As compared with the chilling control,SOD(superoxide dismutase),POD(peroxidase) and CAT(catalase) activities increased while ADX(ascorbate peroxidase) activity decreased in the SA pretreatments under chilling stress.

• 的产生速率; 同时酶活性分析表明,SA预处理后水稻幼苗在低温胁迫下超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)活性较低温对照上升,而抗坏血酸过氧化物酶(APX)活性较低温对照下降。
