据《果树学报》2014年第4期《脱落酸和吡效隆可以改善荔枝果皮的着色情况》(作者魏永赞等)报道,以“桂味”荔枝为试材,喷施ABA和CPPU后,对果皮色泽、色素含量和花色素苷合成相关结构基因的表达规律进行分析。结果表明,荔枝果实着色过程中,叶绿素含量降低,花色素苷含量增加,色素角度逐渐降低;喷施ABA促进了花色素苷的积累,加速了叶绿素含量和色角度的降低,而CPPU则起了相反的作用;结 According to the “fruit tree” in 2014 the fourth period “abscisic acid and piperon can improve the litchi peel coloring” (authorWeiYongZan et al.) Reported, “cinnamon ” lychee as the test material, spraying ABA and CPPU , The peel color, pigment content and anthocyanin synthesis related structural gene expression analysis. The results showed that the content of chlorophyll decreased, the anthocyanin content increased and the pigment angle decreased gradually during the litchi fruit coloring. The application of ABA promoted the accumulation of anthocyanin, accelerated the decrease of chlorophyll content and color angle, while CPPU played an important role Opposite effect
