Other claims from this paper (11)
- Intervention effect Increasing NaCl progressively reduced callus growth rate.
- Intervention effect Increasing calcium ameliorated the salt-induced reduction in growth rate.
- Observation Callus potassium concentration was lowest at the highest NaCl concentration.
- Intervention effect High calcium partially reversed the salt-induced decrease in callus potassium.
- Intervention effect Calcium decreased the callus sodium-to-potassium ratio.
- Intervention effect Callus proline concentration increased with NaCl.
- Association Without supplemental NaCl, growth and proline concentration were uncorrelated.
- Association At 150 mol m −3 NaCl, growth and proline concentration had a strong positive correlation.
- Intervention effect Increasing calcium raised callus proline concentration in both cultivars.
- Intervention effect At the highest salt concentration, increased calcium raised callus growth.
- Mechanism Proline accumulation may support cell growth only above a salt-stress threshold, depending on other protective mechanisms.
