Figure 1. Leaf glucose content in mustard after treatment with Cd and/or S treatments at 30 d after sowing. Plants were grown with 0, 200 mg Cd kg⁻¹ soil (200 Cd), 100 mg S kg⁻¹ soil (200 S) or 200 mg S kg^-1 soil (200 S) with combined Cd and S treatments. Means values ± SE are shown (n = 4). Means denoted by the same letter are not significantly different at p < 0.05 according to least significant difference test. Cd, cadmium; DW, dry weight; S, sulfur.
