摘要

The growing world population needs increase in agricultural production through the implementation of new technologies. In recent years, the world has observed an exceptional boom in nanotechnology and little is known about manganese sulfide nanoparticles (MnS NPs) and plant interactions. The current study was aimed to assess the effect of MnS NPs on Eruca sativa and Linum usitatissimum through soil application. Physiochemical characterization by Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), Energy-Dispersive X-ray (EDX) Spectroscopy, X-ray Diffraction (XRD) and Dynamic Light Scattering (DLS) confirmed spherical shape, 8 nm MnS NPs with presence of different functional groups on the surface. The application MnS NPs in soil at 40 and 60 mg/kg improved root and shoot length, number of branches, fruits per plant, seeds per fruit, and oil content in E. sativa and L. usitatissimum, respectively. Atomic absorption spectroscopy showed accumulation of Mn in root > shoot > seeds of both plant species. In E. sativa, oil percentage in seeds increased up to 53.75% at 40 mg/kg NPs while in L. usitatissimum at 60 mg/kg soil NPs, oil increase was 51.34%. NPs activated enzymatic antioxidants like Superoxide Dismutase (SOD), and Peroxidase (POD) and non-enzymatic antioxidants (phenolics and flavonoids) in concentration dependent manner in both plants. The plants also showed higher 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, total antioxidant capacity (TAC), and total reducing power (TRP) to cope inadequate effect of NPs. The hierarchical cluster analysis (HCA) revealed that 40 and 60 mg/kg soil MnS NPs stimulate plant growth and productivity. It can be concluded that MnS NPs can be used as nano-fertilizer for better growth and yield of oilseed plants.
