Effect of exogenous GA(0.1 mg·L~(-1)application on early seedling growth of the dwarf cucumber, namely D0462, was studied. The chlorophyll content and the activities of IAA oxidase, a-amylase, G-POD, SOD in hypocotyl and leaves were compared between control group and treatment group with GA. The results showed that the chlorophyll content and the activities of SOD, G-POD decreased, the activities of a-amylase increased, the activities of IAA oxidase decreased at first and then increased.
