Root fungal endophyte inoculation increased C. barbinervis seedling growth in the inoculation test.
Seedlings were grown for 40 days in sterilized heavy-metal-polluted soil. Scale bar represents 10 mm.

Nutrient element concentrations in C. barbinervis seedlings in the inoculation test.
(a) Concentrations in aboveground parts, and (b) concentrations in roots. Different letters indicate a statistically significant difference among treatments in ANOVA comparisons and the post-hoc Tukey HSD at P < 0.05. Error bars represent ± SE.

(a) Concentrations in aboveground parts, and (b) concentrations in roots. Different letters indicate a statistically significant difference among treatments in ANOVA comparisons and the post-hoc Tukey HSD at P < 0.05. Error bars represent ± SE.
