and their adaptability to local climatic weather conditions. They are highly winterhardy and decorative throughout the growing season. The growing season lasts more than 5.5 months. An integral assessment of the data makes it possible to classify all the studied taxa in the first group of promising introduction, A. kolomikta and its varieties are highly resistant plants. The culture is promising for vertical planting of gardens and parks in the city of Ufa and other settlements in the South Urals.
