Description

This article investigates the effects of growth regulators on the chemical composition of grape (Vitis vinifera L.) varieties. According to the experimental results, these substances were found to increase the weight of grape clusters while slightly reducing the sugar content of the juice and increasing its acidity. The highest result was observed with the combination of gibberellin + Dropp (100 mg/L + 25 mg/L). The study provides scientifically based recommendations for improving the yield and chemical composition of grape varieties under the conditions of Uzbekistan.
