摘要：
The relationship between sap flux and stem CO2 efflux was assessed for three mango trees. We observed higher than expected CO2 effluxes at the place of measurement under intermediate sap flux velocities and lower fluxes under high sap flux velocity. This variation disappeared after removing the tree crown.
