Abstract :The green synthesis of silver nanoparticles (AgNPs) is a promising alternative to nanotechnology due to its stable, non-toxic, and eco-friendly approach. One such novel approach is the use of medicinal plants for the synthesis of AgNPs. In this study, the medicinal Himalayan fern Thelypteris erubescens was used for the green synthesis of AgNPs, and its effects on seed germination of maize and antimicrobial properties were investigated. AgNPs from Thelypteris erubescens were synthesized by adding silver nitrate to plant extract and the synthesis of AgNPs was validated and characterized through ultraviolet spectroscopy (UV), scanning electron microscopy (SEM), and X-ray diffraction (XRD). AgNPs of varying concentrations displayed antibacterial and antifungal activity through agar well diffusion. Thelypteris erubescens nanoparticle synthesis demonstrated superior antibacterial efficiency compared to methanol and aqueous extracts. The application of AgNPs derived from Thelypteris erubescens stems significantly enhanced maize seed germination, surpassing traditional methods. Silver nanoparticles have been proven to enhance plant growth and seed germination ability at controlled envioroment. This eco-friendly and cost-effective approach maximizes the effects of growth-regulating hormones and exploits plants' potential against microbial strains.
