Fig. 1

Effect of sulfur addition on content of sulfur (mg·kg−1) in grain (filling) and brown rice (maturity) (a), husk (a), leaves (b), stems (c) and roots (d) at the booting, filling and maturity stage of rice exposed to Cd-contaminated soil. Values are mean ± standard deviations. Different letters indicate significance at p < 0.05 (LSD) for different stage under the same treatment. *, ** indicate difference of index between –S and + S treatments at p < 0.05, 0.01, respectively. –S without S supply, + S with S supply
