摘要：

为探讨光照是否影响红肉桃果实果肉着色，以青岛市地方红肉桃品种“大把撸”为材料，研究了不同套袋处理对着色后红肉桃果肉糖酸及色素尤其是花青苷含量变化的影响。结果表明：套袋明显抑制了果肉红色的形成；果实摘袋见光后花青苷合成能力得到恢复；套袋也降低了红肉桃果肉可滴定酸、可溶性糖、叶绿素和类胡萝卜素含量，由此证明红肉桃果实果肉红色形成在很大程度上受光照影响。

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.
