Fruit growing
and viticulture of South Russia

Annotation

Ukraine is one of the few countries that are on par with the most famous wine regions of France, so here it is possible to produce high-quality brands of wines valuable over the world. One of the reserves to increase in the yield and quality of viticulture products is the use of growth regulators. The purpose of this research was to study the influence of Biolan and Vympel growth regulators on the quality of grapes and wine materials of classic white Aligote and Rkatsiteli varieties. Experiments in Aligote plantings showed a significant influence the studied preparations on the yield and quality of grapes and wine. The increase in the mass of the bunch under the influence of the preparations led to a higher yield in the experimental variants, and the quality indicators also improved. The highest yield from the bush was obtained with the Biolan preparation (0.52 kg more control), the yield in this variant increased by 22%. The Vympel increased in the yield from the bush by 0.44 kg, and the yield by 18.7%. The Biolan increased the yield of Rkatsiteli by 26.3%, the Vympel increased this index by 25.5%. The acidity index of berries juice in both varieties of grapes when processing plants with Biolan and Vympel preparations was lower by 0.7-1.4 g / dm3 below the control. The economic analysis have showed the expediency of using of preparations Biolan and Vympel in the cultivation of white grapes varieties of Aligote and Rkatsiteli. The level of profitability in the case of using the Vympel preparation was higher.
