An improved theory for calculating leaf gas exchange more precisely accounting for small fluxes

Marquez, Diego; Stuart-Williams, Hilary; Farquhar, Graham


The widely used theory for gas exchange proposed by von Caemmerer and Farquhar (vCF) integrates molar fluxes, mole fraction gradients and ternary effects but does not account for cuticular fluxes, for separation of the leaf surface conditions or for ternary effects within the boundary layer. The magnitude of cuticular conductance to water (gcw) is a key factor for determining plant survival in drought but is difficult to measure and often neglected in routine gas exchange studies. The vCF...[Show more]
