Abstract: Changes of endogenous ABA content during fruit development as well as the effect of exogenous ABA and Fluridone treatment on ripening of detached peach (Prunus persica L.‘Hakuho’) fruit in the late development period were studied in order to discuss relationship between ABA and fruit ripening of peach. Accumulation of endogenous ABA during late period of peach development triggered peach fruit ripening, and the peak of endogenous ABA content initiated the fruit ripening process. The treatment of exogenous ABA promoted ripening and senescence process of detached peach fruits, and Fluridone treatment inhibited biosynthesis of endogenous ABA and ethylene production and delayed fruit softening. Ethylene maybe acted as an auxiliary factor to influence fruit ripening and senescence process.

Key words: Prunus persica L. Batsch, abscisic acid, ethylene, ripening
