Other claims from this paper (16)
- Observation Heat tents raised daytime temperature by 1.2–2.0 °C across two years.
- Observation Nighttime temperature was similar inside and outside heat tents.
- Intervention effect Cooler water lowered soil temperature by 0.2–1.4 °C, especially under control conditions.
- Intervention effect Heat stress reduced grain yield by 33% to 43%.
- Intervention effect Heat stress reduced panicles per square metre by 9% to 10%.
- Intervention effect Heat stress reduced spikelets per square metre by 15% to 22%.
- Intervention effect Heat stress reduced grain filling by 13% to 26%.
- Intervention effect Heat stress reduced 1000-grain weight by 3% to 5%.
- Intervention effect Heat stress increased chalkiness and protein content.
- Intervention effect Heat stress decreased grain length and amylose content.
- Association Grain yield was negatively associated with canopy air temperature and soil temperature.
- Association Chalkiness was positively associated with air and soil temperatures.
- Intervention effect Cooler groundwater reduced heat-related grain yield loss by 8.8% in LYPJ.
- Intervention effect The same mitigation was absent in IIY602.
- Intervention effect Cooler groundwater did not significantly mitigate rice yield loss or improve grain quality under field conditions.
- Recommendation The authors recommend exploring integrated management and genetic options at canopy level.
