摘　　要：在温室中培育烟草幼苗至9叶1心时,在第9叶片上涂抹不同浓度的杀虫剂毒死蜱100μL,24 h后测定烟草幼苗MDA含量和抗氧化酶的活性。结果表明,毒死蜱引起烟草幼苗丙二醛(MDA)含量降低,抗氧化酶超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、抗坏血酸过氧化物酶(APX)、谷胱甘肽过氧化物酶(GPX)活性下降,其对烟草幼苗安全。Different concentration of chlorpyrifos were applied to the ninth leaf of the tobacco seedlings by daubing which were cultivated under greenhouse condition at 9 leaves with 1 core stage, and the content of MDA and activities of antioxidant enzyme were tested after 24 h. The results showed that chlorpyrifos reduced MDA content of tobacco leaves, and decreased the activities of CAT, APX and GPX. And it is safe to tobacco seedlings.
