Other claims from this paper (11)
- Intervention effect Added NaCl slowed Rhizobium growth in culture media.
- Intervention effect Some strains could not grow at 120 mM NaCl.
- Intervention effect Most Rhizobium strains survived extended exposure to saline solutions equal in concentration to sea water.
- Association Increasing moisture tension and salinity had additive effects on Rhizobium survival in soil.
- Intervention effect The soybean-Rhizobium nodule system was not greatly affected by 120 mM NaCl.
- Mechanism The main reduction in nitrogen fixation is attributed to indirect effects of salinity on leaf expansion, shoot yield potential and the sink for nitrogen.
- Intervention effect Early processes of nodule formation were extremely sensitive to NaCl in the rooting medium.
- Intervention effect NaCl at 26.3 mM added before inoculation reduced nodule number and mass by 50%.
- Intervention effect NaCl at 79.9 mM reduced nodule number, nodule mass and nitrogen fixation to less than 10% of the controls.
- Intervention effect Rhizobium reisolated from high-salt nodules did not form more nodules under saline conditions than isolates from controls.
- Recommendation High-quality irrigation water must be used during establishment of symbiotic legumes.
