摘要/Abstract

摘要： 杂交水稻早衰组合威优49（V49）和后健组合威优35（V35）于始穗和齐穗时分别喷施赤霉素（GA3）后，其剑叶中超氧化物歧化酶（SOD）活性和过氧化物酶（POX）活性增高，早衰组合V49增加更为明显。两组合剑叶中叶绿素含量均有所降低，早衰组合降低的幅度小于后健组合。GA3处理后两组合上述指标的差异在齐穗以后更加显著。GA3使两

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
