Borschevskyi M. Rhus typhina L. in conditions of Kyiv city (state of life, successful of introduction, response to stress factors)

The thesis is devoted to the study of biological, ecological features and decorative properties of species and cultivars Rh. typhina in terms of Kiev for widespread use in landscaping. Identify and analyze the species composition of the genus Rhus, which is represented in the collections of urban gardening and botanical institutions in the country. The seasonal rhythm of growth and development of Rh. typhina and their consistency with the climatic conditions in Kiev. During the phenological observations regularities in the rhythms of development, as well as the dependence phenological phase of the meteorological indicators. Identified potential frost Rh. typhina by the method of direct freezing. Assess the level of resistance of plants to drought species, measuring the electrical conductivity of the leaves. Determined by the functional state of chlorophyll fluorescence induction. Optimal composition of culture media for the cultivation of the genus Rhus investigated in in vitro culture and rooted planting material obtained by direct morphogenesis.
