接种摩西球囊霉对盐胁迫条件下盐地碱蓬叶片SOD和CAT活性的影响

摘要

[Objective] Under salt stress condition, effects of inoculation of arbuscular mycorrhizal fungi Clomus mosseae on SOD and CAT activity in Suaeda salsa seedlings under salt stress were studied. [Method] There were 2 NaCl levels, namely 0 and 400 mmol/L and each NaCl contained 2 treat-ments, one is inoculated by Glomus mosseae and the other is control. The growths of Suaeda salsa, SOD and CAT activities as well as MDA content in leav-es was determined. [Result] Under salt stress condition, Glomus mosseae could increase the growths of Suaeda salsa, SOD and CAT activities in leaves and decreased MDA content in leaves. [Conclusion] It preliminarily demonstrated that Arbuscular Mycorrhizal (AM) Fungi could increase salt resistance of Suaecla salsa by increasing the activities of SOD and CAT as well as alleviating membrane injury.
