Background: Terminalia arjuna has many biological applications and their metal nanoparticles have no hazardous
effect on the environment. We have demonstrated that Terminalia arjuna bark mediated metal nanoparticles can be used to
enhance the germination of seeds.
Methods: To evaluate the effect on germination we treated Vigna unguiculata (black eyed peas) seeds with copper, silver and
gold nanoparticles synthesized by Terminalia arjuna bark. The synthesized metal nanoparticles were characterized by UVspectroscopy and size was confirmed by diffraction light scattering technique.
Results: After incubation of 48 hours, the effects were observed. It was observed that Vigna unguiculata (black eyed peas) seed
showed 30% germination in silver nanoparticles solution and 70% in copper nanoparticles, 0% was observed in gold nanoparticles.
Conclusions: The results obtained in the study showed the relevance of nanobiotechnology in agriculture to boost the production of crops.
