【摘要】 在室内水泥池以预接种育苗移栽的方法,研究菌根菌漏斗孢球囊霉（Glomus mosseae）和紫色马勃（Calvatia Lilacina）对甘蔗抗旱性的影响。结果表明,菌根菌接种后降低了蔗叶水分胁迫下的活性氧（O₂^-）产生速率,提高了超氧物歧化酶（SOD）、过氧化氢酶（CAT）活性和谷胱甘肽（GSH）的含量,活性氧清除能力增强,减少了活性氧的积累及由此引发的膜脂过氧化,延缓了质膜透性的增加和膜结合酶Mg²⁺—ATP酶和Ca²⁺—ATP酶活性的提高,甘蔗耐旱性得到一定程度增强。菌根菌接种处理以漏斗孢球囊霉、紫色马勃另加固氮菌（Azotobater sp.）联合三接种,抗旱效果明显优于单接种和双接种。更多还原

【Abstract】 Effects of G. Mosseae and C. Lilacina on drought-resistance of sugarcane were carried out in greenhouse. Sugarcane seedlings were preinoculated with mycorrhiza fungus and then transplanted to pots. It was indicated that inoculations with mycorrhiza fungus led to the increase of drought-resistance of the plant. The accumulation of active oxygen and the peroxidation, which resulted in the raising of plasma permeability and the activities of Mg2+-ATPase and CA2+-ATPase,were lessened with the decrease of O2- production rate and the enhancement of active oxygen scavenger capacity such as the increase of SOD and CAT activity and GSH content. The results also showed that to enhance the drought-resistance of sugarcane affected by water stresses .combinative inoculation with G.mosseae.C-lilacina and Azotobac-ter sp. was better than their single or double inoculation,respectively.更多还原
