Other claims from this paper (19)
- Observation Endosperm cells moved toward the embryo-sac wall three days after flowering.
- Observation Endosperm cells divided rapidly four days after flowering.
- Observation Initial endosperm cells underwent further division five days after flowering.
- Observation Cell division continued until endosperm filled the embryo sac.
- Observation Endosperm cells began forming the aleurone layer six days after flowering.
- Observation The center line appeared clearly seven days after flowering.
- Observation Starchy cells around the center line were spindle-shaped and aligned with the kernel long axis.
- Observation Kernel length was nearing completion in this spindle-shaped stage.
- Observation Starchy endosperm cells then grew dorsoventrally and became rectangular.
- Observation Kernel dorsoventral diameter neared completion about ten days after flowering.
- Observation Starchy endosperm near the aleurone layer continued growing until about fifteen days after flowering.
- Observation Kernel lateral diameter neared completion about fifteen days after flowering.
- Observation Translucency began at the center line and spread outward.
- Observation Translucency progressed more slowly in the ventral than dorsal kernel.
- Association Ventral diameter correlated highly with dorsoventral diameter.
- Association White-belly frequently occurred in kernels with large ventral parts.
- Mechanism Insufficient nutrient movement was proposed to explain white-belly in large ventral parts.
- Association White-belly sometimes appeared even in kernels with a small ventral part, associated with poor nutrient accumulation.
- Observation Opaque starchy endosperm in milk-white grain developed poorly and accumulated insufficient nutrients.
