Cerium Oxide Nanoparticles Impact Yield and Modify Nutritional Parameters in Wheat (Triticum aestivum L.) (original) (raw)

Journal of Agricultural and Food Chemistry

The implications of engineered nanomaterials on crop productivity and food quality are not yet well understood. The impacts of cerium oxide nanoparticles (nCeO2) on growth and yield attributes and nutritional composition in wheat (Triticum aestivum L.) were examined. Wheat was cultivated to grain production in soil amended with 0, 125, 250, and 500 mg nCeO2/kg (control, nCeO2-L, nCeO2-M, and nCeO2-H, respectively). At harvest, grains and tissues were analyzed for mineral, fatty acids, and amino acids contents. Results showed that, relative to the control, nCeO2-H improved plant growth, shoot biomass, and grain yield by 9.0, 12.7, and 36.6%, respectively. Ce accumulation in roots increased at increased nCeO2 concentration but did not change across treatments in leaves, hull and grains indicating a lack of Ce transport to the aboveground tissues. nCeO2 modified the S and Mn storage in grains. nCeO2-L modified the amino acids composition, and increased the linolenic acid by up to 6.17%...
