This study was conducted to know the influence of plant age and cultural conditions such as plant population density and light intensity under the shading on the leaf shape of panax ginseng. The result obtained were as follows; 1) Leaf length(L)/maximum width(W) was no difference with different age of over 3-over 3year old plant, but that of 1 or 2-yearold was smaller than those of over 3-year old. The values of L/W showed in the order of 2 or 4,3, 1 or 5 leaflet. 2) Ratios of leaflet area to leaf area were 32.0% in leaflet 3, from 209.% to 27.9% in leaflet 2 or 4, and from 6.5% to 7.1% in leaflet 1 or 5. 3) The coefficients of variability for L/W and ratio of leaflet area to leaf area of leaflet 3 were smallest among leaflets. 4) There were significant differences between largest and smallest leaflet 3, leaf areas and ratio of leaflet 3 area to leaf area in same plant. 5) LW and ratio of leaflet 3 area to leaf area were not affected by plant population density. 6) It showed a tendency that the L/W was increased with increasing the light transmittance rate (LTR). The ratio of leaflet 3 area to leaf area of ginseng grown under 20% LTR was not different comparing to that of plant grown under 5% LTR, but it was significantly increased in plant grown at 100% LTR.

본 연구는 7년, 13년근 산양삼의 생육특성과 진세노사이드(G) 함량 간의 상관관계를 구명하기 위하여 수행되었다. 6개소의 산양삼의 생육특성을 조사한 결과, 뇌두길이, 뿌리길이, 생중량, 단면적, 표면적, 부피에 있어 13년근 산양삼이 7년근 산양삼에 비하여 유의적으로 높은 것을 확인하였다. 진세노사이드 11종에 대한 함량은 G-Rb1, Rb2, Rc, Rd, Re, Rf, Rg1, Rg2 함량이 13년근 산양삼이 7년근 산양삼 보다 유의적으로 높은 수치를 확인하였다. 또한 산양삼과 인삼(재배삼) 진세노사이드 함량을 비교한 결과, 13년 산양삼에서 G-Rb1, Rd, Re, Rf, Rg1이 4년, 5년근 인삼(재배삼)에 비해 유의적으로 함량이 높은 것으로 확인되었다. 산양삼 연근별 생육특성과 진세노사이드 함량 간의 상관관계를 분석한 결과, G-Rb1, Rb2, Rc, Rd, Re, Rf, Rg1, Rg2 함량은 뇌두길이, 생중량, 단면적, 표면적, 부피와 유의정인 정의 상관관계를 보였으며, G-Rb1, Re, Rf, Rg2는 줄기직경과 부의 상관관계를 확인하였다. 본 연구는 산양삼의 7년근과 13년근을 대상으로 생육특성과 진세노사이드 함량 상관관계를 구명함으로써 연근에 따른 품질규격 정립에 유용한 정보를 제공 할 것으로 판단된다.

Specific activities of ADC and ODC from 2-4 year old ones were higher than that from seedlings whereas those activities were not changed significantly from 2 to 4 years. Generally, activity of ADC was predorminant compared to that of ODC. Free arginine content in roots was much higher than that of leaves. And arginase specific activity from roots was higher than that of leaves. Cumulative results suggest that putrscine formation from ornithine in roots may be more effective than leaves and contribute to putrescine biosynthesis to some extract.

Background: The Panax ginseng plant is used as an herbal medicine. Phytosterols of P. ginseng have inhibitory effects on inflammation-related factors in HepG2 cells. Methods: Phytosterols (e.g., stigmasterol and ${\beta}$-sitosterol) in the roots of P. ginseng grown under various conditions were analyzed using high-performance liquid chromatography. The P. ginseng roots analyzed in this study were collected from three cultivation areas in Korea (i.e., Geumsan, Yeongju, and Jinan) and differed by cultivation year (i.e., 4 years, 5 years, and 6 years) and production process (i.e., straight ginseng, red ginseng, and white ginseng). Results: The concentrations of stigmasterol and ${\beta}$-sitosterol in P. ginseng roots were 2.22-23.04 mg/g and 7.35-59.09 mg/g, respectively. The highest concentrations of stigmasterol and ${\beta}$-sitosterol were in the roots of 6-year-old P. ginseng cultivated in Jinan (82.14 mg/g and 53.23 mg/g, respectively). Conclusion: Six-year-old white ginseng and white ginseng cultivated in Jinan containing stigmasterol and b-sitosterol are potentially a new source of income in agriculture.

Background : Ginseng is mainly grown as a break crop in paddy fields after rice has been cultured for approximately 4 - 5 years, because it reduces the negative effects of continuous rice cropping. However, physiological disorders, such as leaf discoloration, occur in ginseng grown in paddy fields with poor drainage and excessive levels of inorganic components. Methods and Results : This study investigated the effect of ridge height on the growth characteristics and yield of 6 year old Panax ginseng. Ridge height was varied by making 20, 30, and 40 cm high ridges in a pooly drained paddy field. Soil moisture content decreased, while electrical conductivity (EC) as the ridge height increased. The $NO_3$, K, Ca, Mg, and Na levels also rose as ridge height increased, but organic matter and $P_2O_4$ levels did not. The leaf discoloration ratio rose as the ridge height increased, and root yield reached a peak when the ridge height was 30 cm. Conclusion : A ridge height of 30 cm in poorly drained paddy field improved ginseng growth by reducing leaf discoloration and increasing root survival, owing to more suitable soil moisture and EC levels.

Six-year-old ginseng roots were divided into rhizome, main root (epidermis, cortex and xylem) and lateral root (big tail root, mid tail root and fine tail root) and the concentration levels of soluble dietary fiber (SDF) and insoluble dietary fiber (IDF) in each part of the ginseng were investigated. The amount ratios of SDF to IDF (SDF/IDF) in various parts of the ginseng root were also compared. The concentration levels of SDF and IDF in the ginseng root were 6.56% and 15.41 %, respectively, where the level of SDF in main root was a little higher than that of lateral root. However the amount of IDF in main root was lower than that of lateral root. The SDF/IDF was highest in main root, 0.513, which was higher than that of lateral root or rhizome. The SDF/IDF was 0.704 in xylem, 0.478 in cortex, and 0.099 in epidermis of the main root and the SDF/IDF was 0.576 in big tail root, 0.463 in mid tail root, and 0.255 in fine tail root of the lateral root. It has been reported that SDF might have preventive effects on diabetes, obesity, high blood pressure, colon and rectum cancers, while IDF might have preventive effects on constipation. Therefore, main root of six-year- old ginseng root is thought to have a little different physiological activity from lateral or fine tail roots.
