Other claims from this paper (10)
- Intervention effect Reduced supplemental irrigation inhibited maize growth.
- Intervention effect Leaf area index, photosynthetic and gas exchange measures, chlorophyll content and photochemical quenching decreased as irrigation decreased.
- Intervention effect Leaf water use efficiency increased with decreasing irrigation.
- Intervention effect Normal irrigation and moderate deficit did not differ significantly.
- Intervention effect Normal irrigation and severe deficit differed significantly.
- Intervention effect Initial fluorescence, maximum photochemical efficiency and nonphotochemical quenching changed insignificantly.
- Mechanism Reduced photosynthetic capacity and light energy transfer efficiency were identified as the main factors in yield loss.
- Association Cultivars with smaller changes were less affected by drought stress and had stronger drought resistance.
- Observation Zhongke11 and Zhengdan958 were ranked ahead of Xundan20 and Xundan22 for drought resistance.
- Recommendation Moderate supplementary irrigation was recommended for saving water and stabilizing production under seasonal drought.
