Effect of Drying Condition on the Colors and Flavors Change of Fresh pepper
Korean Journal of Plant Resources, volume 8, issue 2, 1995, Pages 115~125
The moistures, colors and flavors of red pepper were analyzed to observe the changes of the qualities of red pepper with various conditions of drying. The moisture was 11.8%, known as optimal condition for storing red pepper, where dried at
for 36 and 48 hours. The color of red pepper air-dried at 50% for 48 hours was estimated to be the most execllent in comparison of sun drying and air drying. The optimal absorbances of hexnae extract from red pepper were examined. The ratios between the absorbances at 280nm and at the typical wavelengths of caretenoids(430nm, 450nm, 474nm) were from 2.5-3.4 and these wete also confirmed by the sight of the eye. Hexane fraction showed more peaks of flavors than benzene fraction and both of the two were silylated by with BSTFA to analyze the flavors by GC. CG profiles for the compositions of flavors in red perpper are thought to be useful for extimating the quality of favors in red pepper. Eight flavors including benzene dicarbozylic acid, were identified from red pepper and major components of them were oleic palmitic acids. Drying temperatures and times did not have effects on the changes of specific flavor components but did influenced the compositions of them in red pepper.
Pharmacognostical Studies on Ginseng Folium
Korean Journal of Plant Resources, volume 8, issue 2, 1995, Pages 127~133
Ginseng Folium has been used to cure acute gastritis, alcoholism and anemia. The morphological and anatomical characteristics of the leaf and stem of Panax ginseng C.A. Meyer cultivated in Korea for 1 to 6 years are described. It is found that the vessels increase in number and diameter, and also the vascular bundles increase in number, as the plant becomes old. The result showed that the commercial &In Sam Ip& samples on the markets of Pusan, Kumsan, Taegu and Seoul have been derived from the leaf and stem of 4 to 6 years old P. ginseng plants, most of them being 5-6 years old.

A Fundmental Study on the Medicinal Plant For Cut Plants
Korean Journal of Plant Resources, volume 8, issue 2, 1995, Pages 143~151
The development of medicinal plants for cut plants and landscape plants were conducted through the literiture survey. The results were as follows: We selected 38 species of medicinal plants including 7 medicinal woody plants for cut plant and landscape plants from 450 medicinal plants. There were 8 species of Compositae, 4 species Ranunculaceae, 3 species Rosaceae and Umbelliferae, 2 species Polygonaceae and Campanulaceae respectively. The anthesis of Cornus officinalis, Magnolia denudata, Forsythia koreana of medicinal woody plants flowering before leaf spreading come to early than the anthesis of other medicinal plants. There were 4 species(11%) over 10cm of the flower diameter, 6 species(16%) over 5cm below 10cm, 19 species(50%) over 1cm below 5cm and 9 species(24%) 1cm below. In terms of flower color, 11 species(29%) were white, 9 species(24%) yellow, 6 pecies(16%) red, 5 species(13%) violet and 3 species(8%) were blue aided violet. In terms of the flowering by month, 12 species(32%) on July, 9 species(24%) on May, 6 species(16%) on June and August respectively, and 3 species(8%) on March. The most medicinal plants were propagated by division and seeding easily, but woody medicinal plants of 7 species of this study were propagated by cutting and grafting easily. The percentage of usage of parts of medicinal plants including woody medicinal plants was that roots were 20 species(53%), flowers 6 species(16%), fruits and all part of medicinal plants were 4 species(11%), and seeds and stem including leaves 2 species(5%) respectively.

Growth Root Tuber and Economic Yields of Chinese Yam and Their Relationship as Affected by Tuber Head Origin and Fertilizer Application Method
Korean Journal of Plant Resources, volume 8, issue 2, 1995, Pages 201~207
Chinese yam (Dioscorea Opposita Thanb) has been cultivated as medicinal crop and food. The experiment was carried out to determine the effect of tuber head origin and fertilizer application method on its agronomic characters of shoot and root tuber to get some imformation on its cultivation. The tuber head cultivated were cut from normal or branched root tuber. 37-28-32-2000 : N-P-K-Humus(Kg/10a) by dispersal but 30% N reduction of Con(RN) or strip application on the two-side of hill(SRN), were applied but N and K were given by the above method with the rate of 40% in March, 30% in June and 30% in July. Agronomic characteristics related to shoot and root tuber were measured and their relationship was analyzed. Tuber head origin had no effect on emergence rate, vine length, branch and node of vine, while emergence date of the tuber head from the normal root which showed the greatest emergence rate, vine length and node in Con treatment was earlier than the others. The tuber head from the normal root, furthermore, had greater length and diameter of root tuber harvested from the field and fresh weight per plant of per 10a compared to the tuber head from the branched root, whereas in both the normal and the branched tuber head RN had the worst result in the characters related to tuber yield except tuber diameter. The tuber head from the normal root produced heavier root tuber than that from the branched tuber and SRN had the best economic yield among the application methods, which resulted from production of less branched root tubers and their rate. In both the normal and the branched tuber head, moreover, yield per plant and economic yield were positively correlated to tuber length but negatively done to number. of branch of vine.
Effect of Planting Density on Growth and Yield in Cyanachum wilfordii
Korean Journal of Plant Resources, volume 8, issue 2, 1995, Pages 209~215
This experiment was carried out to elucidate the effect of row width and hill space on growth and yield in cynanchum wilfordii on experimental fields of chungbuk Provincial Rural Development Administration. Emergence date was May 25 and had no differences between planting density. Vine length was 219cm with row 40cm, 220cm, with 50cm and 225cm with 60cm, and in hill spaces, it was 225cm with hill space 10cm, 219cm with 15cm, and 218cm with 20cm. No. of leaves was same tendencies to vine length and was more increased as the hill space was narrower. Root length was longer about 0.9cm to 1.4cm as the hill space was wider, and no. of root had no difference between planting tensity. Yield was more increased row width was wider and was decreased hill space was wider. And the profitalble planting density was row width 50cm and hill space 10cm in the cultivation cynanchum wilfordii.
