Abstract

One abiotic barrier that can inhibit the growth of soybean plants is salt stress. This study was conducted to describe the role of tripartite symbiosis between Glosum mosseae and Rhizobium japonicum on plant tolerance grown under salt stress conditions using soybean as a plant tested. There were two conditions of salinity (0 mM NaCl and 200 mM NaCl) with four treatments, namely, 1. non-inoculant plants, 2. plants inoculated with rhizobium, 3. plants inoculated with mycorrhizae and 4. plants inoculated with rhizobium and mycorrhizae. The results showed that plant tolerance to salt stress increased in inoculation with mycorrhizae and rhizobium compared to non-inoculant plants. The tolerance increased along with the increase in the absorption of P and N which had an impact on increasing plant biomass. The tripartite symbiotic between soybeans, G. mosseae and R. japonicum revealed positive effects on the parameters of mycorrhizal colonization, root nodules, plant biomass, microbial dependency, stress tolerance index and nutrient uptake compared to uninoculated plants or inoculated plants with Glomus mosseae or inoculated plants with R. japonicum only. It reflected that tripartite symbiosis was more effective than single inoculation in salt stress conditions.
