摘　　要：以晚熟葡萄品种红地球为试材,探讨了几种不同透光率的果袋对葡萄果实有关性状的影响,结果表明:不透光的复合袋极为显著地降低果实单粒重、总糖含量和糖酸比;透光率为16%的红色袋显著降低果实糖酸比,但对总糖含量、单粒重无显著影响;透光率为60%的无纺布袋对果实品质有一定提高作用;套袋处理的果实钙含量显著低于对照,且随着果袋透光率的降低而降低;透光率高的果袋袋内果实单宁含量偏高;各处理果实Vc含量均无显著差异。葡萄果实对光照强度的需求存在临界值,当袋内光照强度低于外界自然光照的1.4%左右时,果实生长发育开始受到影响。The effects of fruit bags with different transmittance on fruit relevant traits of Red Globe were studied in the experiment. The results showed that weight of single berry, total sugar and sugar-acid ratio decreased significantly as a result of using compound bags without transmittance as fruit bags. The red bags with 16% transmittance reduced the sugar-acid ratio significantly but had no significant effect on total sugar and weight of single berry. Non-wovens bags with 60% transmittance had a certain impact on the improving of fruit quality. Calcium contents of bagging treatments decreased with the decline of transmittance and lower than the control obviously. High transmittance contributed to the high content of tannin. There were no significant difference in Vc content among all treatments. There was a critical value for the requirement of light intensity. As the light intensity was under 1.4% of the natural lighting in the bags, fruit development would be affected.
