Influence of Nanoparticles on Seed Germination and Seedling Growth of Vigna radiata L

We describe a simple and cost effective method for screening the effects, of stem extract along with biogenic nanoparticles synthesized from Cissus quadrangularis stem extract, on Vigna radiata seed germination and root length. At higher concentrations (200 μl to 300 μl) of stem extract (1 2.5 g ml ) germination was completely inhibited. The inhibition was dose dependent. Synthesized nanoparticles were characterized by UV-visible spectroscopy, XRD and FTIR analyses. The average size of BNPs was 15.9 nm. FTIR analysis revealed resultant groups as aldehyde, ketones, lactones, alkanes, amines, etc. The BNPs (10 mg ml and 15 mg ml at 200 μl to 300 μl) completely inhibited seed
