Abstract
Experiments were carried out to select the rusty tolerance lines in 39 inbred lines of ginseng cultivated in field, among them, 7 lines showed low degree of rusty root while 7 lines showed high degree of rusty root. In order to select marker elements among mineral nutrients for rusty ginseng root, we combined 5 groups as follows : Ⅰ (healthy-root of low rusty degree lines vs. rusty-root of high rusty degree lines), II (healthy-root vs. rusty-root in low rusty degree lines), Ⅲ (healthy-root vs. rusty-root in high rusty degree lines), Ⅳ (low rusty degree lines vs. high rusty degree lines in rusty-root), Ⅴ (low rusty degree lines vs. high rusty degree lines in healthy-root), and analyzed mineral nutrition at different root parts. The contents of mineral nutritions in stele and cortex were not different between healthy lines and rusty lines, and between healthy roots and rusty roots, but that in branch and fine roots were not a tendency. The contents of Fe, Na and Al in epidermis were higher in rusty-root than healthy-root. Also, the contents of Fe and Al in epidermis of high rusty degree lines (HRL) were higher than those of low rusty degree lines (LRL) in healthy-roots and rusty-roots, and so we suggest Fe and Al as markers to select low rusty degree ginseng lines.
