摘要: 研究了红富士苹果套袋后果皮色素含量和果实糖、酸含量的变化。结果表明,果实套袋后果皮叶绿素含量一直低于对照果实,其中chla的含量降低最多,并且与总叶绿素的含量变化动态相似,类胡萝卜素的含量降低不大,这可能有利于果实着色;成熟期果实果皮花青苷含量迅速上升,摘袋5d后其含量超过对照,采收时超过对照1倍以上,使果实着色更鲜艳;套袋果实的可滴定酸含量显著降低,总糖、还原糖及各种可溶性糖和淀粉的含量均不同程度的降低,但是套袋果实各种糖、酸等含量变化趋势与对照相同。

Abstract: The experiment was carried on in Red Fuji apple with paper bags during fruit development. The result was showed as follows: The chlorophyll content in fruit skin of bagging apple was lower than control. Among them, Chl.a was decreased most and it was parallel with total chlorophyll content. The capacity of carotenoid was decreased little, which may be more advantageous to the fruit coloring. The content of anthocyanin was notably lower than control during fruit maturation. After 5 days of bag removal, its content surpassed the control and was more 1 times than control when harvesting. The fruit bagging influenced the content of the carbohydrate. The experiment indicated that the titratable acid is notably lowered in red Fuji apple after bagging. It was lowered in the content of various soluble sugar ( total sugar, reducing sugar, sucrose, fructose, glucose) and the starch to some extent. But there was the same change trend between bagging and control.
