Water deficit modifies the concentration of the aroma compounds of grape berries, but little information is available on the effect of deficits applied at different phenological stages. We evaluated the effect of deficit irrigation on glycosylated volatile organic compounds (VOCs) responsible for the aroma of berries of Sangiovese and Merlot cultivars grafted on 1103P or SO4 rootstocks.

灌溉不足对嫁接在两种砧木上的 Vitis vinifera L.（cvs Sangiovese 和 Merlot）浆果的香气成分有不同的影响

水分亏缺会改变葡萄浆果香气化合物的浓度，但关于在不同物候阶段应用亏缺的影响的信息很少。我们评估了缺水灌溉对糖基化挥发性有机化合物 (VOC) 的影响，这些化合物是嫁接在 1103P 或 SO4 砧木上的桑娇维塞和梅洛品种的浆果香气。
