Other claims from this paper (9)
- Association PAN flux related linearly to ambient PAN mixing ratio in all species.
- Observation Measured PAN flux varied from 11 to 24 pmol m −2 s −1 among species.
- Observation Measured PAN flux was 12–48% of flux predicted from modeled stomatal conductance.
- Mechanism The flux comparison suggests mesophyll resistance to PAN uptake.
- Intervention effect Brief PAN exposure did not affect photosynthesis, transpiration or water-vapor conductance.
- Intervention effect Increasing stomatal resistance caused PAN uptake to drop.
- Intervention effect Varying leaf nitrogen did not appear to influence PAN uptake.
- Intervention effect Varying total leaf ascorbate did not appear to influence PAN uptake.
- Method / resource Authors infer PAN flux could be estimated with established stomatal conductance algorithms.
