Fig. 3. Relative value of average S concentration in the leaves at each leaf position on the plant, at flowering (left), and S concentration at each leaf position on the S deficient and sufficient plants at the same time (right). The average S concentration was obtained from all S treatments in the A horizon of the Gerais and Sambaiba soils, and the concentration in the third leaf was taken as 100%. The S deficient plants were obtained from the 2.5 mg S kg^–1 soil treatment in the A horizon of the Sambaiba soil, and the S sufficient plants were obtained from the 40 mg S kg^–1 soil treatment in the A horizon of the Gerais soil. Bars indicate standard errors.
