摘要

This study presents a sustainable approach to synthesizing gold nanoparticles (AuNPs) using Piper betle metabolites and investigates their potential to enhance growth and productivity in Vigna mungo (black gram). Betel-mediated AuNPs (B-AuNPs) were characterized by several biophysical techniques such as Fourier Transform Infrared (FTIR) analysis, which confirmed the roles of phenolic and flavonoid compounds in reducing and stabilizing AuNPs. Seed priming with B-AuNPs at optimized concentrations (100 µM) significantly boosted germination, morphological traits, crop yield, and antioxidant activity, showcasing a notable reduction in reactive oxygen species (ROS) and oxidative stress markers. The concentration-dependent response expressed the manifestation of cytotoxic effects. Thus, B-AuNPs promoted plant growth, seed yield and resilience of V. mungo. The findings advocate sustainable nanotechnology applications in agriculture and setting a foundation for eco-friendly yield enhancement strategies in global food systems.
