Abstract
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. To evaluate the effect of ZnO NPs on seed germination, various concentrations of nanoparticles (20, 50 and 100 ppm) were used for the treatment of wheat seed but there was not observed any significant effect on germination percentage, speed of germination and mean germination time. However, root length, shoot length, seedling length, root dry weight, shoot dry weight, seedling dry weight and seed vigour index (I and II) showed a significant increase at 50 ppm. Further, by increasing the concentration of ZnO NPs (at 100 ppm), a decrease was observed in all parameters which stipulated the toxicity of synthesized nanoparticles at higher concentration. Thus, the results of this study demonstrated that Catharanthus roseus leaf can be used as a good source for green synthesis of ZnO NPs and the treatment of ZnO NPs influenced the seedling growth and Seed vigour index significantly.
