Fig 8. Cerium concentrations in rice plants during the vegetative stage in response to Ce treatments.

Ce concentration in shoots (A) and roots (B) of rice cv. Morelos A-98 plants treated with 0, 25, 50, or 100 μM Ce. Cerium was supplied as CeCl₃ 7H₂O. Bars represent means of 26-d-old plants grown in the nutrient solution for 28 d. Means ± SD with different letters in each variable indicate statistical differences among treatments (Duncan, P ≤ 0.05).
