The effect of CA on endogenous H2S content in the roots of tobacco seedlings under Cd stress. The roots of seedlings were treated with distilled water (control), CdCl2 (20 μM), CA (20 μM), NaHS (20 μM), PAG (2 μM), HT (20 μM), alone or their combinations for 72 h. Then the roots were loaded with WSP-1 for the observation of green fluorescence and the quantification of fluorescent density. Bar = 0.5 mm. Different letters indicated that the mean values of six replicates were significantly different between the treatments (p < 0.05, ANOVA, LSD).
