Other claims from this paper (18)
- Intervention effect Greater heat intensity and duration significantly reduced grain yield.
- Intervention effect Greater heat intensity and duration suppressed spikelet number per panicle.
- Intervention effect Greater heat intensity and duration suppressed seed-setting rate.
- Intervention effect Greater heat intensity and duration suppressed grain weight.
- Intervention effect Booting heat reduced panicle dry matter partitioning index.
- Intervention effect Booting heat increased stem dry matter partitioning index.
- Intervention effect Booting heat had no significant effect on photosynthetic rate.
- Intervention effect Heat increased stem nonstructural carbohydrate concentration.
- Intervention effect Heat decreased panicle nonstructural carbohydrate concentration.
- Intervention effect Heat decreased stem carbohydrate translocation efficiency.
- Intervention effect Heat decreased the contribution of stem carbohydrates to grain yield.
- Intervention effect Severe heat turned the stem into a carbohydrate sink during grain filling.
- Observation Heat-tolerant Wuyunjing 24 had higher NSC transport capacity than heat-sensitive Nanjing 41 under heat.
- Observation The heat degree-day threshold for NSC translocation termination was 9.82 °C day.
- Association Grain yield was negatively correlated with stem NSC concentration at maturity.
- Association Grain yield was negatively correlated with stem NSC accumulation at maturity.
- Association Yield reduction was tightly related to reduced NSC translocation.
- Recommendation Authors suggest selecting higher NSC transport capacity under heat to benefit rice yield formation.
