Abstract

In order to investigate the influence of exogenous substances on the fruit quality of peach,certain concentrations of Ca(NO3)2,KH2PO4,glutanic acid,GA3,6-BA and ABA were sprayed on the leaves of peach variety Xiahui 6 at the second fruit expansion period.All 6 kinds of exogenous substances improved fruit weight.ABA and KH2PO4 increased fruit brightness.ABA enhanced the soluble solid contents,the ratio of soluble sugar to titratable acid and the flesh firmness.GA3,6-BA and ABA significantly improved the coloring of peach fruit.Compared with CK(water treatment),all exogenous substances treatments significantly raised anthocyanin,increased POD activities and decreased PPO activities.100 mg/L ABA had better effect on improving fruit quality.
