| 摘 要： | 采用营养液水培,研究了不同浓度（5、10、20、50、100、130 mg/L）镍处理下小麦幼苗叶片SOD、POD和CAT同工酶谱的变化。结果表明：镍处理下,小麦幼苗叶片SOD3-4、POD6-9、CAT1酶带减弱,SOD1-2、POD1-5诱导增强,镍通过影响SOD和CAT同工酶强弱而影响酶活性,通过改变POD同工酶条数和强弱来影响POD活性。

| Abstract: | The effects of Ni2+ in different concentration(5,10,20,50,100 mg/L) on isozymograms of SOD,POD and CAT in wheat(Triticum aestivum L.) seedling leaf were studied by the method of hydroponics.The results showed that under nickel treatment,the isozymograms of SOD3-4,POD6-9 and CAT1 weakened obviously compared with the control,whereas the isozymograms of SOD1-2 and POD1-5 strengthened obviously.So excess nickel affected SOD and CAT activities in wheat seedling leaf by isozymograms expression,and affected POD ac... |
