果袋颜色对设施葡萄果实品质的影响

Effect of Fruit Bag Color on Grape Quality in Facility Condition

以"红地球"葡萄为试材,采用不同颜色果袋进行套袋处理,以不套袋为对照,研究了不同颜色果袋内温度、光照的变化及其对设施葡萄果实品质的影响。结果表明:不同颜色果袋均显著提高了相应光质光谱的比例,并且均降低了光辐射、光照强度;红色果袋提高了袋内温度。蓝袋、绿袋、白袋果实的总糖含量与对照差异不显著;在总酚、原花青素的含量上,各套袋处理均显著低于对照。由此可见,套袋会影响葡萄着色;黄袋、红袋对葡萄果实品质的负效应更大。

Taking ‘Red globe’ grape as teat material,by different color of fruit bags for bagging treatments,with the treatment without fruit bagging as the control （CK）, the effect of different color of fruit bag on the changes of temperature, light and fruit quality of grape in solar greenhouse were studied. The results showed that different colors of fruit bags were significantly increased the proportion of light spectrum, and reduced the light radiation, the intensity of illumination. Red fruit bag raised the temperature inside the bag. The total sugar content of blue bags, green bags and white bags had no significant difference with the control. Bagging treatments were significantly lower than the control on the content of total phenolic and proanthocyanidins. Thus, bagging affected grape color. Yellow bags and red bags had more negative effect on fruit quality of grape.
