Wheat is major food crop of world but unfortunately its production is decreasing day by day due to over-population therefore it is need of hour to execute modern technologies like nanotechnology to perk up the yield of important food crop. The green synthesis and application of metallic nanoparticles has become a significantly important branch of nanotechnology. In present study, we report the green synthesis of silver nanoparticles using leaf extract of Moringa oliefera as reducing agent and tested their effects on seed germination as well as seedling growth. The exposure of Silver to leaf extract resulted in rapid reduction of Silver ions leading to the formation of Silver NPs in the solution. Biologically synthesized Ag NPs were applied to evaluate the effect on seed germination and seedling growth of Triticum aestivum L. an economically important food crop. Seeds were treated with different concentrations of Ag NPs (25ppm, 50ppm, 75ppm and 100ppm) and tested against control. Application of all concentrations of Silver nanoparticles promoted seed germination and seedling growth in wheat as compared to control. However significant results were observed at 100ppm AgNPs as compared to control. Also, a significant increase in root fresh weight, root dry weight, root length, and root elongation was recorded at 100ppm concentration of Ag NPs as compared to the control.. The results of this experiment revealed that the application of Ag NPs enhanced the germination in wheat. So this study is quite helpful in exploring the potential of green synthesized silver nanoparticles to boost up the germination and seedling growth of wheat.
