摘 要: | [目的]于盐胁迫条件下,研究接种摩西球囊霉对盐地碱蓬生物量、MDA含量以及SOD、CAT活性的影响。[方法]设0、400mmol/L 2个NaC l水平,每个水平下设接种和不接种(对照)摩西球囊霉2个处理。测定各处理下盐地碱蓬的生长量和叶片SOD、CAT活性,以及叶片MDA含量。[结果]盐胁迫条件下,接种摩西球囊霉显著增加了盐地碱蓬的生长量和叶片SOD、CAT活性,而降低了叶片MDA含量。[结论]初步证实了AM真菌提高盐地碱蓬抗盐性是通过增加SOD和CAT活性、降低膜伤害来实现的。

Abstract: | [Objective] Under salt stress condition,effects of inoculation of arbuscular mycorrhizal fungi Glomus 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 every NaCl contained 2 Glomus mosseae treatments which were inoculated Glomus mosseae and control treatment.The growths of Suaeda salsa,SOD and CAT activities as well as MDA content in leaves 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 Suaeda salsa by increasing the activities of SOD and CAT as well as decreasing membrane injury. |
