摘要
以4个果色不同的彩色甜椒品种为试材,研究了整个生长发育过程中的果实叶绿素、类胡萝卜素、花青苷和类黄酮的动态变化。结果表明,随着果实的成熟,不同果色的叶绿素含量在转色期之前逐步增加,转色期达到最高,转色之后急剧下降;商品成熟果果色绿色、白色的类胡萝卜素含量随果实的生长逐步增加,生理成熟期达到最大值,商品成熟果果色淡黄色的类胡萝卜素含量在转色期之前逐步增加,转色之后下降;随着果实的成熟,除生理成熟果果色橙黄色的花青苷含量几乎不变外,生理成熟果果色红色的花青苷含量转色期之前逐步增加,转色之后急剧增加;不同果色的类黄酮含量在转色期之前下降,转色之后增长。相关分析表明,叶绿素含量分别与类胡萝卜素、花青苷和类黄酮极显著负相关,类胡萝卜素含量与花青苷极显著正相关,与类黄酮显著负相关;花青苷含量与类黄酮负相关,但未达显著水平。
The dynamic changes of chlorophyll, carotenoid, anthocyanion and flavonoid were conducted during growth periods with four different fruit color of color sweet pepper. The results showed that contents of chlorophyll increased gradually before changing color stage,attained the maximum at changing color stage ,then decreased ; contents of chlorophyll of the green color or white color fruit at marketable mature stage gradually increased with maturation, attained the maximum at physiological mature stage; contents of carotenoid of the yellow color fruit at marketable mature stage increased slowly before changing color stage,then decreased except contents of anthocyanion of yellow-orange of fruit at physiological mature stage changed little during growth periods; contents of anthocyanion of the red fruit at physiological mature stage in- creased slowly before changing color stage,then quickly increased,and contents of flavonoid were decreased before changing color stage,then increased gradually. The analysis of correlation showed that contents of chlorophyll had negatively significant correlation with contents of carotenoid, anthocyanion and flavonoid ; contents of carotenoid had positively significant correlation with contents of anthocyanion and negatively significant correlation with contents of flavonoid ; contents of anthocyanion had negatively but not significant correlation with contents of flavonoid.
