Abstract

The aim of this study was to investigate the phytotoxicity of Fe2O3 nanocubes, Fe2O3 short nanorods, Fe2O3 long nanorods, TiO2 NPs; and MWCNTs to rice (Oryza sativa L.) seedlings during germination, including rice germination ratio, root length, shoot length and fresh weight. Our investigation found that all nanoparticles inhibited the germination of rice seeds. Fe2O3 nanocubes, Fe2O3 short nanorods, Fe2O3 long nanorods and TiO2 NPs all significantly promoted the root length, and stimulated shoots growth at most concentrations, but had no obvious effect on fresh weight.. Our study showed a comprehensive understanding of nanoparticles toxicity during plants germination. To our best knowledge, it was the first time to investigate the influence of Fe2O3 nanomaterials morphologies on plants germination.
