摘要
本文针对国内外有关盐性条件下的丛枝菌根相关报道,概述了自然盐性土壤中的AM真菌,盐胁迫对丛枝菌根的影响作用以及盐胁迫下AM菌根对植物的影响。许多研究表明,在自然盐性土壤中存在着大量的AM真菌,土壤盐度影响着菌根的形成和发育;在盐性环境下,AM真菌能促进植物的生长和对矿质营养的获取,提高植物的耐盐性。因此,菌根对盐碱土壤中植物的生长有着潜在的促进作用,植物菌根修复技术将助于盐碱土壤的开发、改良。
Based on the reports of mycorrhiza can improve plants' tolerance to salt,the influence of salt stress on AM and the effect of AM on plants were summarized here. The reports investigated the emergence of AM in natual, which are in great deal, and the salinity of soil effect the formation and the growth of AMF. In addition,AM can improve the growth and mineral acquisition ,thus enhance the salinity tolerance of mycorrhizal plants. Therefore mycorrhiza have the potiential function for increasing plants' growth, and the mycorrhizal restoration technology would make for the exploiture and meliorative of saline-alkaline soils.
