To know possibility of raw ginseng production for white- and red-ginseng by direct-sowing culture, seeds were directly sowed or seedlings were transplanted at soil condition of sandy loam in ginseng field. After cultivation, the characters of 5-year-old ginseng were investigated. Number of survived plants was increased with increase the seeding quantity in direct-sowing culture, the survived plants in direct-sowing culture was higher than that of transplanting one. Rate of the numbers of survived plants to numbers of seeds sowed in plots of 134 or 90 seeds sowed per tan, 180 x 90cm area, inspire of high number of survived plant was high compared to that of transplanting culture. Occurrence rate of rusty root of ginseng in direct-sowing culture was low significantly compared to that of transplanting culture. Root yield showed in the order of 134, 268, 90 seeds sowed, the values of yield in direct-sowing culture were high obviously compared to that of transplanting one. Individual root weight was increased with decrease the seeding quantity, however, the root weight in plot of 90 seeds sowed showed almost equal the weight in transplanting culture. The number of usable raw ginseng for white- and red-ginseng was increased with decrease of the seeding quantity; the numbers were higher than that of transplanting culture remarkably. We concluded that optimum seedling rate in direct-sowing culture of ginseng was 90 to 134 seeds per tan considering the yield per area and production rate of large root.

Hairy root culture of ginseng is industrially prospected because the cultivation period of ginseng is relatively long. In this study, the effect of medium concentration and sucrose concentration on hairy root culture of ginseng was evaluated. The optimization of ginseng hairy roots transformed by Agrobacterium rhizogene were performed liquid medium. The MS(Murashinge & Skoog basal medium) concentration was selected with 1/2 strength MS and the optimal sucrose concentration was determined at 2-3%(w/v). At the optimum culture condition, The yield (the ratio of weight of grown hairy root cultures to weight of fresh ginseng hairy roots) and production rate of ginseng root were 19.42 times and 5.73 g/l-day. The major ginsenosides were Rb group, Re and Rg1. The produced total ginsenoside content in the solid medium was 9.87 (mg/g) and increased 1.34 times in the liquid medium (13.23 mg/g). In solid culture, the contents of ginsenosides Rb, Re and Rg1 were 2.14, 3.65 and 1.87 mg/g, respectively. In liquid culture, the contents of ginsenosides Rb, Re and Rg1 were 3.54, 4.12 and 2.63 mg/g, respectively.

식물조직배양기술을 이용하여 인삼 root를 생산하고자, 식물생장조절물질로 유도된 인삼 root를 사용하여 최적액체배양조건을 RSM을 이용하여 조사하였다. 최적액체배양조건을 배지의 pH, sucrose 농도, nitrogen 농도, phosphate 농도의 3 level-4factor의 fractional factorial design에 의하여 조사한 결과, 인삼 root의 생장율은 최저 1.00g에서 최고 2.33g까지 나타났다. 다중회기분석으로 구한 model식을 가지고 등고분석과 3차원분석을 수행한 후 독립변수의 최저 또는 최고수준에서 조속변수가 최대치를 나타내지 않는 배지의 pH와 sucrose농도의 변수에 대하여 model식을 편미분한 결과 인삼 root의 최적액체배양조건은 pH5.6, sucrose 3.8%, nitrogen 50mg/L, phosphate 80.7mg/L로 예측되었다. 이렇게 결정된최적조건값들을 model식에 대입하여 얻은 예상치는 2.36g 이었다.

식물조직배양기술을 이용하여 사포닌 함량이 높은 인삼 root를 생산하고자, 인삼 root의 생장과 사포닌생산에 미치는 배지와 식물생장조절물질의 영향을 조사하였다. 인삼 root를 여러 종류의 배지에 배양하였을 때, 인삼 root의 생장과 사포닌 생산은 SH배지에서 가장 우수하였고, SH배지에 배양시, 접종후 약 10일후에 생체중량이 초기접종량의 2배가 되었다. 각 배지별로 배양한 인삼 root의 진세노사이드 패턴과 함량은 다소 차이가 있었는데, SH배지와 White배지에서 성장한 인삼 root의 총진세노사이드 함량이 가장 높았다. 생장조절물질에 있어서는 4.0mg/L NAA를 함유한 SH배지에서 성장한 인삼 root의 생장이 가장 우수하였고, 사포닌 함량은 0.5mg/L BAP 처리구에서 가장 높았다. 이러한 결과들은 인삼 root 배양에 의해 사포닌을 단기간에 생산할 수 있는 가능성을 제시하고 있다.

The effect of ginseng saponin on chick embryonic dorsal root ganglia organ culture and brain, spinal cord, muscle dissociation cultures was studied. The fiber outgrowth in explanted chick embryonic dorsal root ganglia was markedly induced by water and alcohol extracts of ginseng, total ginseng saponin, protopanaxadiol and protopanaxatriol glycosides as well as ginsenosides R/sub b1/, R/sub d/, R/sub 0/+R/sub a/+R/sub b1/, and R/sub b2/+R/sub c/+R/sub e/ mixtures. The life span of the cultured chick embryonic dorsal root ganglia and potentiation of nerve cell density were also observed with all of these ginseng saponins. The effect of ginseng saponin on chick embryonic dorsal root ganglia organ culture was more marked in the absence of the chick embryonic extract which was known to contain nerve growth factor-like material in the culture media. However, the ginseng saponin did not influence the cultured central nervous system such as brain and spinal cord cells and cultured skeletal muscle cells with respect to the morphological changes, maturation and life span of these cells.

