인삼재배지 180지점으로부터 토양을 채취하여 토양산도, 유기물함량 및 유효인산함량을 측정한 결과 재배년수별 유의한 차이는 나타나지 않았다. 채취한 토양의 메탄올추출액으로 상추종자 발아실험을 실시한 결과 $5{\sim}6$년 재배지의 토양에서 종자발아나 유묘생장을 강하게 억제하는 토양추출액을 선발하였다. 선발된 토양 추출액중 발아와 유묘생장을 억제하였던 추출액은 인삼배양세포의 활력을 최대 90%까지 억제하였으나 전해물질의 누출은 증가하지 않았다. 토양추출액으로 세가지 종류의 항산화 효소 활성을 측정한 결과 superoxide dismutase는 거의 영향을 받지 않았으나, 상추유묘의 생체중억제형 토양추출액을 처리한 인삼배양세포의 peroxidase의 활성이 현저하게 억제되었고, catalase의 활성은 발아억제형 및 생체중억제형 토양추출액 모두에서 유의한 억제를 보였다.

Various rates of 2,4-D were sprayed on 2 and 3 year old ginseng plants as foliar spray to define the critical concentration. No apparent plant injury was noticable for those ginseng plants when application concentration of 2,4-D doubled the recommended dosage (70 ml/10a). Neither abnormal foliar change occurred nor any inhibition in leaf and stem growth was resulted for the plants treated with 2,4-D concentrated two times of the recommended dosage. When the rates of 2,4-D application were increased greater than this level, injury ratings increased linearly with the rates of 2,4-D application and plant you was inhibited. Ethylene gas was not produced from the ginseng plant treated with 2 times concentrated 2,4-D, however the ginseng plants produced 0.03 to 0.09 ppm ethylene gas when the rate of application were increased 3 and 4 times, respectively. On the other hand the soybean treated with the recommended amount of 21-D produced ethylene gas of 10-20 times higher compared with ginseng plants and died. Photosynthesis ability of the ginseng leaf was significantly decreased by 2,4-D foliar application but it was recovered 4 weeks after 2,4-D foliar treatment. The herbicide 2,4-D was applicated to 2,3 and 4 years old ginseng plants as foliar spray with the rates of 0.5, 1.0, 1.5 and 2.0 times of the recommended dosage to define the effects of 2,4-D on the plant growth and root yield of the ginseng. There were no significant differences in the leaf and stem growth between untreated and 2,4-D treated plant. Berry maturing of 3 and 4 year old ginseng was not influenced by 2,4-D. The root weight of 4 years old ginseng plant was not reduced by application of 2,4-D concenrated 2 times of the recommended dosage, Application time of the herbicide 2,4-D had no effects on the leaf or stem growth of 2,3 and 4 year old year old ginseng plants. When the ginseng seedling was treated with 2,4-D, detrimental phenomena as stem bending and docoration of seedling leaf margin occurred, but stem bending was recovered in a few day s. Keywords Panax ginseng C.A. Meyer, 2,4-D , herbicide.

청경종 특성을 알기위하여 지상부 제형질, 광합성과 호흡 그리고 자식세대의 경색을 조사하였다. 청경종은 엽경종, 황열종의 경, 엽, 광합성과 호흡에 뚜렷한 차이가 나타나지 않았지만 5년근시 화경장 형질이 타 변종보다 길었다. 광합성에 있어서는 청경종이 뚜렷한 차이는 없는 경향이며 비교적 황열종이 높았으나 $20^{\circ}C$ 이상에서는 모든 변종에서 현저히 떨어지는 경향이었다. 청경종내 자식세대 일부는 경색이 분리되는 경향이나 자식사대가 거듭할수록 녹색경(청경종) 출현이 높았다.

인삼에서의 polyamine의 함량과 그 합셩효소에 대해서 관찰하였다. 종자의 경우 주된 polyamine은 putrescine이며, 성장하면서 putrescine이 증가되고 있다. ADC는 putrescine의 증가와 같은 경향으로 활성도가 증가되고 있다. ADC는 활성도는 putrescine에 의해서는 별 영향을 안 받았으나, spermidine은 10%내외, spermine은 20% 정도의 inhibition을 받았다. 주로 많았으며, spermidine도 상당히 많았다. 오히려 putrescine이 상대적으로 적었다. 부위별로는 잎이 가장 많고 엽병, 뿌리 그리고 줄기 순으로 분포한다. ADC의 활성도 polyamine 함량과 같은 경향을 보인다.

