Abstract
Nanotechnology is an enabling technology that allows us to develop materials with improved or totally new properties. Nanotechnology has the ability to completely transform the way seeds germinate by providing improved development, faster germination rates and greater resistance to environmental stressors. The present study focuses on synthesis and characterization of copper oxide and iron oxide nanoparticles using sol- gel method and chemical precipitation method, further these nanoparticles were subjected to characterization techniques like energy dispersive X-ray microanalysis (EDAX) and transmission electron microscopy (TEM) for evaluating its size, composition and surface morphology. Moreover, the influence of these nanoparticles were observed on physiological and biochemical parameters of Vigna radiata seeds. The results indicated that synthesized nanoparticles were copper oxide and iron oxide and were of size 20-50 nm having squarish to spherical morphology for copper oxide nanoparticles and hexagonal to spherical morphology for iron oxide nanoparticles. The Vigna radiata seeds exhibited that iron oxide and copper oxide nanoparticles considerably improved physiological characteristics at lower concentrations, however they have phytotoxic effects at greater doses, which impede the growth of seedlings and decrease seed germination. The biochemical indices, such as proteins, phenols, and carbohydrates, were shown to be highest at lower concentrations and to decrease with increasing dosages of nanoparticles.
