Abstract :
    Fennel, a medicinal plant with numerous health benefits, is susceptible to heavy metal contamination, such as cadmium. This study investigated the mitigating effects of seaweed extract and melatonin seed pre-treatments on cadmium toxicity in fennel plants. Results indicated that these pre-treatments significantly enhanced root and shoot growth, chlorophyll and carotenoid content, while reducing proline accumulation. These findings suggest that seaweed extract and melatonin can be employed as biostimulants to enhance plant tolerance to cadmium stress. This research contributes to the development of sustainable agricultural practices aimed at mitigating the adverse effects of heavy metal contamination.
