Abstract

BIOGENIC SILVER NANOPARTICLES SYNTHESIZED WITH MEDIATION BY EUPHORBIA HIRTA ENHANCE SEED GERMINATION AND ELIMINATE MICROBIAL CONTAMINATION

ABSTRACT

Current investigation demonstrates the potentials of silver nanoparticles synthesized mediated by Euphorbia hirta in enhancing the growth of Vigna unguiculata, Vigna radiata and Cicer arietinum seedlings. The study was carried out by pore optimum concentrations of nanoparticles in suspension on hydroponically grown test units and examining the effect on the seed germination and seedling growth. Based on biomass assay, it was found that the seedlings displayed significant growth over control, demonstrating a positive effect of the nanoparticles treatment. The best performance was observed for silver nanoparticles in seed germination. The nanoparticles were characterized by UV-visible spectroscopy, Fourier transform infrared spectroscopy, Field emission scanning electron microscopy and Particle size analyzer, Moreover, presence of the AgNPs in the germination medium prevented contamination usually caused by seed-borne microbes.

Keywords: Euphorbia hirta, silver nanoparticles, seed germination.
