%X We studied the effect of different concentrations and treatment time of Methyl jasmonate(MJ) ongenistein production in adventitious roots. The concentrations and treatment time of MJ had a significant effect on the content of genistein in pigeon pea adventitious roots. When the concentration of MJ was 100 &mu;mol&middot;L<sup>-1</sup>, and the treatment time was 48 h, the content of genistein was the highest(1.38 mg&middot;g<sup>-1</sup>), which was 4.03 times higher than that of the control. We studied the effect of MJ(100 &mu;mol&middot;L<sup>-1</sup>) on the antioxidant system inpigeon pea adventitious roots.The adventitious roots treated with MJ appeared obvious oxidative stress, the contents of O<sub>2</sub><sup>-</sup>, H<sub>2</sub>O<sub>2</sub> and MDA increased significantly, and the activities of SOD and POD also increased significantly. However, the increase of antioxidant enzyme activity couldnot eliminate the oxidative stress inpigeon peaadventitious roots, leding to the improvement of secondary metabolites synthesis.
