Varietal Difference in Growth Response and Ginsenoside Contents of Two-Year-Old Ginseng Grown in Paddy Field with Different Drainage Conditions

To select adoptable varieties in paddy soil with relatively high content of soil moisture, the growth characteristics and ginsenoside content of two-year-old gin-seng was investigated in paddy soil with two types of drainage conditions such as poorly and imperfectly drained class, using 4 varieties, Cheonpoong (CP), Yeonpoong (YP), Hwangsookjong (HS) Jakyeongjong (JK). The ratio of survived plant in poor drainage conditions was higher than that in imperfect drainage conditions, and the ratio of dis-colored leaf in the former was lower than that in the latter. The ratio of survived plant was highest in HS, while lowest in YP. The ratio of discolored leaf was lowest in HS, while highest in YP among 4 varieties. Root weight per plant and yield were more distinctly decreased in poor drainage con-ditions than those in imperfect drainage conditions. Descend-ing order of yield in poor drainage conditions was JK, CP, YP and HS, while CP, YP, JK and HS in imperfect drainage conditions. Varietal difference of rusty colored root was more distinct than that between poor and imperfect drainage conditions. The ratio of rusty colored root was relatively low in CP and JK, while high in YP and HS. Total ginsenoside content of two-year-old ginseng grown in poor drainage conditions was increased more than that in imper-fect drainage conditions due to full growth of root. Regard-less of different drainage conditions total ginsenoside con-tent was highest in YP, while lowest in HS among 4 varieties, and there were no distinct difference between CP and JK.
