Effects of Different Bagging Treatments on Fruit Quality of Jinlan Pomelo

不同套袋处理对金兰柚果实品质的影响

In order to improve the exterior and interior quality of Jinlan pomelo,the suitable paper bag for Jinlan pomelo were screened through different bagging treatments involving single layer yellow paper bag,double layer yellow paper bag,three layer yellow paper bag,single layer red paper bag,double layer red paper bag,three layer red paper bag and no bagging.The results showed that bagging could increase fruit weight and fruit brightness,promote the coloring of fruit and improve fruit appearance quality.The titratable acid content of fruit decreased and the sugaracid ratio and soluble solid-acid ratio of fruit increased after the treatment of yellow paper bags.Double layer yellow paper bag could significantly increase the VC content,which had better effect on improving the exterior quality and interior quality than other treatments.This study provided reference for selecting the paper bag type for Jinlan pomelo.

为改善金兰柚外观品质和内在品质,通过不同果实套袋处理(单层黄色纸袋、双层黄色纸袋、三层黄色纸袋、单层红色纸袋、双层红色纸袋、三层红色纸袋及不套袋)试验,筛选出适宜金兰柚的纸袋类型。结果表明套袋有助于增加果实重量、提高果面亮度、促进果实转色,改善果实外观品质。黄色纸袋套袋后可以降低果实可滴定酸含量,增加果实糖酸比和固酸比;双层黄色纸袋能显著提高果实VC含量,在综合提高外观品质和内在品质上较其他处理效果好。本研究为金兰柚纸袋类型选择提供了参考。
