Other claims from this paper (15)
- Intervention effect Salt stress significantly reduced growth and yield of both rice cultivars.
- Intervention effect Both rice cultivars failed to produce grains at 50 and 100 mM NaCl.
- Intervention effect Growth was drastically reduced at 50 and 100 mM NaCl.
- Intervention effect Exogenous proline did not compensate for the adverse effects of salt stress at 50 and 100 mM NaCl.
- Intervention effect Exogenous proline significantly increased plant growth of both rice cultivars at 25 mM NaCl.
- Intervention effect Proline increased grain yield of only the salt-sensitive rice at the same salt stress.
- Intervention effect Salt stress significantly decreased chlorophyll and ascorbate contents in both rice cultivars.
- Intervention effect Salt stress significantly decreased the straw K+/Na+ ratio in both rice cultivars.
- Intervention effect Salt stress significantly decreased guaiacol peroxidase (POX) activity in both rice cultivars.
- Intervention effect Intracellular proline content increased under salt stress in salt-sensitive rice.
- Intervention effect Intracellular proline content decreased under salt stress in salt-tolerant rice.
- Intervention effect Exogenous proline increased the K+/Na+ ratio in salt-sensitive rice at 25 mM NaCl.
- Intervention effect Exogenous proline increased antioxidant enzyme activities in salt-sensitive rice at 25 mM NaCl.
- Intervention effect Most of the measured traits were not affected by exogenous proline in salt-tolerant rice at 25 mM NaCl.
- Mechanism The authors suggest exogenous proline confers salt tolerance in salt-sensitive rice by maintaining K+/Na+ ratio and enhancing proline accumulation and antioxidant defence.
