The Effects of Water Stress on the Enviroment
Water is required for all life processes and often limits plant development. For example, when the grass does not receive sufficient water, its growth slows and ceases long before it starts to look sick and turn brown. Water is required to maintain cell turgidity and to provide a substrate and medium for chemical reactions and for the transport of mineral ions in the plant; also when transpired from the leaves, water is of some value in cooling and maintaining a plant temperature suitable for metabolic reactions. Plants growing in natural environments are often prevented from expressing their full genetic potential for reproduction and are considered stressed. The best way of assessing this potential is by determining plant productivity under conditions that are nonlimiting. One method is to identify the highest yields attained by crops. Corn, for example, yields 4600 kilograms per hectare on average but also has had a record yield of 19,300 kilograms per hectare (Erdei 1998). The effects of water stress on plant growth puts a major limitation on grain yields throughout the world. Silk growth and leaf growth is inhibited under water stress. The major economic consequence of insufficient water on maize and cor
