Background: Terminalia arjuna has many biological applications including synthesis
of metal nanoparticles, which have no hazardous effect on the environment. We have demonstrated
that metal nanoparticles synthesized using Terminalia arjuna bark 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 UV-spectroscopy and their 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, whereas 0% germination was observed in gold nanoparticles.
Conclusion: The results obtained in the study show that nanobiotechnology can be applied in
agriculture to boost the production of crops.
