Phenolic profiles and antioxidant properties of young wines made from Yan73 (Vitis vinifera L.) and Cabernet Sauvignon (Vitis vinifera L.) grapes treated by 24-epibrassinolide.

The grape berries of two varieties, Yan73 (Vitis vinifera L.) and Cabernet Sauvignon (CS) (Vitis vinifera L.) were treated with 0.

Regulating the secondary metabolism in grape berry using exogenous 24-epibrassinolide for enhanced phenolics content and antioxidant capacity.

The objective of this study is to investigate the influence of application of exogenous 24-epibrassinolide (EBR) on the antioxidant capacity, anthocyanins and phenolics content of Vitis vinifera grape berry (cvs. Yan 73 and Cabernet Sauvignon). The grapevine clusters were sprayed with 0 (control), 0.

Exogenously applied abscisic acid to Yan73 (V. vinifera) grapes enhances phenolic content and antioxidant capacity of its wine.

Yan73 is a 'teinturier' red wine variety cultivated in China and widely used in winemaking to strengthen red wine colour. The objective of this study was to evaluate the effect of exogenous abscisic acid (ABA) applied to the grapevine cluster on the antioxidant capacity and phenolic content of the wine made from Yan73. Two hundred mg/l ABA was applied on Yan73 grapevine cluster during veraison.
