Abstract: In this paper,the 5-year oldgrapevines of Vitis vinifera L. Cabernet Sauvignon were subjected to reg-ular UV-C irradiation,and the effect of UV-C on the fruit quality formation and accumulation of polyphenols during berry development were studied. The results showed that the pattern of fruit quality formation and accumulation of polyphenols were not changed,but the fruit quality and content of polyphenols in mature berry were changed signifi-cantly by the regular UV-C irradiation. Under the moderate UV-C irradiation,no obvious changes in single berry weight,content of organic acid,and total phenol were observed,but the content of anthocyanins,total sugar were in-creased,and the accumulation of flavonoids and flavanols were induced significantly in mature berry,which sugges-ted that there was obvious improving in fruit quality. In addition,the effect of UV-C on the fruit quality formation and accumulation of polyphenols were development and dose-dependent.
