Other claims from this paper (6)
- Intervention effect High Na(+) reduced faba bean growth.
- Intervention effect High Cl(-) reduced faba bean growth more than Na(+).
- Intervention effect Increasing soil NaCl raised Cl(-) concentration more than Na(+) concentration.
- Mechanism High Cl(-) reduced photosynthetic capacity and quantum yield in faba bean, with chlorophyll degradation proposed as an explanation.
- Mechanism High Na(+) disrupted K(+) and Ca(2+) nutrition and stomatal regulation, depressing photosynthesis and growth.
- Recommendation The authors suggest that Cl(-) toxicity may have been underestimated as a cause of growth and yield loss under salinity.
