Abstract:
This research project aims to analyze the effects of air pollution on plant physiology and growth. Air pollution, particularly the presence of pollutants such as ozone, nitrogen dioxide, and particulate matter, poses a significant threat to plant health and ecosystem functioning. This study will investigate the physiological responses of plants to air pollution, including changes in photosynthesis, stomatal conductance, antioxidant defense mechanisms, and growth parameters. The research will involve field measurements, controlled experiments, and data analysis to understand the impacts of air pollution on plant physiology and growth. The findings will contribute to our understanding of the ecological consequences of air pollution and may have implications for air quality management and plant conservation.
