Other claims from this paper (9)
- Intervention effect Cutting half the leaves (1/2L) minimized yield losses to 2.3–5.9% through photosynthetic compensation
- Intervention effect Cutting half the leaves at the full boll stage (FBS-1/2L) gave the smallest yield reduction (2.3–2.9%)
- Intervention effect Cutting half the bolls at the full boll stage (FBS-1/2B) reduced yields by 35.7–41.9%
- Observation Under FBS-1/2B the compensatory rate was only 8.1–14.3%
- Observation Compensation rates under IFS-1/2B and FABS-1/2B reached 26.7–32.3% and 18.7–23.8% of yield
- Mechanism Sink loss leads to yield collapse, the authors propose because reproductive development is irreversible
- Mechanism Source damage can be buffered by physiological compensation
- Mechanism Sink strength is the core regulator of yield in high-yield cotton fields
- Recommendation Optimizing sink quality through moderate boll thinning at IFS, water and fertilizer at FABS and sink organ protection at FBS is recommended
