Abstract:

Qingdao local red-fleshed peach variety “Dabalu” was used to explore if the red color formation in red flesh needs sun light directly. Anthocyanin content in red flesh and other fruit quality attributes were measured with bagged and exposed fruits. The results showed that the red color formation was inhibited greatly by bagging . The ability of anthocyanins synthesis could restore after bag-moving. Bagging also reduced the content of acid, sugar, carotenoid and chlorophyll. It is proposed that red color formation in the flesh of red-fleshed peach requires sun light in some ways.
