Abstract: In order to make up a standard procedure for safe use of gibberellic acid in pear,the field experiment of gibberellic acid efficacy was carried out according to weight 37.5mg/fruit. Gibberellic acid residues were quantified by HPLC. The results showed that the dissipation of gibberellic acid in the pear was rapid, with half-lives of 9.8-13.6d. As time went on, the residual contents of gibberellic acid in the pear and soil decreased, which accorded with the first-order kinetics equation.
