Other claims from this paper (10)
- Intervention effect High temperature reduced kernel thickness most when started 12 days after heading.
- Intervention effect Kernel length and width were most sensitive to high temperature earlier in development.
- Intervention effect Abortive and opaque kernels were most evident with heat starting four days after heading and most numerous at the highest temperature.
- Mechanism Temperatures above 27/22¦C appear to interfere with early endosperm cell division and development.
- Association Chalky endosperm took several forms depending on temperature and treatment timing.
- Intervention effect White-core kernels occurred only at 27/22¦C.
- Intervention effect White-back kernels were most numerous at 36/31¦C and with heat beginning 16 days after heading.
- Intervention effect Milky-white kernels occurred in all treatments except 24/19¦C, peaked at 36/31¦C, and were most evident with heat starting 12 days after heading.
- Observation Endosperm cellular morphology differed among damage types.
- Mechanism Chalkiness was associated with numerous air spaces among loosely packed starch granules and altered light refraction.
