Cd tolerance of tobacco conferred by P. indica. (A) Effect of P. indica on the growth of tobacco seedlings in the presence of Cd. Control: non-treated, +F: P. indica-inoculated, +Cd: Cd-treated (5 μM), +CdF: both P. indica- and Cd-treated (5 μM). The same abbreviations are used below. (B–G) Effects of P. indica on the growth parameters of tobacco seedlings under Cd stress. The bars represent the means ± SDs, n = 9. Significant differences (one-way ANOVA): lowercase letters (a–c) mean p < 0.05.
