Integrated assessment of introduction prospects of Deutzia Thunb. genus representatives in the South-Ural Botanical Garden-Institute (Ufa)

The paper contains results of introduced study of species, hybrids and sorts of Deutzia Thunb. genus in the South-Ural botanical garden-institute (Ufa). The collection of Deutzia is one of the largest among ornamental shrubs in the botanical garden. The objects of researches were 12 species, 10 hybrids and sorts of Deutzia . Introduced researches of all taxons were conducted within 10 years (2007-2017). Throughout the entire period of observations the following indicators were annually estimated: lignification of escapes, winter hardiness, preservation of a form of growth, sprout-formation ability, a gain in height, generative development, possible ways of reproduction in the culture. The analysis of the obtained data shows that specific taxons are belong to three groups: quite perspective, perspective and less perspective. The greatest possible indicators characterize 3 species - D. amurensis , D. glabrata, D. parviflora . All of them can be recommended for broad application in gardening of settlements of the Bashkortostan Republic. Perspective and less perspective groups contained 4 species each. Hybrids and sorts in the collection belong to three groups: perspective (II), less perspective (III) completely unusable (VI); in the latter group contains one hybrid.
