摘要
于幼果期和果实转色前对红肉脐橙用不同浓度的外源ABA和GA_3处理,分析了处理对红肉脐橙果皮着色的效应。结果表明:红肉脐橙果皮叶绿素总量于7月25日出现最大值(0.116mg/gFW);总类胡萝卜素含量于12月25日达到最大值(0.029mg/g FW);外源ABA处理后加速果皮叶绿素的降解,但也抑制了果皮类胡萝卜素的积累;GA_3处理后延缓了果皮叶绿素的降解,并同样抑制了果皮类胡萝卜素的积累,阻碍了果皮类胡萝卜素的合成。
Different concentration of ABA and GA3were applied to Cara Cara Orange at young fruit formation and before fruit coloration, and their effect on fruit coloration was analyzed. The results showed that total content of chlorophyll and carotenoid in peel of Cara Cara Orange reached their maximum（0. 116mg/g FW and 0. 029mg/g FW）at July 25 and December 25, respectively. Exogenous ABA treatment accelerated the decomposition of chlorophyll in fruit peel, while inhibited the accumulation of carotenoid. GA3 treatment delayed the decomposition of chlorophyll and inhibited the synthesis of carotenoid.
