Characterization of tobacco under different Se and Cd concentration supply conditions for 21 days. (A) The phenotype of shoot, third young leaf and root under Se (Ⅳ) and Cd (Ⅱ) treatments in tobacco; (B) The biomass of shoot under different Se (Ⅳ) and Cd (Ⅱ) concentration supply conditions; (C) The biomass of root under different Se (Ⅳ) and Cd (Ⅱ) concentration supply conditions. 14-days-old seedlings (wild-type, Yunyan 87) were grown in pots with sand under different Se (0, 10, 50 μM) and Cd (0, 20, 50 μM) concentrations for 21 days. Se0: no Se; Se10: Se, 10 μM; Se50: Se, 50 μM; Cd0: no Cd; Cd20: Cd, 20 μM; Cd50: 50 μM. Shown are mean ± standard deviation (SD) from five biological replicates. DW, dry weight. Different letters indicate significant differences (p < 0.05).
