Other claims from this paper (11)
- Association Higher daily mean temperature from 16° to 28°C accelerated grain filling and maturation.
- Observation At 28°C, upper grains of IR20 took 13 days to reach maximum weight.
- Observation At 28°C, upper grains of Fujisaka 5 took 18 days to reach maximum weight.
- Observation The optimum daily mean temperature for maximum IR20 grain weight was 19° to 25°C.
- Observation The optimum daily mean temperature for maximum Fujisaka 5 grain weight was 16° to 22°C.
- Observation IR20 appeared better adapted to high ripening temperatures than Fujisaka 5.
- Association Temperatures outside the optimum range produced more chalky grains.
- Association Day and night temperatures both affected grain weight and quality.
- Method / resource Daily mean temperature was the most meaningful measure for describing temperature effects on grain filling.
- Intervention effect Low light intensity appeared to delay whole-panicle grain filling slightly.
- Intervention effect Low light intensity appeared to reduce the percentage of filled grains on lower branches.
