Abstract
The aims of our experiment were to evaluate the uptake and translocation of cerium and titanium oxide nanoparticles and to verify their effects on the growth cycle of barley ( Hordeum vulgare L.). Barley plants were grown to physiological maturity in soil enriched with either 0, 500 or 1000 mg·kg −1 cerium oxide nanoparticles ( n CeO 2 ) or titanium oxide nanoparticles ( n TiO 2 ) and their combination. The growth cycle of n CeO 2 and n TiO 2 treated plants was about 10 days longer than the controls. In n CeO 2 treated plants the number of tillers, leaf area and the number of spikes per plant were reduced respectively by 35.5%, 28.3% and 30% ( p ≤ 0.05). n TiO 2 stimulated plant growth and compensated for the adverse effects of n CeO 2 . Concentrations of Ce and Ti in aboveground plant fractions were minute. The fate of nanomaterials within the plant tissues was different. Crystalline n TiO 2 aggregates were detected within the leaf tissues of barley, whereas n CeO 2 was not present in the form of nanoclusters.
