摘要
目的研究在不同浓度丙溴磷作用下,油菜的超氧化物歧化酶(SOD)及过氧化产物丙二醛(MDA)的变化。方法SOD和MDA的活性分别采用氯化硝基四氮唑蓝(NBT)光照还原法和硫代巴比妥酸法。结果两种浓度的丙溴磷均诱导了油菜SOD活性,MDA含量明显高于对照组,并随作用时间延长,逐渐减少。结论在油菜遭受丙溴磷胁迫初期SOD和MDA即变化显著,可作为丙溴磷迫胁油菜比较敏感的生物指标。
Objective An experiment was carried out to study the effects of different profenofos levels on the activities of superoxide dismutase(SOD) and the content of malondialdehyde(MDA) in Rapes.Methods The activities of SOD and the content of MDA were determinated by visible spectrophotometry.Results The results showed that the activities of SOD and the content of MDA were all increased but and reduced along with the response time.Conclusion The activities of SOD and the content of MDA which were all highly impro...
