Abstract: The activities of superoxide dismutase (SOD) and peroxidase (POX) in the flag leaves increased after spraying gibberellin acid (GA3) for both the early senescent hybrid rice combination Wei-You 49(V49) and the late senescent (hybrid rice) combination Wei-You 35(V35) at heading period. Greater effect

Key words: SOD, POX, GA3, Early senescence, Hybrid rice
