Drought Stress: Responses and Mechanism in Plants

The function of water for plants is crucial, including playing the roles in metabolic reactions. aims this article are to give information on effects drought stress plant morphology, physiology, and biochemistry, as well mitigation methods management production. Plants manage using a mechanism, namely escape, avoidance tolerance. Drought escape ability accelerate flowering or life cycle, reduce loss increase absorption through morphological changes root system, tolerance adaptation by physiological biochemical processes. Physiological that occur include closing stomata decreased photosynthesis. responses synthesis solute compounds form osmotic adjustment cell called from cell. indicators increased concentrations abscisic acid (ABA), proline, sugar (trehalose). ABA acts signal stimulate stomatal closure transpiration rate. Proline an indicator adapting stress, role cells retain Trehalose compatible acting osmoprotectant, it can maintain integrity membranes (water replacement) hydrogen bonds entrapment). under conditions adapt making morphological, physiological, adjustment. These need be managed so appropriate strategies technologies needed measures.
