An important factor in the production of organic ginseng is the control of Alternaria blight and anthracnose, which mostly affect the leaves in the summer. We compared the effects of a lime-bordeaux mixture (LBM) and agricultural chemicals on the growth characteristics and ginsenoside content in 4-year-old ginseng plants when they were sprayed at 15-day intervals from mid-June to the end of September. The increases in leaf length, and survive-leaf ratio in plants sprayed with LBM were greater than the increases of the control plants, but less than those of agricultural chemicals treatment. The root weight per plant in the plants sprayed with LBM increased more distinctly than that in the control plants, while it was significantly lower than that in plants sprayed with agricultural chemicals. The root yield in plants sprayed with LBM increased by 21% compared to the root yield in the control plants, but decreased by 7% compared to that in plants sprayed with agricultural chemicals because of the decreases in leaf area and survive-leaf ratio. Spraying of LBM had a significant effect on the ginsenoside contents. The total ginsenoside content was highest in the control plants and lowest in the plants sprayed with agricultural chemicals and total ginsenoside contents was great relative to survive-leaf ratio and root weight.

향신료(香辛料) 및 고소득 작물로 개발가능성이 있는 고추냉이의 번식방법(繁殖方法)에 따른 성분(成分)을 비교(比較)하여 고추냉이 품질평가 및 우수 품종육성의 기초자료(基礎資料)로 제공(提供)하고자 지폐산(脂肺酸), 아미노산 및 유기산 함양(有機酸 含量) 및 조성(組成)을 조사한 결과(結果)를 (요약)要約하면 다음과 같다. 1. 총지방산 함량 및 지방산조성은 번식방법간에 차이가 없었으나 잎의 지방산함량이 다른 부위보다 높았고, 지방산조성은 부위와 관계없이 linolenic acid 함량이 가장 높았고 그 다음이 Palmitic acid, oleic acid, linoleic acid순이었으며 그 외에 lauric acid, myristic acid, palmitoleic acid, stearic acid, arachidonic acid 소량 함유되어 있었다. 2. 총아미노산 함량은 번식방법 비슷하였으나 부위별로는 잎, 근경, 줄기, 화경순으로 높았고, 아미노산조성은 번식방법에 관계없이 각 부위 모두 glutamic acid (331~1568mg), asparatic acid (346~1380mg), arginine (84~724mg), leucine (49~1264mg)의 함량이 많았다. 3. 유기산 조성은 번식방법에 관계없이 비슷하였며 부위에 관계없이 acetic acid (60.0~78.2)가 가장 함량이 많았고 그 다음은 succinic acid (9.9~32.0), malic acid (2.9~7.9%)로 함량이 많았다.
