Other claims from this paper (8)
- Association Light saturated photosynthesis correlated with leaf nitrogen.
- Association Vertical leaf nitrogen distribution was associated with absorbed light gradient.
- Observation At high nitrogen supply, leaf nitrogen profiles stayed constant during crop development.
- Observation At low nitrogen supply, leaf nitrogen profiles fluctuated between uniform and steep distributions.
- Association These profile changes were associated with reduced leaf area expansion.
- Association These profile changes were associated with increasing nitrogen remobilization from lower leaf layers.
- Observation Leaf nitrogen distribution relative to absorbed light was close to the theoretical photosynthesis optimum.
- Mechanism Model sensitivity analysis suggested plants maintain optimal vertical leaf nitrogen distribution by balancing photosynthetic capacity at high and low light.
