Abstract
Inhibition of leaf growth is usually the first whole plant response to soil water deficits (Hsaio, 1973; Chazen and Neumann, 1994). In the longer term, such inhibition will result in reduction in the leaf area available for photosynthesis and possible yield reductions. However, the chain of events by which soil water deficits in the root zones of plants are initially signaled to the leaves and then converted into a sustained inhibition of leaf growth, are still far from clear. In principle, the process could involve transmission of hydraulic, chemical or electrical signals from the stressed roots to the leaves.
