| 中文摘要: |
| 葡萄套袋能提升果面光洁度，也是调控葡萄转色成熟的有效手段。本研究以‘宝光’葡萄果实为试验材料，分别进行套白袋、蓝袋和绿袋处理，比较了果实转色期和成熟期的品质变化。研究结果显示，不同颜色果袋的透光率存在显著差异，光照强度和光合有效辐射的强弱顺序均为白袋>蓝袋>绿袋；其中，蓝袋相对于绿袋在400~500 nm处透过率有显著差异。在三种套袋处理中，相对于绿袋，白袋和蓝袋更有利葡萄果实的可溶性固形物的积累。‘宝光’葡萄果皮色素的主要类型是锦葵花色素和矢车菊色素，而白袋和蓝袋处理在提升浆果果面亮度和促进主要的花青素积累方面优于绿袋。白袋和蓝袋处理促进了花青素合成基因（VvCHS、VvF3H、VvDFR、VvANS、VvLAR）的表达，而绿袋处理则起到了抑制作用。本研究为葡萄熟期调控栽培过程中，基于套袋调控果实成熟的技术提供了参考。 |
| 英文摘要: |
| Grape bagging enhances the smoothness of the fruit surface and serves as an effective method to regulate the color and maturity of grapes. In this study, ‘Baoguang’ grape fruits were used as test materials and treated with white, blue, and green bags to compare quality changes during the veraison and harvest periods. The results indicate significant differences in light transmission among the colored bags. The order of light intensity and photosynthetically active radiation (PAR) was white bag > blue bag > green bag. Notably, the blue bag exhibited a 400~500 nm wavelength range with significantly higher transmittance compared to the green bag. Among the three bagging treatments, white and blue bags were more conducive to the accumulation of soluble solids in grape fruits than green bags. The primary pigments in the skin of ‘Baoguang’ grapes were malvidin and cyanidin, with white and blue bags outperforming green bags in enhancing berry surface brightness and promoting anthocyanin accumulation. Furthermore, white and blue bag treatments upregulated the expression of anthocyanin synthesis genes (VvCHS, VvF3H, VvDFR, VvANS, VvLAR), while the green bag treatment had an inhibitory effect. This study provides valuable insights into the application of bagging technology for controlling grape ripening and quality during cultivation. |
