INFLUENCE OF ZINC OXIDE NANOPARTICLES ON GROWTH OF SESAMUM INDICUM L. IN ZINC DEFICIENT SOIL

Objective: A comparative examine of L. aculeate mediated ZnO (BZnO) and synthesized chemical ZnO (CZnO) nanoparticles became done which will decide the impact of seed germination on Sesamum indicum (CO-1). Methods: Zinc oxide nanoparticles had been synthesized by the biological and chemical methods. Synthesized nanoparticles have been confirmed with Ultra Violet–visible spectroscopy (UV-Vis), Fourier transform infrared spectrometer (FT-IR), Energy dispersive X-ray spectrometer (EDX), X-ray diffractometer (XRD), Field Emission Scanning Electron Microscopy (FESEM) and High-Resolution Transmission Electron Microscopy (HRTEM). Different concentration of synthesized zinc oxide nanoparticles (0.1, 0.25, 0.5, 1 and 2 g/l) solution were prepared and applied to Sesamum indicum by soaking approach. The impact of ZnO nanoparticles treated plants were studied by using the standard procedure on plant growth attributes (shoot and root length, dry and fresh weight of shoot and root), photosynthesis pigment (chlorophyll a, chlorophyll b and total chlorophyll) and biochemical analysis (protein, carbohydrate and reducing sugar). Results: The characterization analysis revealed that BZnO & CZnO NPs were spherical in shape with a mean particle size of 12±3 nm and 18±2 nm. The maximum observation of growth attributes was recorded in 0.5 g/l concentration of biologically synthesized ZnO nanoparticles which was compared to chemically synthesized ZnO nanoparticles. Conclusion: Results of this experiment revealed that Lantana aculeate mediated zinc oxide nanoparticles are an enhanced useful resource of Sesamum indicum. It is able to use as nano fertilizer in agriculture development. Keywords: Plant growth attributes, Sesamum indicum, Seed germination, Zinc oxide nanoparticles
