a) The nutrient element (AN: alkali hydrolyzable nitrogen, AP: available phosphorus, AK: available potassium, ECa: exchangeable calcium, EMg: exchangeable magnesium) concentrations in the soils at two sites (L and D) (mg/kg); b) Percentage of nutrient element (N: nitrogen, P: phosphorus, K: potassium, Ca: calcium, Mg: magnesium) concentrations in the roots at the two sites (L and D); c) Percentage of nutrient element (N, P, K, Ca and Mg) concentrations in the stems; d) Percentage of nutrient element (N, P, K, Ca and Mg) concentrations in the leaves. One asterisk in the figure indicates a significant difference in elements in the roots or other tissues between sites D and L (p < 0.05), while two asterisks indicate a highly significant difference (p < 0.01)
