摘 要:以设施栽培夏黑葡萄为材料,在转色初期进行干旱胁迫处理,以正常灌溉为对照,研究了干旱胁迫在该时期对葡萄果皮着色的影响。结果表明:在葡萄转色初期干旱胁迫可导致果皮中MDA含量升高及抗氧化酶类活性升高,有利于葡萄还原糖积累及可滴定酸降低,尤其在50着色阶段,此外该时期的干旱胁迫促进了果皮中总酚、类黄酮及花青素积累。研究认为,葡萄转色初期干旱胁迫可以调节果实的生长发育,促进果实着色。In this paper,the effects of drought stress on grape skin coloration during initial veraison were studied by using facility cultivation of summer black grape as the material and normal irrigation as the control.The results showed that drought stress during initial veraison could lead to the increase of MDA content and the increase of antioxidant enzyme activity in grape skins,which was beneficial to the accumulation of reducing sugar and titrable acid,especially in the 50%coloration stage.In addition,drought stress in this period promoted the accumulation of total phenols,flavonoids and anthocyanins in grape skins.It is believed that drought stress during initial veraison can regulate the growth and development of fruit and promote fruit coloration.
