Linked control in sunflowers of transpiration, leaf water status and chemical messages from in the roots.
Abstract
The nature of water transport within the plant, stomatal function and the role of abscisic acid in stomatal movement are reviewed. The relationship between water status and stomatal control is clarified as a result of trials with field-grown sunflowers and detached leaves and the possible nature of controls for avoidance of dehydration at the whole-plant level are discussed. 10 ref.
