본 연구는 현재 수삼수납 시 품질검사요원의 관능검사로 판정되고 있는 6년근수삼의 적변판정에 대하여 영상분석기를 이용한 수삼의 적변 자동판정 시스템을 개발하고자 수행하였다. 영상분석기에 의한 수삼 총면적에 대한 grey valuequf 면적비율을 조사하여 이에 대한 회귀 및 판별분석을 실시한 결과, 정상삼과 적변삼을 구별할 수 있는 임계값은 총 면적에 대한 grey value 148에서의 면적비율(G148)로 분석되었으며, 임계값인 G(148)을 이용하여 다음과 같은 판별식을 구하였다. 적변삼의 판별식 : 6.67951$\times$G(148)+3.74122, 정상삼의 판별식 : 2.85942$\times$G(148)+9.95612, 본 판별식의 적중율은 89.8%로 이는 앞으로 계속적인 연구로 적변삼의 판정 적중율을 증가시킬 수 있을 것인 바, 컴퓨터 등 기계에 의한 적변 자동판정의 가능성은 매우 클 것으로 사료된다.

Hairy roots were induced from Korean ginseng (Panax ginseng C. A. Meyer) root explants and studied for their gene expression. A total of 3,000 ESTs (expressed sequence tags) from ginseng hairy root were determined and about 2,700 ESTs have a length of readable sequence, which result in 1,352 unique ESTs sequences. The 879 ESTs showed significant similarities to known nucleotide or amino acid sequences in other plant species, which were divided into eleven categories depending upon gene function. The remaining 473 sequences showed no significant matches, which are likely to be transcripts or to be matched to other organisms. The results indicated that the analysis of the ginseng hairy root ESTs by partial sequencing of random cDNA clones may be an efficient approach to isolate genes that are functional in ginseng root in a large scale. Our extensive EST analysis of genes expressed in ginseng hairy root not only contributes to the understanding of the dynamics of genome expression patterns in root organ but also adds data to the repertoire of all genomic genes.

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.

This study investigated the phenolic, flavonoid, and vitamin constituents in the main root, root hair, and leaf of ginseng. The total individual phenolic and flavonoid contents were the highest in the leaf, followed by the main root and root hair. Ferulic acid and m-coumaric acid were found to be the major phenolics in the main root and root hair, while p-coumaric acid and m-coumaric acid were the major phenolics in the leaf. Catechin was the major flavonoid component in the main root and root hair, while catechin and kaempferol were the major flavonoid components in the leaf. Pantothenic acid was detected in the highest quantity in the non-leaf parts of ginseng, followed by thiamine and cobalamin. Linolenic acid and menadione were the major components in all parts of ginseng.

3년생 인삼에서 5, 10 및 20% 투광율 일복간에는 경장, 경직경, 엽면적, 근장의 차이가 없었고 근직경은 10% 및 20% 일복구에서 현저히 굵었으며 20%구에서 근중이 가장 무거웠다. 6년생 인삼에서도 20% 일복구에서 가장 근직경이 굵었고 근장은 투광율에 영향을 받지 않았으며 20% 투광 일복하에서 가장 근중이 무거웠다 근중의 증가를 위한 최적 일복투광량은 3년근에서는 18.13% 그리고 6년근에서는 21.50% 추정되었다.

The characteristics of absorption and accumulation of inorganic germanium in Panax ginseng C. A. Meyer were examined. In 4-year-old P. ginseng, the germanium content of the field soil increased with increased amounts and frequencies of inorganic germanium application, while chemical components of the soil, such as available phosphate and exchangeable calcium, potassium, and magnesium, decreased with the increased inorganic germanium application. In the 4-year-old P. ginseng, the germanium content was highest in the rhizome and increased in the order of stem, leaf, lateral root, and main root, suggesting that inorganic germanium was absorbed from the root and translocated to the stem and leaf via the rhizome. As for changes in ginsenosides in 4-year-old P. ginseng rhizomes, the contents of ginsenosides $Rb_1$, $Rb_2$, Re, and Rf decreased as the germanium content in soil increased. Ginsenosides $Rb_1$, $Rb_2$, Rc, Re, and Rf in the main root also decreased with increasing germanium content in the main root. The results suggest that inorganic germanium treatment may increase organic germanium in harvested P. ginseng, thus enhancing the medicinal effi cacy of ginseng products.

The monoxenic culture of the fungivorous nematode, Aphelenchus avenae, was applied for the control of soil-borne ginseng pathogens such as Fusarium solani and Rhizoctonia solani. Fungivorous nematode populations were measured in a field to examine relationships between the nematode populations and suppression of ginseng root diseases. Inoculation of A. avenae (5000 nematodes per petri-dish) reduced the colonization of the Fusarium mycelium on root discs of ginseng and carrot by 80.0% and 60.5%, respectively. A. avenae also significantly reduced the occurrence of damping-off of ginseng by R. solani pathogenic to ginseng, and no plant damage by the nematode was noted. In a 3-year-old ginseng field infested with Cylindrocarpon destructans, plant missing caused by root rot positively correlated to the density of potato rot nematode, Ditylenchus destructor, but it was reduced with the population of A. avenae, suggesting that A. avenae might inhibit the occurrence of ginseng root rot.

The effects of soil phosphorus level on seed emergence, seedling mortality, plant and root development of American ginseng (Panax quinquefolium L.) were evaluated in a newly planted commercial ginseng garden. Phosphorus levels were increased from 58 ppm to 100, 150 and 200 ppm with triplephosphate (0-45-0). Higher phosphate levels increased, seed emergence and reduced seedling mortality. Root length, diameter, fresh root weight and total leaflet length were not affected by phosphate levels.

Ginseng has been used as a medicinal herb in the world for more than two thousand years. Inspection of the quality of ginseng was made since many hundred years ago. Ginseng quality has been graded by several methodes, based on saponin contents, number of ginsenosides, shape of root and tissue elaborateness. In present. ginseng products are usually evaluated by saponin contents and number of ginsenosides. On the other hand, fresh and manufactured ginseng roots such as red. white and semi-red ginseng, Taegeuk Sam, are mostly graded by root shape such as root development and skin (epidermis) color, and tissue elaborateness. which is a conventional grading method. However, the root shape grading method has a risk of overlooking real medicinal properties of ginseng. So. both the medicinal ingredients and the conventional grading method should be considered for the proper evaluation of ginseng quality. Therefore, for the establishment of better method in evaluating ginseng quality, the relationships of root shape and useful components are required to be studied.

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.
