  • The characteristics of the areal parts, photosynthetic and respiration rates and stem color were examined in 1- to 5-year-old Green-stem, Violet-stem and Yellow-berry variant ginseng (Panax ginseng C.A. Meyer). The top characteristics, photosynthetic and respiration rates were not significantly different among the three variants. Selfed progency of the Green-stems variant plant produced only green stems, while the others produced green and violet stem in the seedling stage. These results showed that most of the top characteristics of the Green-stem variant were similar those of the Violet-stem and Yellow-berry variants with age.

  • These experiments were conducted to investigate the nematicidal effects of the insecticides, Mocap(O-Ethyl-S, S-dipropyl phosphorodithioate), Carbofuran(2,3-Dihydro-2,2-dimethyl benzofuranyl ethyl carbamate), Terbufos (S-tert-buthylthio methyl O,O-diethyl phosphordithioate) and their mixtures (Mocap+carbofuran, Mocap+Terbufos, Carbofuran+Terbufos) on growth of 2year-old ginseng, Panax ginseng C.A. Meyer, and the control of root-knot nematodes. There was no evidence of plant injury from insecticide treatment of ginseng, although the rate of emergence of the treated ginseng was slightly inhibited. The insecticide treatments showed no of-flavor of ginseng plant. Terbufos and Mocap provided heifer confrol of the root-knot nematodes than carbofuran alone and their mixtures. Mixtures of the insecticides showed antagonisitic effect to the root-knot nematodes.

  • This study was conducted to investigate chemical and physical characteristics of pectin in Korean ginseng plant. The results obtained are as follows: 1, The molecular weight of the pectin in ginseng plant was in the range of 1.1-2.4x 104 and athydrouronic acid content in the pectin was 97.98%. 2. The intrinsic viscosity of pectin as well as apparent visosity of the pectin in the roots were increased with cultural period. 3. The IR spectra of ginseng pectin showed the OH stretch, C-H bending vibration and the vibration of ester group carboxyl. 4. Sugars present in galacturonic acid, glucose, arbinose, xylose, galactose and rhamnose.
