Abstract：In the period of Chinese cabbage-pak-choi two leaves,the ef mutant plants were sprayed by different concentration of GA3 and PP333 treatments,respectively.Based on investigation of plant height,plant width,number of leaves and the dates of plant heading,budding and flowering,G-POD and APX activities were tested.Results showed that there was very significant difference in plant height，G-POD and APX activity by the treatment with GA3 and PP333,but no difference in plant width and number of leaves.After the treatment with GA3,G-POD activity firstly declined then increased.But the result was just opposite by the treatment of PP333.APX activity declined firstly and then increased by the treatment of GA3 and PP333.Different treatments had significant affects on flowering date of ef mutants,GA3 treatment could stimulate their blossoming,while PP333 treatment could delay their blossoming.
