| Abstract: | The characteristics of element concentrations in Rheum palmatum and R. likiangense plants and soil were studied using ICP method. The results showed that the P concentrations in soil was significantly lower than that in leaves and rhizomes; Fe concentration was 50-100 times higher in soil than in rhizomes, and leaves, and without significant difference between rhizomes and leaves; Na, Mn and Cu concentrations appeared soil > leaves > rhizomes; and Ca concentration showed soil < leaves < rhizomes for R. palmatum, and soil > leaves > rhizomes for R. likiangense. Although K, Mg, Ca, Mn and Zn concentrations were obviously different between soils of the 2 species, K and Mg concentrations were consistent in their leaves or rhizomes, and the difference of Ca, Mn and Zn concentrations between their rhizomes was insignificant. |
