Stomatal regulation of evaporation from well-watered plant canopies: a new synthesis

Abstract

New experimental evidence is presented to resolve a long-standing controversy relative to the existence or non-existence of evaporation control by stomata in situations where the water supply to plant roots is non-limiting. It is shown that both sides of the argument were correct in certain respects, but that the claim for significant stomatal control was the one most representative of reality in the broadest perspective.
