Other claims from this paper (10)
- Intervention effect Salinity of 25 mM and 50 mM NaCl significantly decreased pods per plant, and the fresh and dry weight of pods per plant, relative to tap water.
- Intervention effect Salinity of 25 mM and 50 mM NaCl significantly decreased shoot dry weight and photosynthetic pigment level relative to tap water.
- Intervention effect Potassium at 150 mg K2O kg-1 soil mitigated the harmful effects of salinity on common bean yield and photosynthetic pigment content.
- Intervention effect Salinity significantly increased proline, free amino acid and soluble carbohydrate concentrations relative to control plants.
- Intervention effect Salinity significantly increased peroxidase and polyphenol oxidase activities relative to control plants.
- Intervention effect Potassium treatment K2 significantly increased peroxidase and polyphenol oxidase activities relative to control plants.
- Intervention effect Both RILs showed a decrease in phenolic compound concentrations due to salinity and/or K2 application compared with control plants.
- Association The K+:Na+ ion ratio decreased significantly as salinity level increased.
- Intervention effect Potassium treatment K2 significantly increased the K+:Na+ ion ratio.
- Mechanism The authors suggest K+ ions mitigate salinity effects by enhancing pigments, antioxidant enzymes, osmoprotectants and the K+:Na+ ratio, improving plant performance.
