Abstract
The synthesis of gold nanoparticles (AuNPs) using Zingiber officinale has been reported in the study, and the impact of the different concentrations (ppm) of gold nanoparticles is investigated. Five different concentrations (0, 10, 25, 50 and 100 ppm) of gold nanoparticles were applied to examine physiological (including seeds germination, plant height, leaf number and biomass production) and biochemical parameters (including total soluble sugars, total soluble phenols, total chlorophyll, carotenoids, total soluble amino acids and protein contents) of the seedlings of Lens culinaris as a model of Legumes crop. GNPs were synthesized and characterized through Uv-visible spectra, transmission electron microscopy, XRD and FTIR. Generally, all growth and biochemical parameters were increased as a result of treatment with gold nanoparticles by using low concentrations only at 5ppm and 10ppm, while at high concentrations the effect is reversed.
