Other claims from this paper (11)
- Intervention effect NaCl inhibited reed growth in a concentration-dependent manner.
- Intervention effect NaCl increased proline accumulation.
- Observation Reed salt tolerance reached a limit at about 200 m m NaCl.
- Intervention effect Salt stress increased free proline content.
- Intervention effect Salt stress increased P5CS activity.
- Intervention effect Salt stress appeared not to affect OAT activity.
- Mechanism The glutamate pathway was implicated in proline accumulation during osmotic regulation.
- Intervention effect Salt stress decreased proline dehydrogenase activity.
- Mechanism Reduced proline catabolism may contribute to salt-induced proline accumulation.
- Intervention effect Salinity at or above 250 m m NaCl stopped reed growth.
- Intervention effect High salinity decreased proline accumulation and P5CS and OAT activities.
