Other claims from this paper (8)
- Association When spikelets per unit area were extremely small, no definite relation was found between the percentage of ripened grains of rice and any spikelet component.
- Association The percentage of ripened grains tended to decrease as spikelets per panicle increased.
- Association The percentage of ripened grains tended to decrease as secondary rachis-branches per panicle increased.
- Association The percentage of ripened grains seemed to increase as panicles per unit area increased.
- Association When spikelets per unit area were extremely large, the percentage of ripened grains was positively correlated with panicles per unit area.
- Association When spikelets per unit area were extremely large, the percentage of ripened grains was negatively correlated with spikelets per panicle.
- Association When spikelets per unit area were extremely large, the percentage of ripened grains was negatively correlated with secondary rachis-branches.
- Mechanism The decrease of ripened-grain percentage with more spikelets per panicle is explained by lower carbohydrate storage in sheaths and culms before heading and lower photosynthetic products after heading.
