红肉桃果实发育过程中色素含量及PAL活性的变化
Changes of pigments content and PAL activity of blood-flesh peach during fruit development
摘要
Abstract
Studied on the changes of pigments content and phenylalanine ammonialyase（PAL）activity of blood-flesh peach during fruit development and analysed the correlation of their changes.The results indicated that the chlorophyll contents and the carotenoid contents decreased straight during fruit development in both skin and flesh of the blood-flesh peach.Anthocyanin appeared during mature period,and the contents of anthocyanin increased gradually both skin and flesh.The maximum value of anthocyanin in the flesh and skin of blood-flesh peach were 27.8 and 48.73mg/100g·FW respectively.The changes of PAL activity in peach skin and flesh fluctuated,and decreased a little druing fruit development.Correlation analysis showed that anthocyanin content changes were remarkably and negatively correlated with chlorophyll in blood-flesh peach.Remarkably,there was a positive relationship between anthocyanin content and PAL activity in the flesh of ＂Tianxianhong＂ in maturation period.We concluded that the decrease of chlorophyll content led to the increase of anthocyanin,PAL was the key enzyme which precipitated the synthesis of anthocyanin in blood-flesh peach.关键词
