Interaction of Carbohydrate Coated Cerium-Oxide Nanoparticles with Wheat and Pea: Stress Induction Potential and Effect on Development.

ABSTRACT: : Reports about the influence of cerium-oxide nanoparticles (nCeO₂) on plants are contradictory due to their positive and negative effects on plants. Surface modification may affect the interaction of nCeO₂ with the environment, and hence its availability to plants. In this study, the uncoated and glucose-, levan-, and pullulan-coated nCeO₂ were synthesized and characterized. The aim was to determine whether nontoxic carbohydrates alter the effect of nCeO₂ on the seed germination, plant growth, and metabolism of wheat and pea. We applied 200 mgL^-1 of nCeO₂ on plants during germination (Ger treatment) or three week-growth (Gro treatment) in hydroponics. The plant response to nCeO₂ was studied by measuring ch
