The absorptivity of trace elements are different for various parts of ginseng. Concentrated elements and their degrees of concentration are also different. Ca and Sr are concentrated in the main root and their degrees of concentrations increased with growing ages. The absorptivities of element are higher in rhizome and fibrous root than in main root. In addition, the dried weight of ginseng’s root increases exponentially with growing ages.展开更多
