【 摘 要 】

The extensive use of nanoparticles in all sectors including agriculture has led to concern about their long-term exposure effects to our ecosystem. In this research work we investigated the effect of synthesized ZnO nanoparticles (ZnO NPs) on TRITICUM AESTIVUM. ZnO NPs were synthesized by chemical method and further characterized by X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). Wheat was grown in soil by applying two concentrations (10 and 20 ppm) of ZnO NPs and Bulk ZnO through seed priming method. Growth, Yield, Total Phenolic Contents (TPC) and DPPH radical scavenging activity was monitored. Atomic absorption Spectroscopy (AAS) was used to determine concentration and uptake of elements in roots, shoots and grains. XRD and SEM results confirmed the formation of pure hexagonal wurtzite structure ZnO NPs. There was increase in growth and yield parameters by ZnO NPs treatments. ZnO NPs 10 ppm treatment significantly increased plant height, biomass, number of spikelets per spike, spike length, number of grains per spike compared to control and ZnO bulk treatments. ZnO NPs treatment at 10 ppm increased TPC by 60.37% compared to control group. The AAS results indicated increased Zinc content in roots by 88.89% and 112.59% in ZnO NPs 10 ppm and 20 ppm group respectively compared to Control. The Iron concentration in ZnO NPs at 10 ppm treated group grains increased by 113 % indicating improved nutritional quality of plant. It can be concluded that ZnO NPs application in minor concentration exhibits stimulatory effect on overall plant growth and grain nutrition.
