Impact of Environmental Stress on Plant Growth and Adaptation

Abstract

Environmental stress is a major factor influencing plant growth, development, and survival. Plants are continuously exposed to a range of abiotic stresses such as drought, salinity, extreme temperatures, and nutrient deficiency, as well as biotic stresses including pathogens and herbivores. the impact of environmental stress on plant growth and adaptation, focusing on the physiological, biochemical, and molecular responses that enable plants to cope with adverse conditions. how environmental stress affects key plant processes such as photosynthesis, respiration, water balance, and nutrient uptake, often leading to reduced growth and productivity. adaptive mechanisms including morphological changes, stress-responsive gene expression, antioxidant defense systems, and hormonal regulation. Advances in plant biology and biotechnology have improved understanding of stress tolerance and offer opportunities for developing stress-resilient crops. understanding plant responses to environmental stress is essential for improving agricultural sustainability and food security in the context of climate change.