In order to pursue some physiological studies on organogenesis in ginseng tissue culture, ginseng root explants were cultured on a modified MS medium containing NAA and kinetin. The activities of peroxidase and some enzymes were investigated and their isoenzyme patterns were also observed. The activity of peroxidase decreased by 20% in one week's culture and increased thereafter by 80% in culturing for 7 weeks compared with the control group. Glucose-6-phosphate dehydrogenase activity increased by 400% after culturing for 5 weeks and increased during the days preceeding root formation. The activities of glutamate dehydrogenase and acid phosphatase also increased during the culture. After 3 weeks' culture, new peroxidase isozyme (pH 7.6) appeared and 7 weeks' culture, another new peroxidase isozyme (pH unidentified) appeared. These patterns were also identified by using FPLC. After 7 weeks' culture, a new esterase isozyme of pH 8.5 appeared and isozyme patterns of acid phosphatase were quite changed compared with the isozyme patterns of tissue cultured for 5 weeks. In so far as these new isoenzymes appear distinctively after 7 weeks' culture, root differentiation is supposed to be induced after 7 weeks' culture.

인삼모상근의 생장에 영향을 미치는 auxin과 CH의 효과를 규명하기 위하여 auxin류인 IBA, MA, NAA와 아미노산 화합물인 CH를 각각 농도별로 처리하여 MS 고체배지와 액체배지에서 50일간 배양후 수거하여 생중량과 건중량을 측정하여 농도별로 생장률을 측정한 결과, 인삼모상근의 생장에 미치는 auxin의 효과는 고체배양시에는 IBA를 1 mg/L의 농도로 암배양하는 것이 가장 효과적이었으며, NAA 1 mg/L의 농도로 광배양 하는 것도 효과적이었다. 반면에 IAA와 CH는 인삼모상근의 생장에 효과가 없었다. 액체배양시에는 IAA와 NAA를 처리했을 때 농도의 증가에 따른 생장의 증가는 보이지 않고 생장의 감소 없이 거의 일정하게 그 수준이 유지되었으며 IBA와 CH는 모두 인삼모상근의 생장을 오히려 억제하는 경향이었다.

인삼모상근의 생장과 glnsenosides 함량 증가에 미치는 chitin 및 chitosan의 효과를 규명하기 위해, 식물생장조절제가 첨가되지 않은 1/2 MS 배지에 chitin과 chitosan의 농도와 처리시기를 달리하여 인삼모상근을 배양하였다. 인삼모상근 생장은 chitin 1 mg/L의 농도에서 가장 양호하였으나 20mg/L 이상 농도에서는 생장이 감소되었다. Ginsenosldes 함량과 생산성은 40 mg/L 첨가시와 배양3주 째 처리구에서 가장 높았다. Chitosan 역시 1 mg/L의 농도에서 인삼모상근의 생장이 가장 높았으나 ginsenosides 함량은 30 mg/L 처리구에서 가장 높게 나타났고 배양 후 처리시기는 ginsenosides의 함량증가에 큰 영향을 미치지 않았다.

This study was carried out to obtain the basic information about the large scale propagation of ginseng (Panax ginseng C.A. Meyer). Therefore, the stem cuttings of 1-year old ginseng, treated with various concentrations of plant growth regulators for 5 seconds (quick dipping) and 24 hours (prolonged soaking), were cultured. The root formation of stem cuttings was varied with the concentrations, kinds, and treatment methods of plant growth regulators. Besides normal-looking roots various malformed roots were observed. In the prolonged soaking method, the culture of stem cuttings, treated with 10 ppm of IBA or NAA, resulted in profuse root regeneration. And stem cuttings, in quick dipping method, treated with 2000 ppm of IBA or NAA resulted in more excellent root regeneration. In general, IBA was more vigorous for the root formation than NAA, The treatment with 50 ppm kinetin or 100 ppm BA brought good result for the retardation of senescence of stem cuttings and BA treatment was more effective than kinetin. As for the saponin content of roots derived from stem cutting culture, the roots, formed by non-treatment of growth regulators, were higher in saponin content than those formed by treatment of growth regulators.

To investigate the effect of culture conditions on growth and ginsenosides accumulation, we cultured the ginseng hairy root under three different media, white light or ultra-violet irradiation. The MS/B5 medium containning MS basal salt and B5 vitamin was good for the growth and ginsenoside accumulation. The light during the culture period of ginseng hairy root was irradiated. The growth was abundant in the ginseng hairy root cultured in dark. But the ginsenosides accumulation was higher than in the ginseng hairy root cultured in the light irradiation. When the ginseng hairy root was cultured in 20 L bioreactor, the ginsenosides accumulation was observed at 34% higher than the hairy root cultured in dark. UV irradiated the ginseng hairy root during the culture period. The long time irradiation of UV was caused decreasing the growth of ginseng hairy root, but the accumulation of ginsenosidess was increased as to the irradiated time.
