Arbuscular mycorrhizal (AM) fungi play an important role in improving the plant tolerance to salt stress. In the present study, we investigated the influence of AM fungi inoculation on various physiological, biochemical and nutritional aspects of pea grown under salt stress. The AM fungi inoculation successfully reduced the negative effects of salinity by improving the antioxidant enzyme system, a greater accumulation of compatible organic solutes, a higher content of photosynthetic pigment and a balanced uptake of nutrients, which resulted in higher growth and yield. Seed yield was found to be significantly higher by ~ 24, 40 and 54% in T2 (Rhizoglomus intraradices), T3 (Funneliformis mosseae and R. intraradices) and T4 (Rhizoglomus fasciculatum and Gigaspora sp.), respectively, as compared to nonmycorrhizal plants. Overall, a mixed application of R fasciculatum and Gigaspora sp. was superior to other mycorrhizal treatments, which can be attributed to specific compatibility relationships or functional complementarity that exists between symbionts.

丛枝菌根真菌通过调控豌豆(Pisum sativum L.)抗氧化酶系统、光合途径和离子平衡介导耐盐性
丛枝菌根(AM)真菌在提高植物对盐胁迫的耐受性方面发挥着重要作用。在本研究中,我们研究了 AM 真菌接种对盐胁迫下豌豆的各种生理、生化和营养方面的影响。AM真菌接种通过改善抗氧化酶系统、更大的相容有机溶质积累、更高的光合色素含量和营养物质的平衡吸收成功地降低了盐分的负面影响,从而提高了生长和产量。发现 T 2(Rhizoglomus intraradices )、T 3(Funneliformis mosseae和与非菌根植物相比,R. intraradices ) 和 T 4 ( Rhizoglomus fasciculatum和Gigaspora sp.)。总体而言, R fasciculatum和Gigaspora sp的混合应用。优于其他菌根处理,这可归因于共生体之间存在的特定相容关系或功能互补性。
