DAPI staining (a) and fluorescence quantitative analysis (b). Con: distilled water; Cd: 200 μM CdCl₂; NaHS: 100 μM NaHS pretreatment for 24 h; NaHS + Cd: 100 μM NaHS pretreatment for 24 h + Cd treatment for 48 h. The data are means ± SE of three independent experiments. Different letters indicate significant differences (P < 0.05; Duncan’s multiple range test)
