Abstract: The comparative morphophysiological study between Pearl millet (Pennisetum glaucum) and Finger millet (Eleusine coracana) under metal stress in addition with indole acetic acid (IAA) involves analyzing various plant characteristics affected by these conditions. This study aims to explain the differential responses of these two millet species to metal stress of Cadmium and the effects of IAA. Morphophysiological parameters including plant height, root length, chlorophyll content, metal accumulation, and stress-induced anatomical changes are assessed. The impact of metal stress on growth and development is evaluated, highlighting differences in the adaptive mechanisms exhibited by pearl and finger millet. Additionally, the role of IAA in mitigating
metal-induced stress by potentially modulating plant growth regulators, enzymatic activities, and metal uptake mechanisms is investigated. The comparative analysis throws light on the species-specific responses of pearl and finger millet to metal stress, revealing potential strategies for enhancing stress tolerance in these crops. Chlorophyll content was evaluated by the help of spectrophotometer and dry weight and fresh weight were taken. Understanding these morphophysiological differences and the influence of IAA provides insights into improving crop productivity under metal-contaminated environments, contributing to sustainable agriculture and food security.
Keywords: Pearl millet, finger millet, indole acetic acid, cadmium, metal stress.
