Abstract:

The content changes of chlorophyll, carotenoid, anthocyanin, flavonoid and phenolic compounds were studied during the fruit development of Chaohong and Richuanbaisha peach, meanwhile the correlations between anthocyanins content and contents of other 4 compounds were analyzed. Results indicated that lower chlorophyll and carotenoids contents were found in Chaohong pericarp and tended to declined more quickly while a higher anthocyanins content with sharp increase. However, pigment contents in Chaohong were lower at the early stage of fruit development and increased at the late stage. Flavonoids content showed a decreasing tendency while phenolic compounds showed the same pattern with pigments. A negative correlation was observed between the contents of anthocyanin and other pigments and phenolic compounds with fewer exceptions.

Key words: Chaohong peach, Richuanbaisha peach, fruit development, pigment, phenolic compounds
