Other claims from this paper (12)
- Intervention effect Anther morphology worsened as heat stress increased from mild to extreme.
- Intervention effect Mild heat significantly decreased pollen viability relative to control.
- Intervention effect Mild heat significantly decreased grains per primary spike relative to control.
- Observation Sunstar performed well under mild heat.
- Observation Two CIMMYT breeding lines performed well under mild heat.
- Association Pollen viability and grain number per spike were positively correlated under heat.
- Intervention effect Extreme heat induced new tillers after heat stress.
- Association New tillers significantly contributed to final yield.
- Intervention effect Heat initially inhibited flag leaf photosystem II maximum quantum efficiency.
- Observation Flag leaf Fv/Fm recovered fully within days after heat.
- Association Heat stress was associated with earlier or faster leaf senescence by SPAD model fitting.
- Recommendation The authors propose heat-tolerant genotypes for mechanism studies and breeding.
