Fig 4. Growth of rice plants exposed to different Ce concentrations.

Fig 4

Plant height (A), number of tillers (B), root length (C), and root volume (D) of rice cv. Morelos A-98 plants treated with 0, 4, 8, or 12 μM Ce. Cerium was supplied as CeCl3 7H2O. Bars represent means of 26-d-old plants grown in Yoshida nutrient solution for 28 d. Means ± SD with different letters in each variable indicate statistical differences among treatments (Duncan, P ≤ 0.05).
