Other claims from this paper (7)
- Intervention effect Field nitrogen availability reduced rice sunlit leaf area index.
- Intervention effect Low PAR gave rice higher shoot nitrogen concentration than higher PAR.
- Association Photosynthetic rate correlated strongly with leaf nitrogen per area.
- Intervention effect Without nitrogen, rice dry matter yield did not differ between 150 and 400 μE m −2 s −1.
- Association Across nitrogen levels, rice dry matter increased with light intensity.
- Intervention effect Reduced light did not cause a proportionate decrease in rice growth.
- Mechanism The authors suggest increased shoot nitrogen is a shade-adaptation mechanism.
