XVI International Botanical Congess

The purpose of this study is to investigate the morphophisiological characteristics of the introducted forms of Ch.xsuperba (Fraxm) Rehd in the northeastern part of Russia (Middle Urals). It presents the biochemical evolution of the yield. It defines the possibilities of seed reproduction of the introducted species, what is important for selecting and growing of the planting material in landscaping, phitodesign and greenery. It can also be useful in selection and hybridization of chemosorts accumulating biologically active substances (organic acids, pectic material, vitamins C, P) in big amounts. We give the analysis of electrophoretical changes of alloenzymes in the leaves. As a result of the study there were planted motherplants of the most promising samples.
