MODIFIED ASSESSMENT OF ORNAMENTAL PROPERTIES IN REPRESENTATIVES OF THE GENUS <i>DEUTZIA </i>THUNB. UNDER CONDITIONS OF THE CITY OF UFA
Based on the literature data and our own long-term observations, we have developed a modified assessment of decorative effects of Deutzia. The results of studying of decorative qualities of 12 species and 9 sorts of Deutzia Thunb. genus under the conditions of introduction in the South-Ural Botanical Garden-Institute - Subdivision of the Ufa Federal Research Centre of Scientific Centre of the Russian Academy of Sciences are presented in the article. A scale for assessing their decorativeness is proposed, according to the results of which 4 species and 4 sorts are classified as decorative, to the less decorative - 8 species and 5 sorts. D. amurensis, D. glabrata, D. parviflora gained the highest score among the species due to such factors as abundance of flowering, bush form, plant condition and high winter hardiness. Among sorts D. × magnifica, D. × hybrida 'Mont Rose', D. × hybrida 'Strawberry Fields', D. × hyb rida 'Pink Pompon', D. scabra 'Plena' gained the highest score. They are referred to the decorative group, as their scores were maximum in terms of: coloring of flower and inflorescence, size and shape of flower.
