After harvest,the level of ABA and ethylene in fresh of cultivars “Baifeng”and“Jingyu”of peach raise and then decrease regularly,but the change of level in ABA is a little before that of cthylene.Nevertheless the level of GA_3 gradually decrease.The results indicate that the relation among ABA,GA and ethylene is a control factor regulating the ripening of peach fruits.
