### Effect of AMF on Plant Mineral Nutrient Status  
The plant mineral nutrients include macroelements and microelements. In terms of the macroelements, inoculation with _G. mosseae_ significantly increased K concentration in _S. miltiorrhiza_ shoot by 24.3%. The inoculated _S. miltiorrhiza_ showed reduced P concentrations in the shoots and roots and Mg concentration in the roots. Significant differences were not observed in the concentrations of N and Ca in the shoots and roots, and Mg in the shoots between the AMF-inoculated plants and the control plants (Table 3).  
Inoculation with _G. mosseae_ produced a more pronounced effect on the plant microelements than on the macroelements. Inoculation with _G. mosseae_ significantly increased Mn concentration in the

shoots (by 93.4%) and roots (by 65.1%) and Fe concentration in the roots (by 75%) of _S. milliorrhiza_. The inoculated _S. milliorrhiza_ showed a reduced Fe concentration in the shoots. Significant differences were not observed in the concentration of Zn in the shoots or roots between the AMF-inoculated plants and the control plants (Table 3).
