摘　　要：用不同场强的电场处理油葵品种的种子,于二叶一心期进行干旱胁迫,然后进行超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)的活性及膜脂过氧化产物(丙二醛MDA)的含量的测定。结果表明:电场处理组SOD、POD、CAT均高于对照组,而MDA低于对照组。可以认为,静电场处理使膜结构与功能在干旱胁迫下得到保护,从而提高了油葵的抗旱性,不同电场强度对油葵品种的影响效果不同。The electric field with different density is used to treat the seed of different oil sunflower(Helianthus annuus L.)varieties. The oil sunflower seedlings with two leaves are treated under waterstress. The activity of superoxide dismutate(SOD), catalase(CAT) and peroxidase(POD) are higher than control treatment. The content of malondialdehyde(MDA) is less than control treatment. Electric treatment can protect the function and structure of membrane and enhance the droughtresistance of oil sunflower. Different density of electric field has different effect on different oil sunflower varieties. 
