Ph.D. in Plant Physiology typically requires 3 - 5 years of study and research following a master's degree in a related field, such as biology, botany, or agricultural science. This program focuses on the physiological processes of plants, including growth, metabolism, and responses to environmental factors. Students engage in advanced coursework, laboratory experiments, and field studies to investigate plant functions and adaptations. Research may cover topics such as photosynthesis, water relations, nutrient uptake, and plant stress responses. Graduates often pursue careers in academia, research institutions, or the agricultural industry, contributing to advancements in crop production and environmental sustainability.