Activity of endogenous growth regulator in 4th year Panax ginseng root was investigated by second leaf sheath test of rice seedling and paper chromatogram of a acidic fraction of methanol extract before (March 28) and after (May 9) emergence of root bud, at the late season (Sept.4) and after leaf fall (November 11). GA$_3$ and ABA were used as reference. According to paper and high performance liquid chromatography of samples and authentic growth regulators the presence of insole acetic acid (IAA), gibberellic acid (GA$_3$) and abscisic acid (cis and trans ABA) was confirmed. These three regulators appeared to consist of major system though the existence of other regulators could not be ruled out. IAA activity seemed little changed through out the seasons. GA activity decreased in the later stages while ABA activity increased.

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.

Various rates of 2, 4-2 were sprayed on 2 and 3 year old ginseng plants as fouler spray to define the critical concentration. No apparent plant injury was noticeable for those ginseng plants when application concentration of 2, 4-D doubled the recommended dosage (70 mil 10a). Neither abnormal fouler change occurred nor any inhibition in leaf and stem growth was resulted for the plants treated with 2, 4-D concentrated two times of the recommended dosage. When the rates of 2, 4-D application were increased greater than this level, injury ratings increased linearly with the rates of 2, 4-D application and plant growth was inhibited. Ethylene gas was not produced from the ginseng plant treated with 2 times concentrated 2, 4-D, how- ever the ginseng plants produced 0.03 to 0.09 ppd ethylene gas when the rate of application were increased 3 and 4 times, respectively. On the other hand the soybean treated with the recommended amount of 2i-D produced ethylene gas of 10-20 times higher compared with ginseng plants and died. Photosynthesis ability of the ginseng leaf was significantly decreased by 2, 4.D fouler application but it was recovered 4 weeks after 2, 4-D fouler treatment. The herbicide 2, 4-D was appreciated to 2, 3 and 4 years old ginseng plants as fouler spray with the rates of 0.5, 1.0, 1.5 and 2.0 times of the recommended dosage to define the effects of 2, 4-D on the plant growth and root yield of the ginseng, There were no significant differences in the leaf and stem growth between untreated and 2, 4-D treated plant. Berry maturing of 3 and 4 year old ginseng was not influenced by 2, 4-D. The root weight of 4 years old ginseng plant was not reduced b). application of 2, 4-D concentrated 2 times of the recommended dosage. Application time of the herbicide 2, 4-D had no effects on the leaf or stem growth of 2, 3 and 4 year old year old ginseng plants. When the ginseng seedling was treated with 2, 4-D, detrimental phenomena as stem bending and deceleration of seedling leaf margin occurred, but stem bending was recovere d in a few day.

This experiment was carried out to select suitable organic matter in To-jik nursery (self soil nursery) for complement To-jik nursery's defects that are deterioration of raw material by poor quality of seed ginseng and reduction of the quantity in seed ginseng production. Organic matter used were Yacto, rice bean, defatted rice bran, soybean cake and their mixture. As follows, bulk density in soil physical property by treating organic composts was the greatest in soybean cake and the next was followed by mix, Yacto, defatted rice bran, and rice bran treatment in order. Soil pore space ratio was totally the opposite; that was rice bran the first and followed by defatted rice bran, Yacto, mix and soybean cake treatment. The incidence rate of damping off by treating organic composts was 1.5% in both soybean cake and mix while the others was 1.0%. Emergence time was the same among treatment on April 16 and Emergence rate was the highest at 73% in Yacto. There was no significant differences among treatment in the growth of aboveground part but it was a little better in defatted rice bran treatment. In Yacto treatment, the growth of underground part, total root number per kan, rate of first grade ginseng seedling, and rate of usable ginseng seedling etc. were entirely higher but there was little differences. Using defatted rice bran was slightly lower in productivity compared to Yacto, but the possibility was high as a alternative for Yacto in a view of managing cost down.
