Plant Adaptations to Drought Stress: Morphological, Physiological and Biochemical Responses
Abstract: Drought stress is one of the major abiotic constraints affecting plant growth, development, productivity and survival. Water deficiency disrupts cellular water relations and subsequently influences plant morphology, physiology, metabolism and molecular regulation. Plants respond to drought through a combination of adaptive mechanisms rather than through a single tolerance trait. Morphological responses include modification of root architecture, reduction in leaf area, leaf rolling, changes in shoot growth and altered biomass allocation. …
