摘要
以白肉枇杷贵妃为试材,分析了3种套袋材料(单层牛皮纸、单层牛皮纸+网兜、内黑外黄双层纸袋)对果实外观及内在品质的影响。结果表明:套袋能显著降低果实锈斑病的病情指数和炭疽病的发病率,其中以单层牛皮纸+网兜效果最佳;套袋使果面光洁、色泽均匀;套袋对果实单果重影响不显著;套袋后果实总糖、可滴定酸含量降低;单层牛皮纸+网兜处理有利于提高果肉游离氨基酸含量;内黑外黄双层纸袋的果肉类胡萝卜素含量极显著高于其他套袋处理;套袋有利于果肉类黄酮含量的积累。
Effect of bagging on fruit appearance and quality was studied on the white flesh Guifei loquat（Eriobotrya japonica Lindl.）.Three types of bags（i.e.,the single-layer kraft paper bag,the single-layer kraft paper bag ＋ meshed bag,and the double-layer,dark interior,yellow paper bag）.The results showed that the rust spot disease index and incidence of anthracnose significantly decreased when the fruits were covered with the bags,particularly when the kraft paper bag over wrapped with a meshed bag（KPMB） was used.The bagging also promoted luster of the loquat fruits.On the other hand,the fruit weight was not significantly affected,and the total sugar and titratable acid contents were lowered.Compared with Control,bagging with KPMB increased the fruit＇s amino acid content.The fruits bagged with the double-layer,dark interior yellow paper bags had higher carotenoid content in its flesh than Control.Bagging seemed to be conducive to the flavonoid accumulation in the flesh.Over all,KPMB appeared to be the most appropriate material for the bagging of Guifei loquat.
