Stomatal behaviour of Red Delicious apple leaves as influenced by different moisture levels

Abstract

Water in plants and animals contributes as much to the essential properties of life as do fats, proteins, carbohydrates and minerals. It is the principal medium in which all metabolic processes occur in plants. It not only serves as a carrier of ions to and from cells, but also participates in all the processes of plant growth and development (Westwood, 4). The process of transpiration in plants and the opening and closing of stomata in the leaves is controlled by soil moisture. Success in commercial fruit culture largely depends upon availability of sufficient moisture, particularly during critical periods of tree growth and fruit development. However, because of the positive influence of irrigation on tree growth, fruit yield and quality of apple fruit, the development and adoption of an efficient irrigation regime is of prime importance which is still lacking in Kashmir region.
