Other claims from this paper (8)
- Association Model photosynthesis and maintenance respiration rose with foliar nitrogen concentration.
- Association Optimal NPP increased nearly linearly at low to moderate nitrogen availability and saturated at high availability.
- Association At very low or high nitrogen availability, predicted foliar nitrogen concentration was steady.
- Association At intermediate availability, predicted foliar nitrogen concentration increased with nitrogen availability.
- Association Predicted carbon allocation to fine roots decreased as nitrogen availability increased.
- Association Predicted carbon allocation to wood increased as nitrogen availability increased.
- Association Predicted carbon allocation to foliage remained stable as nitrogen availability increased.
- Method / resource Predicted biomass density and foliage nitrogen relationships reasonably agreed with Finnish conifer stand data.
