Other claims from this paper (10)
- Intervention effect Changhan 58 had a significantly higher percentage variation of transpiration than Xinong 9871 at the heading stage under water stress.
- Observation Changhan 58 had lower stomatal density than the other cultivar under both water conditions.
- Observation Changhan 58 had higher stomatal area per unit organ area than the other cultivar under both water conditions.
- Intervention effect Water stress decreased stomatal density, stomatal area per unit organ area and stomatal width in wheat.
- Intervention effect Water stress increased stomatal length in wheat flag leaves and ear organs.
- Intervention effect Instantaneous water use efficiency increased slightly under water stress compared with well-watered plants.
- Intervention effect Integral water use efficiency improved significantly under water stress in both cultivars.
- Observation Changhan 58 had higher integral water use efficiency than Xinong 9871.
- Observation Integral water use efficiency of Changhan 58 increased by a greater amount than that of Xinong 9871.
- Mechanism Drought resistance of Changhan 58 is suggested to be regulated by stomatal characteristics through a decrease in transpiration rate that improves integral WUE and photosynthetic performance.
