Abstract This study investigates the photosynthetic adaptations of C3 and C4 grasses under water stress conditions, aiming to enhance our understanding of their ecological significance and agricultural potential. Using a field-based comparative approach, we examined the physiological responses of C3 and C4 grasses to controlled water stress at the Grassland Reserve. Data collection included measurements of photosynthetic rates, stomatal conductance, leaf water potential, and leaf anatomical characteristics. Statistical analysis revealed that C4 grasses exhibited superior photosynthetic efficiency and water use efficiency compared to C3 grasses under both normal watering conditions and water stress. Additionally, C4 grasses exhibited anatomical adaptations conducive to water conservation, such as thinner leaves and higher stomatal density. These findings underscore the importance of the C4 pathway in enhancing carbon fixation efficiency and minimizing water loss during drought. The implications of this research extend to ecological conservation and agricultural sustainability, with potential applications in biodiversity conservation, land management, and crop breeding programs.
