There were presented the results of researches on cutting regeneration processes at 7 rootstock varieties of grapes at their rooting on water in this article. There were examined the key indicators of spear- and root-forming ability of cuttings
Differentiation has been conducted and valuation of the collection of lavender angustifolia and Lavandin according to the content of linalyl acetate, biometrics is shown, and correlations of economically valuable indicators in the cluster analysis are identified
The results of long-term population-genetic studies in wheat pathogen system “wheat – dangerous disease pathogens” associated with the study of the structure, variability, forecast of plant pathogen development and the host plant genetic diversity are introduced.
It is shown that it is necessary to develop polymorphic genetic disease resistance of plant populations to rehabilitate the agroecosystem phytosanitary state, which is possible only on the basis of broad genetic diversity of source material, taking into account the intraspecific differentiation of pathogens and tendencies of the changes
The results of immunological assessment of winter wheat varieties included in the State register of breeding achievements of the Russian Federation and the variety of different types of resistance to yellow leaf spot pathogen are presented in this article
According to the results of anatomical researches is determined, that under three sides spring punning of roots simultaneous annual applying of regalis number of grown closed (fruit) buds increase about 22–26 % during the first year, but then influence becomes weak and about the fifth year it needs the second (repeated) pruning of roots. Under two-sides pruning of roots a little decrease of size (caliber) is noticed in such sorts of apples as Gala and Golden Delicious
