套袋处理对南果梨果实外观品质的影响

Influence of bagging on the exterior fruit quality of Nanguoli pear

以48年生的南果梨树为试材,用单层、双层的果实袋进行不同时间套袋、去袋的处理,研究了果袋类型、不同套袋、去袋时间对南果梨果实外观品质的影响。试验结果表明:套袋可明显地改变果实的外观,5月底6月初套袋、提前半个月左右去袋可促进果实着色但使果个变小;套袋使果点颜色变浅、直径减小,果皮厚度降低。

A 48yeartree of Nanguoli pear variety was used for studying the influences of bagging on the exterior fruit quality. The results indicates that bagging treatment can change the exterior quality of the fruit obviously. The skin color can be better by timely putting up and putting down bags but bagging make the fruits smaller. Bagging treatment make the dot color faint, dot diameter decrease, skin thickness thin, while cuticular thicken, and fruits smaller. The earlier the fruit is bagged, the smaller the fruit is.
