Abstract/Contents:Drought is a meteorological term. It may be defined simply as an extended period of low rainfall. Water stress, however, refers to the plant directly and occurs to varying degrees during the entire life of the plant. Drought affects the morphology of plants - that is, the way in which plants grow. For instance, leaves that develop during drought possess thicker cuticles (a waxy layer on the leaf surface to prevent water loss) and fewer stomates. Drought also affects the relative proportion of photosynthates being distributed in leaves, roots, tillers and rhizones. Plants can be divided into three general categories concerning mechanisms of drought resistance: (1) drought escapers, (2) drought tolerance with high tissue water potential, and (3) drought tolerance with low tissue water potential. Management techniques have centered around the need to conserve water. They include limiting the use of nitrogen prior to the onset of drought, tensiometer controlled irrigation, and the use of wetting agents to improve wetting uniformity of the soil. Long range success may depend primarily on the use of drought resistant species and cultivars.
