以不同浓度的吡虫啉溶液处理小麦，测定吡虫啉连续胁迫下小麦SOD、CAT活性及MDA的变化。结果表明，低剂量吡虫啉连续胁迫下，SOD活性及MDA含量表现出明显的时间效应，CAT活性变化不存在明显的时间效应。与对照相比，0．2 mg／kg吡虫啉处理后28天，SOD活性显著高于对照；药后22天，吡虫啉各浓度极显著降低MDA含量，药后28天，大多数吡虫啉浓度又极显著提高了MDA含量。
以不同濃度的吡蟲啉溶液處理小麥，測定吡蟲啉連續脅迫下小麥SOD、CAT活性及MDA的變化。結果錶明，低劑量吡蟲啉連續脅迫下，SOD活性及MDA含量錶現齣明顯的時間效應，CAT活性變化不存在明顯的時間效應。與對照相比，0．2 mg／kg吡蟲啉處理後28天，SOD活性顯著高于對照；藥後22天，吡蟲啉各濃度極顯著降低MDA含量，藥後28天，大多數吡蟲啉濃度又極顯著提高瞭MDA含量。
이불동농도적필충람용액처리소맥，측정필충람련속협박하소맥SOD、CAT활성급MDA적변화。결과표명，저제량필충람련속협박하，SOD활성급MDA함량표현출명현적시간효응，CAT활성변화불존재명현적시간효응。여대조상비，0．2 mg／kg필충람처리후28천，SOD활성현저고우대조；약후22천，필충람각농도겁현저강저MDA함량，약후28천，대다수필충람농도우겁현저제고료MDA함량。
The variation of SOD and CAT activities and MDA content in wheat were analyzed after trea-ted with different concentrations of imidacloprid.The results showed that the change of SOD activity and MDA content showed obvious time effect under the continuous stress of low-dose imidacloprid, while the change of CAT activity showed no.Compared with the control ( CK) , the SOD activity was significantly higher after trea-ted for 28 days with 0 .2 mg/kg imidacloprid;the MDA content decreased very significantly on the 22 nd day under each concentration, but increased very significantly on the 28th day under most concentrations.
