ABSTRACT Salinity is one of the major threats to an agriculture production system and limits crop growth and productivity. Arbuscular mycorrhizal fungi (AMF) form a mutualistic association with majority of land plants and play important role in stress tolerance. In the present study, effect of three mycorrhizal treatments, i.e., single-species AMF (Rhizoglomus intraradices), formulated AMF (Funneliformis mosseae and R. intraradices), and multispecies AMF (Rhizoglomus fasciculatum and Gigaspora sp.) along with control (nonmycorrhizal) on growth, yield performance, and metabolic changes in pea crop under salinity stress was examined in completely randomized design with four replications. The results revealed that AMF inoculation mitigated negative effects of salinity in pea due to higher nutrient uptake, accumulation of compatible osmolytes, and lower cellular leakage of electrolyte which in turn enhanced biomass production, chlorophyll synthesis, yield, and growth attributes. Overall, consortium-based application of R. fasciculatum and Gigaspora sp. was found most suitable approach to ameliorate the salt stress in pea crop and enhanced the yield by ~11%, 24%, and 54% than single-species, multispecies, and control treatments, respectively. The variation in results under different mycorrhizal treatment might be due to specific compatibility relationships that exist between symbionts.

接种丛枝菌根真菌减轻豌豆盐胁迫的效果

摘要 盐度是农业生产系统的主要威胁之一，限制了作物的生长和生产力。丛枝菌根真菌 (AMF) 与大多数陆生植物形成共生关系，并在胁迫耐受中发挥重要作用。在本研究中，三种菌根处理的效果，即单物种 AMF（根内根瘤菌）、配制的 AMF（Funneliformis mosseae 和 R. intraradices）和多物种 AMF（Rhizoglomus fasciculatum 和 Gigaspora sp.）以及对照（非菌根）盐胁迫下豌豆作物生长、产量表现和代谢变化的影响以完全随机的设计进行了四次重复研究。结果表明，AMF 接种减轻了豌豆中盐度的负面影响，因为它具有更高的养分吸收、相容渗透物的积累、和更低的细胞电解质泄漏，这反过来又提高了生物质产量、叶绿素合成、产量和生长属性。总体而言，R. fasciculatum 和 Gigaspora sp. 的基于联盟的应用。发现最适合改善豌豆作物盐胁迫的方法，与单种、多种和对照处理相比，产量分别提高了约 11%、24% 和 54%。不同菌根处理下结果的差异可能是由于共生体之间存在特定的相容性关系。发现最适合改善豌豆作物盐胁迫的方法，与单种、多种和对照处理相比，产量分别提高了约 11%、24% 和 54%。不同菌根处理下结果的差异可能是由于共生体之间存在特定的相容性关系。发现最适合改善豌豆作物盐胁迫的方法，与单种、多种和对照处理相比，产量分别提高了约 11%、24% 和 54%。不同菌根处理下结果的差异可能是由于共生体之间存在特定的相容性关系。
