In order to study the effect of chitosan and SiO2 nanoparticles (NPs) on germination and growth of wheat seeds, a factorial experiment (2×4) was performed based on a completely randomized design in four replications. Th e experimental factors included the above NPs types, with concentrations at 0, 30, 60 and 90 ppm. Seeds were separately soaked for six hours, along with the concentrations of both NPs. Th e types and concentration of NPs did not show any significant effect on parameters such as Germination Percentage (GP), germination rate (GR), Mean Germination Time (MGT), Mean Daily Germination (MDG), Pick Value (PV), Germination Value (GV) and coleoptile fresh weight. Yet, increase in the concentration of NPs, had significant effects on shoot, seedling, coleoptile, root length, fresh and dry weight, as well as vigor index of seedlings. Also, in most measured traits, effect of chitosan NPs was better than SiO2 NPs. Finally, direct exposure to the above mentioned NPs have produced both positive and negative effects on wheat growth.
