摘　　要：[目的]研究β-氨基丁酸(简称BABA)诱导水稻穗瘟病抗性对活性氧代谢的影响。[方法]以超产2号高感病品种为材料,测定喷施BABA后各处理过氧化氢酶(CAT)、超氧化物歧化酶(SOD)及丙二醛(MDA)变化情况。[结果]喷施BABA后,水稻植株的CAT、SOD活性增强,水稻植株的MDA含量相对增加,对水稻稻瘟病的抗性增强。[结论]BABA是通过影响水稻植株的活性氧代谢水平从而达到抗病的目的。该药剂对环境安全,具有高效诱抗作用,可在生产上加以推广。[Objective] This study was to understand the effects of β-amino butyric acid（abbreviated as BABA） induced rice blast resistance on reactive oxygen metabolism.[Method] Using the cultivar Chaochan No. 2 highly susceptible to disease as experimental material, the Changes of catalase（CAT） and superoxide dismutase（SOD） activities in rice treated by BABA were investigated.[Result] In rice plant treated by BABA, the activities of CAT and SOD increased, meanwhile the MDA content also rose to some extent, resulting in the disease resistance to rice blast.[Conclusion] By influencing reactive oxygen metabolism, BABA endows rice plant.with resistance to rice blast. BABA is safe to environment and has highly resistance-inducing capacity, it could be generalized in production.
