Abstract
In order to discuss the influence of exogenous substances(ABA)on the fruit quality of peach,ABA were sprayed on leaves.The results showed that ABA could not significantly increse fruit size and fruit weight.Compared with contrast,ABA improved the contents of soluble solid,and significantly increased the content of soluble sugar and the ratio of soluble sugar to titratable acid.Anthocyanin of peel,anthocyanin/carotenoid,h and a/b were remarkablely increased after spraying with 25 mg/L ABA in the second fruit expansion period(65 days after full bloom).This indicated that 25 mg/L ABA had better effect on increasing fruit quality than other treatments.
