摘要: 研究外源GA3 处理对柑橘‘红柿柑’果皮内源激素、叶绿素、类胡萝卜素含量变化的影响,
并探讨其与色泽变化的关系。结果表明: 外源GA3 处理较对照提高了果皮GA3 、ZT 的水平, 抑制了叶绿素下降和类胡萝卜素、β-隐黄质的合成与积累, 最终表现为柑橘果实色泽发育受阻。

Abstract: Effects of exogenous GA3 (100mg/ L) treatment on changes of endogenous hormone , chlorophyll , carotenoid content in peel of citrus fruit were investigated and their possible connections with changes in color and
lustre of citrus fruit were also examined. The results showed that GA3 treatment had little effect on ABA content , however , it inhibited decreasing of endogenous GA3 and ZT content , correspondingly , it delayed chlorophyll degradation and inhibited orange carotenoidβ-cryptoxanthin biosynthesis and acumulation that led to repress development
color and lustre.

Key words: Citrus, GA3, Chlorophyll, Carotenoid, Color and lustre
