氧乐果和吡虫啉对小麦过氧化物酶、谷胱甘肽还原酶及过氧化氢酶活性的影响
Effects of imidacloprid and omethoate on the activity of peroxidase,glutathione reductase and catalase in wheat seedlings
摘要
Abstract
In order to examine the effects of insecticides on the antioxidizability of wheat, the activity of peroxidase ( POD ), glutathione reductase ( GR ) and catalase ( CAT ) in wheat seedlings were investigated during 144 h after treatment with imidacloprid and omethoate. The results showed that,comparing with that of the control, the activity of POD in wheat seedlings decreased significantly after being treated with 400,800 and 1 600 mg/L omethoate for 24 h respectively, and the activity of CAT decreased 32.9％ after being treated with 1 600 mg/L omethoate for 6 h. After being treated by 400,800 and 1600 mg/L omethoate for 144 h, the activity of GR in wheat seedlings decreased significantly.When wheat seedlings were treated with 25,50 and 100 mg/L imidacloprid respectively, only the activity of POD of wheat seedlings increased 65.0％ after being treated with 50 mg/L imidacloprid for 12 h comparing with that of the control. The results showed that activity of POD, GR and CAT in wheat seedlings were influenced by the types of insecticides, as well as the concentration of insecticides and treatment time of insecticides.关键词
