However, studies on their effects on plants are still limited. Here, we conducted a seed germination experiment for 5 days and a hydroponics experiment for 14 days to study the effects of silicon dioxide NMs(nSiO2) and silicon carbide NMs(nSiC) (0,10, 50, 200 mg/L) on rice (Oryza sativa L.). Bulk SiO2 (bSiO2) and sodium silicate (Na2SiO3) were used as controls. The results showed that nSiO2 and nSiC increased the shoot length (11-37%, 6-25%) and root length (17-87%, 59-207%) of germinating seeds, respectively, compared with the control. Similarly, inter-root exposure to nSiO2, bSiO2, and nSiC improved the activity of aboveground catalase (10-55%, 31-34%, and 13-51%) and increased the content of trace elements magnesium, copper, and zinc, thus promoting the photosynthesis of rice. However, Na2SiO3 at a concentration of 200 mg/L reduced the aboveground and root biomass of rice by 27-51% and 4-17%, respectively. This may be because excess silicon not only inhibited the activity of root antioxidant enzymes but also disrupted the balance of mineral elements. This finding provides a new basis for the effect of silica-based NMs promotion on seed germination and rice growth."],"journal":["Nanomaterials (Basel, Switzerland)"],"pagination":["4160"],"full_dataset_link":["https://www.ebi.ac.uk/biostudies/studies/S-EPMC9740595"],"repository":["biostudies-literature"],"pubmed_title":["Effect of Silica-Based Nanomaterials on Seed Germination and Seedling Growth of Rice (Oryza sativa L.)."],"pmcid":["PMC9740595"],"pubmed_authors":["Jiang Y","Yang J","Li Y","Wang Q","Zhou P","Rui Y","Zhu G","Sun Y","Li M","Zhang P","Lynch I"],"additional_accession":[]},"is_claimable":false,"name":"Effect of Silica-Based Nanomaterials on Seed Germination and Seedling Growth of Rice (Oryza sativa L.).","description":"The application of nanomaterials (NMs) in agriculture has become a global concern in recent years.
