Other claims from this paper (11)
- Intervention effect Drought hardening inhibited increases in relative electric conductivity and malondialdehyde content.
- Intervention effect Drought-hardened seedlings had enhanced root vigor under drought.
- Intervention effect Drought-hardened seedlings had increased antioxidant enzyme activity.
- Intervention effect Drought-hardened seedlings had higher abscisic acid, proline and soluble sugars under drought.
- Intervention effect Drought-hardened seedlings had higher polyamine levels under drought.
- Intervention effect Stomatal density increased significantly with drought hardening.
- Intervention effect Leaf area, stomatal size and stomatal aperture decreased with drought hardening.
- Observation The changes reduced leaf transpiration rate.
- Observation The changes improved water utilization efficiency.
- Mechanism Leaf microstructure changes had a positive effect on drought resistance.
- Mechanism Authors attribute enhanced resistance physiology to increased hormones, osmotic substances and antioxidant enzyme activity.
