Abstract Cerium oxide nanoparticles (CeO2NPs) are likely to have dramatic
impacts on plant performances, yet the effects of CeO2NPs on seed germination
and seedling growth have not been fully explored. In this study, the seed germination and seedling growth of subshrub species Vitex negundo under different
concentrations of CeO2NPs (low-1 mg/L, medium-100 mg/L, high-500 mg/L)
have been discussed. Results showed that: (1) The seed germination rate reduces
by 11.25% and 2.5% under the low and medium concentrations of CeO2NPs,
respectively, but increased by 7.08% under the high concentration; (2) CeO2NPs
had significant effects on the growth traits (root length, shoot… More >
