Claim · model-written summary
The model attributed higher overcast assimilation and conductance to lower T1 and D and more even canopy irradiance.
- Outcome

Other claims from this paper (7)
- Observation Whole-tree gas exchange responses resembled individual leaf responses in Macadamia integrifolia.
- Observation Whole-tree gas exchange responses resembled individual leaf responses in Litchi chinensis.
- Observation Under overcast skies, Macadamia integrifolia had higher stomatal conductance and CO2 assimilation than under clear skies at given irradiance.
- Observation Under overcast skies, Litchi chinensis had higher stomatal conductance and CO2 assimilation than under clear skies at given irradiance.
- Observation The overcast-sky difference persisted after accounting for sun angle.
- Method / resource A light interception and leaf response model described isolated-tree gas exchange well.
- Mechanism The model suggested near-optimal partitioning of photosynthetic machinery across the canopy.
