Optimal plant water economy

Buckley, Thomas N.; Sack, Lawren; Farquhar, Graham


It was shown over 40 years ago that plants maximize carbon gain for a given rate of water loss if stomatal conductance, gs, varies in response to external and internal conditions such that the marginal carbon revenue of water, ∂A/∂E, remains constant over time. This theory has long held promise for understanding the physiological ecology of water use and for informing models of plant-atmosphere interactions. Full realization of this potential hinges on three questions: (i) Are analytical...[Show more]
