摘要
丛枝菌根真菌（Arbuscular mycorrhizal fungi，AMF）是自然界广泛存在的一种内生菌根，能够提高植物的耐盐能力。本文概述了盐性土壤中AM真菌与宿主植物的互作关系及AM真菌提高植物耐盐性的作用机制。盐渍化系统中存在大量AM真菌，并且土壤盐度影响着菌根的形成和发育；AM真菌可以改善宿主植物的矿物质营养元素吸收情况，提高宿主植物的水分吸收，增强宿主植物的抗氧化酶系统活力，进而提高植物的耐盐性。在以上基础上，还对本领域的研究前景提出了设想，为盐碱地改良提供参考依据。
Arbuscular mycorrhizal fungi （AMF） has been known to occur naturally in saline environ ments as a vesicular-arbuscular mycorrhizal fungi （VAM） that can improve plant salt tolerance. Based on the reports of salt tolerance of myeorrhizal plants, the interrelation between AMF and host plant and the mecha nism of AMF in alleviation of salt stress were summarized here. This paper investigated the influence of salt tolerance on AMF＇s distribution, formation and growth; AM fungi can enhance the salt tolerance of host plants through enhancing nutrient acquisition, amplifing water acquisition ability and increasing the activi ties of antioxidant enzymes. This review identifies certain areas which need further exploration and gives useful information for the development of saline soil improvement.
