Biosynthesis of MgO nanoparticles using mushroom extract: effect on peanut (Arachis hypogaea L.) seed germination.

Abstract：

:Current study describes the green, environmental friendly, and cost-effectiveness technique for the preparation of MgO nanoparticles (NPs) via white button mushroom aqueous extract. The synthesized MgO NPs were characterized using equipments such as X-ray diffraction, dynamic light scattering (DLS), scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), and thermal gravimetric analysis (TGA) for average crystalline size, particle size, morphology, elemental analysis, and weight loss of the materials, respectively. This study reports the application of gardened sizes of (20, 18.5, 18, 16.5, and 15 nm) biosynthesized MgO NPs on seed germination. The smaller size (15 nm) MgO NPs have been enhanced the seed germination and growth parameters as compared with remaining sizes of MgO NPs and control. The magnesium oxide NPs penetrates into peanut seeds and affecting on seed germination and growth rate mechanism. In addition, this germination found to be high in seeds than germination on selected soil plot MgO NPs (0.5 mg/L stable concentrations) compared to different size of MgO NPs and control. Physicochemical methods indicated that the MgO NPs are able to penetrate into the seed coat and support water uptake inside of seeds. Probably, this positive effect may cause for the uptake of MgO NPs by the plants, as indicated in the UV and SEM analyses. As the smaller size (15 nm) of MgO NPs particles stimulates the development of seedling and growth enhancement of peanut, it clearly indicates that the current study is helpful in growing of peanuts in large-scale agricultural production.
