[Objective] The aim was to study the effects of magnetic field on SOD enzyme activity and root vigor of Cucumis sativus L. Seedlings. [ Method] In the simulation of the drought stress conditions, the change of SOD enzyme activity and the root vigor of Cucumis sativus L. seedlings were studied which were treated with magnetic field of different magnetic flux. [ Result] The results showed that compared with the control group, magnetic field treatment can strengthen SOD enzyme activity and root vigor of Cucumis sativus . [ Conclusion] By improving the seedling SOD enzyme activity and root activity, the magnetic treatment enhanced the seedling free radicals and the ability to absorb water, reduced the damage to the young seedlings, and improved the ability of fighting drought%[目的]研究磁场处理对黄瓜(Cucumis sativus L.)幼苗SOD酶活性和根系活力的影响.[方法]在模拟的干旱胁迫条件下,研究不同磁感应强度处理对黄瓜幼苗SOD酶活性和根系活力的影响.[结果]与对照组相比,磁场处理能增强黄瓜幼苗SOD酶活性和根系活力.[结论]磁场处理通过提高幼苗SOD酶活性和根系活力,增强了幼苗清除体内自由基的能力和吸收水分的能力,减轻了干旱对幼苗的伤害,提高了幼苗的抗旱能力.
