Effects of Bagging on Fruit Quality and Variation of Skin Pigment of Peach

In this paper,'August peach' and 'Beijing 24 peach' fruit bagging experiments were conducted with the single-layer paper bag,double-layer paper bag and news paper bag.The results showed that(ⅰ)After bagging the growth of vertical and horizontal diameter of fruits were slowed,and the fruit weight decreased slightly,there were most significant with the double-layer paper bag;(ⅱ)After bagging the contents of fruit soluble solids,total soluble sugar and vitamin C were lower than that without bagging fruit,and the total acid was slightly higher than that without bagging fruit,there were still most significant with the double-layer paper bag;(ⅲ)The contents of chlorophyll A,chlorophyll B and carotenoids of bagging fruit decreased in fruit maturity,but the anthocyanin content increased and the color of fruit was more vivid compared with the test control,the effects of double-layer paper bag and single-layer paper were obvious.
