Abstract

Plants need to be included to develop a comprehensive toxicity profile for nanoparticles (NPs). In this experiment, the effects of chitosan silicon dioxide (SiO2) NPs with concentrations 0 (control), 30, 60 and 90 ppm was assessed on barley seeds. For starting the experiment, the barley seeds were separately placed in petri dishes. Then, 5 mL of the both NPs concentration were added to them. Results showed that the treated seeds with different concentration of NPs showed significant effects on barley germination and growth parameters. Applications of both NPs in 90 ppm, especially SiO2 NPs, displayed adverse effects on the studied traits; whereas, using both NPs with 30 or 60 ppm had not significant effects on majority of the studied traits in barley plants. In general, the usage of these NPs in high concentration (90 ppm) could curb the undesired growth and germination of barley plants.
