In present study, Zinc Oxide nanoparticles (ZnO NPs) were synthesized from leaf extract of Catharanthus roseus by green synthesis method. The synthesized nanoparticles were characterized by UV-visible spectrophotometry and Dynamic light spectroscopy (DLS) that showed the synthesis of nanoparticles of average size 385 nm. | Influence of green synthesized zinc oxide nanoparticles on seed germination and seedling growth in wheat Triticum aestivum
