- Intervention effect Square-stage drought significantly reduced cotton SPAD at flower-boll stage.
- Intervention effect Square-stage drought significantly reduced cotton Fv/Fm at flower-boll stage.
- Method / resource Cluster analysis separated cotton cultivars into five drought-response groups.
- Association Under drought, tolerant cultivars had a less pronounced root-shoot ratio increase.
- Association Under drought, tolerant cultivars yielded 24.25% more than sensitive cultivars.
- Association In the 50–60 cm soil layer, tolerant cultivar root length density was 141.78% higher than sensitive cultivars under drought.
- Observation Sensitive and tolerant cultivars had symmetric root distribution in the 0–30 cm soil layer.
- Observation At boll opening, root spatial distribution showed no significant differences amid substantial rainfall.
- Recommendation The authors conclude that optimizing lateral root angle, root-shoot ratio, and deeper root density reduces drought-related yield loss.
