Effect of mycorrhizal inoculation on growth, nitrogen fixation, and nutrient uptake in Cicer arietinum (L.) under salt stress

摘要: Most legumes in natural conditions form a symbiosis with arbuscular mycorrhizal (AM) fungi. AM fungi saline soils have been reported to improve salinity tolerance and growth plants. In the present study, interaction between fungus, Glomus mosseae, stress relation plant growth, nitrogen fixation, nutrient accumulation was evaluated Cicer arietinum (L.) (chickpea). Two genotypes of chickpea (Pusa-329, salt tolerant, Pusa-240, sensitive) were compared under different levels without inoculations. Salt resulted noticeable decline shoot root dry matter accumulation, resulting shoot-to-root ratio (SRR) all However, Pusa-329 found be more tolerant than Pusa-240. plants exhibited better biomass stressed as well unstressed conditions. Mycorrhizal infection (MI) reduced increasing levels, but dependency (MD) increased, which evident Salinity marked nodule weights, whereas surge number recorded. Nitrogenase activity concentrations. had considerably higher numbers, nitrogenase both nonsaline environments. comparatively lower Na+ concentration K+ Ca2+ concentrations Although (N) phosphorus (P) contents declined salinity, N P Plants inoculated mosseae fixation stress.
