Fruit growing
and viticulture of South Russia
Change of cation composition in process of the secondary fermentation of tirage mixture and after tirage extract in the presence of minerals of various deposits is studied. It is established that the dispersed minerals may significantly affect the content of individual cations of metals. Increase of their content as a result of processing of wine by betonite and other minerals may adversely affects on the wine quality.
The change of amino acid composition in the process of fermentation of tirage mixture was studied. A comparative assessment of influence of minerals from various deposits on the intensity of consumption of amino acids in the secondary fermentation is given. It is established that the amino acid composition of cuvee depends from many factors such as the accumulation of yeast biomass, a rate of sugar consumption, oxygen, nutrients of tirage mixture, used minerals and it affects the quality of sparkling wines.
The analysis of long-term tendencies in the development of industrial fruit growing is given and subject orientation of agro-economic research is defined. The role and evolution of methods of economic research and development in forming of pithy aspect of growing fruiting is shown.
Specific displays of abiotic stresses on fruit plants revealed as a result of monitoring in field and controllable conditions are described in this article. The reasons of display of some of them from point of view of physiological and biochemical processes occurring in a plant are designated. The examples of specific display of incompatibility of rootstocks and scions, and influence of rootstocks on intensity of scion development in the winter-spring period are presented. The ways of minimization of the damage from adverse weather conditions to fruit growing are offered.
The results of joint researches NCRRIH&V and Institute of Fruit Growing (Belarus) on ecological test of apple varieties of Belarus selection in the conditions of Krasnodar territory are presented in the article.
