Abstract
The residues of forchlorfenuron(CPPU) and gibberellic acid(GA3) in grape fruit(cv.Summer Black) and their effects on fruit quality were studied.Results showed that 25 mg·L-1 GA3+5 mg·L-1 CPPU treatment could obviously improve diameter and length of grape fruit than others.CPPU or GA3 level in grape fruit gradually decreased during development,and exogenous GA3 treatment had no effects on the changes of endogenous GA3 in grape fruit.The dissipation rate of CPPU in grape treated with 25 mg·L-1 GA3+5 mg·L-1 CPPU reached 90% higher after 15 days of treatment.CPPU levels after 10 days of treatment was below maximum residue limit(0.03 mg·kg-1) of USA,and GA3 residue below MRL(0.2 mg·kg-1) of USA and Japan after one day of treatment.All treatments increased total soluble solids content and decreased titratable acid content.GA3 treatment could significantly enhance total anthocyanin content of grape peel,but CPPU treatment inhibited it.This study will provide reference for the security production of grape fruit.
