摘　　要：以‘户太八号’葡萄为试材,测定露地栽培与避雨栽培2种模式下,葡萄果实大小、硬度、果梗拉力、糖酸等基本指标及避雨栽培对浆果酚类物质、香气物质及抗氧化活性的影响。结果表明:避雨栽培下,果粒粒径及果穗均小于露地栽培,去皮果实硬度比露地栽培高13.56%,带皮果粒硬度与果梗拉力分别比露地栽培低7.04%和9.73%;避雨栽培可提高糖质量浓度,但差异不显著,固酸比显著提高;pH及总酸在果实发育时期极显著低于露地栽培葡萄;与露地栽培相比,避雨栽培葡萄果实总酚、单宁及总花色苷质量分数均呈现显著降低趋势,而香气物质总相对含量则比露地栽培提高4.95%;另外,避雨栽培会降低葡萄的抗氧化活性,葡萄果皮清除自由基的能力显著降低,但葡萄果肉清除自由基的能力变化不大。The objective of this study is to compare the fruit size, hardness, sugar and acids content and other indicators of dominate table grape cultivar ＇Hutai No. 8＇ under rain-shelter cultivation and open-field cultivation. Meanwhile, the influence of rain-shelter cultivation on aroma substance, poly- phenols and antioxidant activity of grape berries were also investigated, so as to guide the production of ＇Hutai No. 8~ grape. The results showed that： compared with the open-field cultivation, rain-shel- ter cultivation had smaller size of grape berries and cluster , with higher hardness of peeled grape ber- ries by 13.56%, lower fruit hardness without peel by 7. 040/4, and lower tension of stems by 9.73~//oo . The rain-shelter cultivation can increase the sugar mass concentration of grape berries with no significant difference observed, however, the ratio of soluble solid mass concentration to titration acid im- proved significantly. The value of pH, mass concentration of acid, total phenolic, tannins and antho- cyanins of grapes under rain-shelter cultivation were all lower significantly than those of open-field cultivation. The total relative content of aroma was higher by 4.95% compared with the open-field cultivation. Meanwhile, the antioxidant activity of grape berries under open-field cultivation was lower than the open-field cultivation. The free radical scavenging ability of grape skins under rain-shelter cultivation decreased significantly while no obvious change was observed in grape pulp.
