Interaction Between Plant Water Relations and Mineral Nutrition

Description

The interaction between plants and water, including hydration of plant cells and water transport within a plant is termed as plant water relation. Water potential is a term used to define the amount of water in the soil, plant and atmosphere. Evaporation of water from the leaves is mainly controlled by stomata and is unbalanced by the flow of water from the soil through the plants to the leaves, causing the plants to wilt. The most abundant constituent of all physiology active plant cell is water. It acts as a dissolution medium for substances. Plants consume a large amount of water on a daily basis, and a significant amount is lost through transpiration. This concept is plant and water useful in emphasizing the necessity of considering of all aspects of water relations in studying the water balance of plants. This concept leads to treatment of water movement in the system as analogous to the flow of electricity in a conducting system.
