Abstract:
The objective of the present study were to synthesize copper oxide and magnesium oxide nanoparticles, using aqueous fruit extracts of Cucumis sativus as a reducing agent with copper nitrate and magnesium nitrate serving as a precursors. The synthesized nanoparticles were characterized using Uv-vis, FTIR, XRD, and SEM techniques. The UV-Vis spectral of CuO-NPs displayed an absorption peak at 228 nm while MgO-NPs showed a specific absorption at 266.7 nm which is in the range of 260-280 nm. X-ray diffraction analysis identified the CuONPs possess monoclinic structure while MgO-NPs possess highly crystalline structure. Fourier transform Infrared analysis identified some biomolecules and functional groups in the aqueous fruit extract of Cucumis sativus as responsible for the reducing copper nitrate and magnesium nitrate to CuO and MgO nanoparticles respectfully. After the characterization, the effect of CuO and MgO nanoparticles on germination of Arachis hypogaea seeds was investigated. The parameters such germination percentage, root length and shoot length were analyzed and the result compared. The result indicated that germination percentage in CuO-NPs treated seed of Arachis hypogaea decreases with increase in concentration of nanoparticles while in MgO-NPs treatment showed increase in germination percentage with increase in concentration. In root length, CuO-NPs decreases root length and MgO nanoparticles increases root length. Both CuONPs and MgO nanoparticles shoot length with increase in concentration of nanoparticles.
