摘要
通过水培试验,研究了La对与油菜抗病性相关的过氧化物酶(POD)、过氧化氢酶(CAT)、超氧化物歧化酶(SOD)和多酚氧化酶(PPO)酶活性以及对膜脂过氧化产物丙二醛(MDA)含量的影响。结果表明:喷施0.3mg·kg-1的La3+油菜叶绿素含量显著增加,POD,CAT,SOD和PPO活性增高,MDA含量降低,但可溶性蛋白含量无显著变化。可见La具有诱导植株产生抗病性的作用。
The effects of lanthanum on the protective enzymes of rape(Brassica juncea) were studied in the solution culture experiment. The results show that when 0.3 mg·kg-1 La is sprayed, the content of chlorophyll and the activities of peroxidase(POD), catalase(CAT), superoxide dismutase(SOD) and polyphenoloxidase(PPO) increase, but the content of malondialdehyde(MDA) decrease. The content of soluble protein does not change significantly after treated.
