- Intervention effect Salt stress decreased alfalfa growth parameters and stem extension rate.
- Intervention effect Salt stress decreased predawn leaf water potential, chlorophyll content, potassium concentration, and potassium/sodium ratio.
- Intervention effect Salt stress increased leaf sodium concentration and malondialdehyde level.
- Intervention effect Salt stress increased superoxide dismutase, catalase, and peroxidase activities in alfalfa leaves.
- Intervention effect Exogenous silicon enhanced photosynthesis parameters in salt-stressed alfalfa.
- Intervention effect Silicon enhanced predawn leaf water potential, chlorophyll content, and water use efficiency under salt stress.
- Intervention effect Silicon limited sodium accumulation in alfalfa leaves under salt stress.
- Intervention effect Silicon maintained leaf potassium concentration under salt stress.
- Intervention effect Silicon-treated plants had higher antioxidant activities under salt stress.
- Intervention effect Silicon-treated plants had lower malondialdehyde under salt stress.
- Recommendation The authors propose exogenous silicon application to improve salt tolerance of alfalfa in saline soil.
