Fruit growing
and viticulture of South Russia
Construction of plantings, forming of crown
It has been established that in the conditions of the foothills in the region of the Western Approaches of Caucasus in the plantations with the rows oriented to the westwards from the east the application of new methods of lighting of the rounded tree krones improves light conditions and apple fruit quality.
Quality Management
The relationship between biochemical characteristics and physiological mechanisms of apple resistance to abiotic stress of different origin varieties are established. The dynamics of the metabolism of apple varieties in view phenological phases of development, and during their long storage is analyzed. Quality indicators of high resistance of fruits to physiological diseases during stor-age, allowing to predict the storage period are established
The results of the technological evaluation of apple varieties with immune or high resistant to scab for juice production of selection ARRIHB are presented and varieties and hybrids, allowing to obtain a product with higher rates of food security are selected
Regularities of wine quality formation, their physical and chemical and biological parameters depending from the agronomic factors are revealed as a result of years research. The mathematical models that can control the process of creation of wine quality are worked out
Methods of defoliation and crop regulation in the vineyards of Merlot variety, growing in the Temryuk region are studied. Clones of grapes with a positive reaction to the agricultural practices are selected. Recom-mendations for production taking into account the results of study are given
Problems and contradictions of harmonization of technical regulations on the domestic wine products to the rules of the European Union and the International Organization of Grapes and Wine are considered
The criteria of use fragrances in the food production are considered. The simplest and most effective method to detect synthetic fragrances is selected and justified, a method of identification of 1,2-propylene glycol by gas-liquid chromatography is developed. The results of testing of method, confirming the efficiency of the method approve are presented
The results of study on the development and practical application of identification methods of volatile aroma components of cognac production and an assessment of cognac and brandy, produced from own raw materials on the Russian territory are presented. Based on the analysis of data the nomenclature of indicative criteria of quality with a typical experimentally established range of volatile components concentrations is selected
The results of comparative evaluation of the cognac quality (including the composition of their non-volatile impurities), produced by enterprises of Krasnodar, Stavropol region and the Republic of Armenia are presented
A comparative study of extractive non-volatile components of the cognac spirits produed by Naurskyi and Kizliarskiy wineries was conducted
Phytosanitary condition of plants
Data on changes in the qualitative and quantitative content of metal cations in the dry red wines under the influence of fungal and bacterial microbiofungicides applied in the systems of protection from mildew are presented. The positive influence of biologized protect on the quality of dry red wines is noted
Storage of fruits and berries production and grapes
The comparative assessment of the fruit quality of 9 immune to scab apple varieties at the beginning and end of storage in two modes (+2 C and -1 C) is presented. Biochemical composition of fruits was studied. The degree of affection with various fruits microbiological and physiological diseases during storage is shown. Genotypic (varietal) stability of new varieties of apple fruit to disease is revealed. It was established that different genotypic groups require selection of storage temperature
The influence of the cork seal on the wine quality in the process of storage was evaluated. The characteristics of the cork stoppers of various kinds are researched, microbiological evaluation ones was realized
Processing of fruit and berries production and grapes
The results of study of biochemical changes of walnut of various degree of maturity are presented. New types of functional products with walnut being breast maturity are developed
The comparative evaluation of technical parameters and chemical composition of 12 persimmon varieties is presented. Perspective varieties with maximum accumulation of biologically active substances, which should be recommended for fresh consumption and canning functional purpose are selected. New types of canning products are developed
Established that using a pneumatic press batch can increase the yield of the wort to 65 dal from 1 ton of grapes without of compromising for the quality of champagnes and sparkling wines
The chemical composition of the juice obtained from watermelon early and medium maturing, grown in the southern Russia is studied. Regularities between physical and chemical composition of the juice used yeast races and quality of the wine stock are established. Our study has allowed to offer the technology of production of high-quality hard liquor from watermelon
