Abstract

The present paper is focused on green synthesis of high purity sulfur nanoparticles (SNPs) and its effect on seed germination and seedling growth of cucumber (Cucumis sativus). Synthesized SNPs were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy equipped with energy-dispersive X-ray spectroscopy (SEM-EDS). The crystalline size of synthesized SNPs as calculated by Scherer equation was 40 nm. SEM analysis of the SNPs is in spherical shape and with a diameter size between 5-80 nm. In the present study, different concentrations of SNPs were used for the treatment of cucumber seeds to study the effect on bioavailability of seed germination and seedling growth of cucumber. The results of this experiment showed that an increase in concentrations of SNPs had significantly increased seed germination and seedling growth of cucumber.
