Water stress

(1986) Water stress. Elders Weekly, 9 October 1986. p. 12 [Publication] [Special Collections]


Water stress caused by shortage of moisture is the main limiting factor to crop growth throughout the world. A device developed at Britain's National Vegetable Research Station (NVRS) enables continuous measurements of plant water stress to be made in the field. The method involves using a psychrometer to measure atmospheric humidity in a small chamber of air humidified by the tissues of the plant stem. Researchers have attached psychrometers to the plant leaf previously, but the waxy leaf cuticle often prevents rapid exchange of water vapour between the leaf's tissue and the chamber air. The aim of the technique is to produce a specially designed and constructed psychrometer acceptable to a commercial market to provide a better understanding of the influence of water stress on crop yield.
