摘　　要：在父母本花时迥异的3个亚种间杂交粳稻组合制种过程中,采用喷施茉莉酸甲酯溶液的方式来调节不育系的花时,促使父母本花时同步,从而实现了提高异交结实率,增加制种产量的效果。In order to make the the floret opening time of both male parent and female parent fit well, a field experiment, in which the MeJA was sprayed to the female parent of 3 japonica intersubspecific hybrid rice with different floret opening time characteristics was carried out. The results showed that the MeJA can adjust the floret opening time of female parent significantly to fit the floret opening time of it＇s male parent, increase seed setting rate, and enhance the seed production yield obviously.
