The quality of raw, red and white ginseng and the contents of some minerals were examined using 6-year-old ginseng roots produced in different shades, thatch and polyethylene net (P..E.). The yield of first and second grade ginseng roots was higher in the thatch shade than in the P.E. shade. The smaller sizes of ginseng routs were probably due to loss of ginseng yield called by alternaria blight in the third and fourth years, and lower quality was dale to more rusty roots in the P.E. shading. For red ginseng. rates of heaven and earth grades were higher in the P.E. than thatch shade. producing red ginseng with less inside cavity Production of white ginseng was higher in the thatch shade than in the P.E. shade. showing a higher yield, better piece grade, lower inside crack and better quality index in the thatch. The contents of some minerals such as K, Ca, Mg and Mn of fine ginseng roots differed between the two shades, some of which had a significant correlation with the quality indices of white ginseng. Keywords Thatch shade, polyethylene shade, alternaria blight, rulsty root, quality of ginseng.

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.

천연생물자원으로부터 적변억제 효과가 우수한 ICPE-P$_{107}$R와 ICPE-C$_{105}$R을 선발하였고 실험 포장에서 1년생 묘삼을 식재하여 2년간에 걸친 인삼의 적변현상 억제 효과를 검증하였다. 그 결과 방제물질과 보조제를 조합한 방제물질 처리구에서 인삼의 생장이 우수하였는데 특히 ICPE-P$_{107}$R와 ICPE-C$_{105}$R에서는 건물중이 대조구의 1.15g dry wt. x ginsen$^{-1}$보다 더 많은 1.99g dry wt. 와 1.47g dry wt. 로 생장 증가를 나타내었다. 또한 적변 억제 효과에서 방제물질 ICPE-P$_{107}$R 와 ICPE-C$_{105}$W가 각각 20%, 13.3%로 대조구 58%에 비해 놀라울 정도로 높은 방제 효과를 나타냈으며 ICPE-C$_{105}$R, ICPE-C$_{105}$P에서도 16.7% 18.2%로 비교적 양호한 효과를 나타내었다. 총 ginenoside의 함량과 각 ginsenoside의 함량역시 모든 방제제 처리구에서 대조구보다 공히 더 높은 함량을 나타내었다. 특히 ICPE-C$_{105}$R, ICPE-P$_{107}$R 처리구에서는 대조구보다 조사한 ginsenoside의 종류와 총 함량에 있어서 모두 월등하게 더 높았다.

본 연구는 접종방법, 상토 및 유기물의 종류, 토양수분, 세균밀도가 적변발생에 미치는 영향을 조사하여 적변발생 요인 및 원인을 밝히기 위하여 실시하였다. 1. Hue value는 무상처 무접종에서 113.1, 무상처 접종 108.1, 상처 무접종 85.8, 상처접종 57.5로 적변은 무상처 무접종 < 무상처 접종 < 상처 무접종 < 상처 접종 순으로 심하게 발생하였다. 2. 원예용 상토와 수도용 상토에서 Hue value는 각각 56.8, 64.7로 수도용 상토보다 원예용 상토에서 적변이 심하게 발생하였다. 3. 토양의 수분농도가 10%, 20%, 50%, 70%일 때 Hue value는 각각 96.2, 85.9, 78.0, 75.7로 수분이 높을수록 적변이 심하게 발생하였다. 4. 유기질 비료를 첨가한 토양에서의 Hue value는 35.2-27.8로 유기질 비료의 시용은 적변 발생을 심하게 유발하였다. 5 세균접종 농도가 $10^{2},\;10^{4},\;10^{6},\;10^{8}\;cells/m{\ell}$일 때, Hue 값은 각각 63.3, 62.8, 55.6, 48.8로 세균농도가 높을수록 적변의 발생이 심하게 발생하였다.

The development of cracking in ginseng roots was studied to elucidate the factors affecting it in the field. The cracking of 6-year-old ginseng roots harvested in late October callld be induced in 2 days after soaking in water or in watersatllrated soil. However, it callld be slowed down by approximately 10 days when the roots were kept at a low temperature(5$^{\circ}C$). Roots excavated in late May did not develop cracking tinder the conditions tested. There was no significant difference between rice-straw shade and P.E. net shade in the rate of cracked ginseng roots. Which varied with ginseng varieties in relation to shade material. The rate of cracked roots was about 40% in 6-year plants, but it was extremely high (55.6%) in rusty roots. Healing of the wound formed by cracking was generally low but varied between harvest years.

This study was conducted to find out the optimum composition of nursery soil for raising seedling of ginseng (Panax ginseng C. A. Meyer). Total 9 kinds of raw materials were used such as peat-moss, perlite, leaf mould, rice bran, gull's guano, castor-oil plant bark, palm bark, cow manure and chicken manure for optimum composition of nursery soil in ginseng. Occurrence of damping-off in ginseng was lowered about 50% in nursery soil type 1, 2 and 4 than in other types nursery soil in June, and occurrence rate of rusty root also lowest in nursery soil type 1. As the salinity of nursery soil increased, so did the occurrence of physiological disorder in ginseng seedling. The cause of salinity increasing in nursery soil has closely relation to $NO_3-N$, $P_2O_5$ and $Na^+$ content. Plant height, root length, diameter and weight were longer and heavier in nursery soil type 1 (mixing ratio of peat-moss, perlite and leaf mould was 50 : 20 : 30 based in volume) than in other types of nursery soil. So nursery soil type 1 was selected for raising seedling of ginseng. pH and electric conductivity (EC) of selected nursery soil type 1 was 5.55 and 0.13 dS/m. Contents of $NO_3-N$ and $P_2O_5$ were 21.0 and 40.0 mg/L, and $K^+$ 0.36, $Ca^{2+}$ 3.38, $Mg^{2+}$ 2.01 and $Na^+$ $0.09cmol^+/L$, respectively.

본 연구는 Panax속의 유용형질을 탐색하고, 고려인삼과 미국삼, 그리고 종간 잡종인 F$_1$ 식물체의 생육, 형태적 특성, 수량, 적변율 및 ginsenoside함량 등을 조사하였던 바, 그 결과를 요약하면 다음과 같다. 1. 고려인삼은 적변 발생율이 연생이 높아질수록 증가하였으나, 미국삼은 적변이 발생되지 않았으며 F$_1$잡종식물체에서도 적변이 발생되지 않았다. 2. 고려인삼과 미국삼의 잡종인 F$_1$잡종식물체 인삼의 개화기는 미국삼보다 빠르고, 자경종보다는 늦었다. 3. 고려인삼과 미국삼을 교배한 F$_1$ 묘삼의 근형질 특성은 미국삼과 고려인삼에 비하여 근장과 근중이 컸다. 4. 잡종 F$_1$의 ginsenosides 함량은 대부분이 고려인삼과 미국삼의 중간 정도였으나, 양친보다 Re는 많았고 Rg$_1$, Rg$_2$ 는 적게 정량 분석되었으며, Rf가 고려인삼에서는 검출되었으나 미국삼 및 F$_1$잡종식물체에서는 검출되지 않았다.
