The influence of rootstock on vegetative growth, yield and quality of grapes of Vitis Vinifera L. Cabernet Sauvignon
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 101, Issue
Abstract
The influence of rootstock variety on vigor and yield, as well as quality of Cabernet Sauvignon grapes, cultivated under the environmental conditions of AC «Shabo» (Odessa region, Ukraine) was investigated. The highest vigor of vines was typical for the combination of cl. 685х110 R, the lowest – for cl. 15х3309 С. Low yields of these combinations caused the largest exposed leaf area per kg of grapes. According to monomeric flavonoid composition, scion-rootstock combination of cl. 685x110 R was characterized by the highest content of flavonols and anthocyanins and the lowest content of flavan-3-ols. Specific properties of the phenolic complex – technological reserve, concentration in fresh must and after the maceration of crushed berries, macerating ability of must – had the highest values for the sample of grapes of cl. 685x110 R. A similar trend was observed with regard to the technological reserve of anthocyanins and their concentration in must after the maceration of crushed berries
