Wines are a rich source of polyphenols like anthocyanins, and these compounds has potential benefits for human health. The level of anthocyanins in the berry skins can be increased by water stress (S) and by exogenous applications of abscisic acid (ABA) during berry ripening. The objective was to determine the effects of exogenous ABA supply and S treatments on anthocyanin concentration in Vitis vinifera L. cv. Cabernet-Sauvignon. The study was carried out in Mendoza Province, Argentina. Two irrigation treatments: irrigated (W) and water stress (S), were applied:. Plants of W and S were separated into ABA treated (A) and control, without ABA (C). Finally, four treatments were performed: WC, WA, SC and SA. Exogenous ABA supply produced an enhancement on total antocyanins content in grapes without affecting parameters such as yield, foliar area, soluble solids and pH. The same increments were obtained in wines where S enhanced total anthocyanin concentration (10% vs WC). However, treatments did not affect different types of anthocyanin in the same way. S treatment mainly increased malvidin 3-O glucoside and ABA treatments enhanced all species in the same magnitude. Irrigated plants subjected to ABA treatments gave higher levels of total anthocyanin contents than stressed plants. SA.
