Study of water concentration on Pea Plant !

On a global basis, water is a paramount factor in determining the distribution of species, and the responses and adaptations of a species to water stress are critical for its success in any environmental niche. Water stress is the major environmental stresses that affect agricultural production worldwide, especially in arid and semi-arid regions. This research investigated the effect of water stress on pea (pisum sativum) plant.The effect of water stress on growth parameters was investigated including; plant height, leaf area, dry weights of roots, shoots and whole plant. Water stress adversely impacts many aspects of the physiology of plants, especially photosynthetic capacity. If the stress is prolonged, plant growth, and productivity are severely diminished. Plants have evolved complex physiological and biochemical adaptations to adjust and adapt to a variety of environmental stresses. The molecular and physiological mechanisms associated with water-stress tolerance and water-use efficiency have been extensively studied. What does water do for a plant? There are three potential situations with water: too much, too little and, of course, just enough.
