Fig. 7From: Effect the accumulation of bioactive constituents of a medicinal plant (Salvia Miltiorrhiza Bge.) by arbuscular mycorrhizal fungi communityThe increase of TP and TTS concentrations in S. miltiorrhiza roots compared with CK. (a) the concentration of TP, and (b) the concentration of TTS. Different compositions of thirty-two groups were used in this study as Fig. 2b. "*" indicates a significant difference (p < 0.05), and "**" indicates a highly significant difference (p < 0.01) when compared with CKBack to article page
