Effects of exogenous glycerol on the Cd content, Cd transport coefficient and Cd distribution in the subcellular fractions of maize under Cd stress. Different lowercase letters indicate that there are significant differences between different treatments at the same growth period at the level of p = 0.05, the same letter means no significant difference (p > 0.05), while different letters mean significant difference(p < 0.05). (a) Cd content of maize seedlings under different treatment conditions (mg g-1 DW), (b) Percentage of Cd content of maize seedlings under different treatment conditions (%), (c) Cd content in subcellular fractioms of maize seedlings under different treatment conditions (mg g-1 DW), (d) TF of maize seedlings under different treatment conditions. Data were presented as mean ± standard error of mean (SEM). One-way ANOVA. Post hoc Duncan’s analysis. Values of p < 0.05 were regarded as statistically significant.
