Synopsis Plant growth is controlled directly by plant water stress and only indirectly by soil water stress. Plant water stress depends on the relative rates of water absorption and water loss rather than on soil water supply alone, hence it is not safe to assume that a given degree of soil water stress always will be accompanied by an equivalent degree of plant water stress. Plant water stress should be measured directly in research on the effects of water supply on plant growth and plant processes if the results are to be interpreted correctly.
