- Intervention effect Top-dressing increased differentiated spikelets per panicle.
- Intervention effect Top-dressing decreased degenerated spikelet percentage.
- Intervention effect Top-dressing increased surviving spikelets per panicle.
- Intervention effect Shading increased degenerated spikelet percentage.
- Intervention effect Shading decreased surviving spikelets per panicle.
- Intervention effect Higher day and night temperature raised degenerated spikelet percentage.
- Observation Treatments mainly affected secondary-branch spikelets.
- Intervention effect Primary-branch spikelet numbers did not change appreciably.
- Association Surviving spikelet response depended on differentiated spikelet number.
- Association Higher shoot dry weight at heading was associated with less spikelet degeneration.
- Association A higher shoot dry weight to differentiated spikelets ratio was associated with less degeneration.
- Association Shoot dry weight and nitrogen absorption at heading affected surviving spikelets more than their respective survival ratios.
- Observation The overall results were similar in Akenohoshi and Yangdao 4.
- Association Akenohoshi degeneration responded more strongly to shoot dry weight and its ratio than Yangdao 4.
- Association Surviving spikelets responded to shoot dry weight and nitrogen absorption at heading in Akenohoshi.
- Observation Akenohoshi had a higher surviving spikelet to nitrogen ratio than Yangdao 4.
- Observation Akenohoshi had more surviving spikelets per panicle than Yangdao 4 at the same dry weight and nitrogen absorption.
