“…Reduction of N 2 -fixing activity by salt stress is usually attributed to a reduction in respiration of the nodules (Kenenil et al, 2010). Additionally, the salt-induced distortions in nodule structure could be the reason for the decline in the N 2 fixation rate by legumes subjected to salt stress (Fahmi et al, 2011). The depressive effect of salt stress on N 2 fixation by legumes is directly related to the salt-induced decline in dry weight and N content in the shoot (Zahran, 2001).…”

“…Indeed, our data showed that application of salt treatment decreased the biomass of nodules. Tejera et al (2004) and Fahmi et al (2011) noted that salt stress inhibits nodule formation by the inhibition of the initial steps of rhizobia-legume symbiosis. In Phaseolus vulgaris L., the concentration of 50 mM of NaCl caused a decrease of growth (Gama et al, 2007).…”

The present work was a study on the adverse effects of salinity on growth, nodulation, and some physiological parameters in 4 symbiotic combinations involving 2 Moroccan alfalfa (Medicago sativa L.) populations (Demnate and Tata) and 2 rhizobial strains (rhLAr 1 and rhLAr 4). The experiment was conducted in the greenhouse at 32/22 °C day/night, 50%-80% relative humidity, and a photoperiod of 16 h. The seedlings were separately inoculated with suspensions of 2 rhizobial strains and grown under 2 NaCl treatments, 0 mM (control) and 100 mM (salt stress), in plastic pots filled with sterile sand and peat at 9/10 and 1/10 ratios, respectively. The salt stress was applied for 5 weeks and some agro-physiological and biochemical parameters related to salt tolerance were assessed. The results showed that salinity significantly reduced the height of plants, their dry biomass, and nodulation. This constraint has also negatively affected the relative water content of leaves, the membrane permeability, the stomatal conductance, the maximum quantum yield of photosystem II, and the chlorophyll contents. Comparison among the symbiotic combinations tested showed that their behavior was significantly different. Plants inoculated with rhizobial strain rhLAr 4 were more tolerant to saline conditions. Their tolerance was associated with the maintaining of adequate levels in terms of physiological and biochemical parameters studied.

Soil salinity is one of the most severe factors limiting growth and physiological response in cowpea plants. In the present study, the effect of rhizobacterium strains BR2 and BR3 on the growth of cowpea (Vigna unguiculata L.) varieties-Pusa Sukomal and RC101-tolerance to 0, 25, 50, and 75 mM concentrations of NaCl salinity was evaluated. The rate of growth, in general, was high in plants irrigated with 25 mM NaCl saline water as compared to control, and thereafter, the growth reduced with increase in salinity concentrations. The results revealed that treating the seeds with rhizobacteria accompanied by NaCl salinity increased growth parameters of the cowpea plant as compared to the seeds irrigated with sodium chloride alone. Treatment with rhizobacteria mitigated the harmful effect of NaCl, and the growth was significantly better than the plants growing in saline water without rhizobacterium inoculation. The overall performance of Pusa Sukomal with BR3 strain was found to be better than the other combinations tested. Flowering in field plants started within 45 days of sowing, and the seeds in plants irrigated with saline water, in the presence of rhizobacterium, were found to be healthy as compared to control seeds. Seed protein profile was analyzed by SDS PAGE gel studies.

“…Furthermore, Younesi et al (2013) reported that nodulation was completely inhibited under salt stress condition. In this respect, Fahmi et al (2011) reported that the increase of seawater concentration (salinity level) decreased the average number of nodule through nodule formation by the inhibition of initial steps of Rhizobiumlegume symbioses. In this concern, the variation in nodulation could be due to low rhizobial density, incompatibility of the rhizobia and edaphic factors that hinder the effecttiveness of the rhizobia.…”

The efficiency of eight Rhizobium leguminosarum strains isolated from root nodules of Faba bean plants which were collected from different Governorate in Egypt has been examined. After inoculation of faba bean seeds with each Rhizobium strain individually, we measured the growth promotion, nodule formation and plant protein profile under different concentration of sodium chloride salt stress. The interactions between salt tolerant and sensitive faba bean cultivars and Rhizobium strains under NaCl stress were found to be significant. Nitrogen fixation efficiency varied among the eight Rhizobium strains. The protein profile using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) for both faba bean cultivars revealed that Rhizobium strains numbers RL1, 2, 4 and RL 8 showed high level of salt tolerance under 40 and 80 mM NaCl in both faba bean cultivars. Rhizobium strains improved the salt tolerance, as is clearly observed in number of nodules and the amount of N 2 fixation. It is known that stress affects the growth, metabolic activity and symbiotic efficiency of Rhizobium with faba bean plant but in this study we found that Rhizobium strains numbers RL2 and RL 3 showed high efficiency of N 2 fixation and growth promotion in both faba bean cultivar.
