Korean Journal of Medicinal Crop Science, volume 4, issue 1, 1996, Pages 7~11
This study was conducted to know the effects of light intensity and temperature on growth of V. fauriei plants. Photosynthesis of V. fauriei had highly significant relations to light intensity and temperature in a quadratic regression model, from which the optimum light intensity and temperature for the plant growth were estimated to be 40,000lux and
Root was produced less by shading at Jinbu where is located in alpine region, but root yield is increased by shading at Umsong where is located in plane region. Roots were produced more in Jinbu than in Umsong. A highly significant quadratic regression was noted between temperature and leaf width or root weight of V. fauriei. It was estimated from the regression equation that the optimum temperature for root growth was

This study was investigated to improve the rate of the seed germination of Wasabia japonica with
and BAP. The germination rate was 36% with 100ppm
only and 32% with 10ppm BAP only, while that was 65% with combination of 100ppm
and 10ppm BAP compared to that of 7.5% in control. This results show us that the most effect of germination rate was with 100ppm
and 10ppm BAP. Mutagenesis was induced with mutagen, EMS and colchicine. Before the germination, the survival rate was 62% with 0.5% colchicine compared to that of 7% in control. After the germination, the 85% of developed seed was alive with treatment of 0.5% colchicine and 55% of those was alive with 0.06% EMS compared to that of 8% in control. We analyzed the karyotype and isozyme pattern of Wasabia japonica induced with colchicine and EMS. The tetratype of Wasabia japonica was observed from Wasabia japonica treated with 0.5% colchicine. whereas it was not observed with 0.06% EMS. The peroxidase pattern of colchicine treated Wasabia japonica was different from nontreatment. but that of EMS treated Wasabia japonica was the same with normal one.

The crop rotation of rice and ginseng in paddy field has very important meaning because up-land field suitable for ginseng cultivation is now being insufficient day by day in main ginseng production area. This studies were conducted to define basic problems related to ginseng cultivation and replanting in paddy field. In Keumsan district, the most serious problem on ginseng cultivation in paddy field was excess of mineral salts left behind in the soil of rice cultivation. The amounts of organic matters, CEC and the mineral elements including potassium were higher in the soil of paddy ginseng field compared to those of upland. Plant growth of 3 and 4 year old ginseng and root yield of four year old ginseng cultivated in paddy field of 1st and replanting were not decreased compared to those of 1st - planting of up-land field, but those were significantly decreased in replanted compared to those of first planted upland field. Crop rotation with ginseng and rice in paddy field seemed to be a good way to avoid hazards of continuous cropping of ginseng with it's outyield of root and less infection of diseases. Amounts of crude saponin and ginsenosides of ginseng cultivated in paddy field were not differ from those of upland field.

Korean Journal of Medicinal Crop Science, volume 4, issue 1, 1996, Pages 27~30
This study was conducted to obtain basic information on growth characteristics and major components of three Korean endemic resource plant species, Artemisia sp., Gynostemma pentaphyllum Makino and Humulus japonicus S. et Z. , growing in different areas in Korea. Three geographical types of artemisia, namely Pangssuk, Ongjinssuk and Yakssuk which were collect in Suwon, Ongjin and Eumsong, respectively were compared in yield, and Pangssuk artemisia was higher in yield than the others. However, essential oil content was the highest in Yakssuk artemisia. Dry weight of areal parts of G. pentaphyllum was higher in the cultural method with props for tendril growth than in the conventional cultural method without props. Rutin was detected in areal parts of G. pentaphyllum. Dry weight of areal parts of H. japonicus collected at the Kyeryong mountain in Chungnam province was higher than that collected in Eumsong. A phenolic compound isoquercitrin was detected in areal parts of H. japonicus.

Korean Journal of Medicinal Crop Science, volume 4, issue 1, 1996, Pages 31~37
This study was conducted to know the odor characteristics and compounds in neutral, acidic and basic fraction from the essential oil of Valerliana fauriei root. Among the fraction from the essential oil of V. fauriei root, the content of neutral fraction was 92%, that of the acidic fraction, 6%, and that of basic and phenolic fractions, less than 1%, respectively. The neutral fraction was characterized by sweet-balsamic, woody, musky and medicinal odor. The acidic fraction had sweat-socks, valeric-like and cheese-like odor characters. The netural fraction of essential oil was fractionated by solvents with different polarities, resulting in 44% of ethyl ether fraction, 34% of pentane-ethyl ether fraction, 11% of pentane fraction and 11% of methanol fraction. The ethyl ether fraction was characterized by woody and medicinal odor and the pentane-ethyl ether fraction, by sweet-balsamic, woody and herb-like odor. The fractions were fractionated again by different solvents, and 12 chemical components including valeranone, 26 components including bornyl acetate, and 43 components including camphene were identified in the ethyl ether fraction, the pentane - ethyl ether fraction, and pentane fraction, respectively. In the acidic fraction, n-butanoic acid and other 44 components were identified, among which the most abundant ones were 3-methyl butanoic acid(42.1%), dimethoxy-2-propanoic acid(11.5%), and 5-ethyldihydro-2H-furanone(5.7%).
Effects of Flower Color and Culture Periods on the Growth Characteristics and Quality Differences in Chinese bellflower (Platycodon grandiflorum)
Park, Suk-Keun ; Chae, Young-Am ;
Korean Journal of Medicinal Crop Science, volume 4, issue 1, 1996, Pages 38~46
These studies were conducted to know the any differences in growth characteristics and root quality due to flower color and culture periods in Chinese bellflower. White flowered lines had tendency of increasing in growth characters such as stem numbers, capsule numbers and seed yield per plant, plant height, and root characters such as root weight, root length and root diameter even though statistically not significant. No differences were observed in saponin and essential oil contents between them. Three years old plants had more stems and capsules per plants, root weight and root length than two years old plants while no difference in saponin and essential oil contents between them. Saponin content was gradually decreased while essential oil content was clearly lowed in the roots from plants cultured more than 3 years even though no differences in stem and capsule numbers per plant and plant height.

Korean Journal of Medicinal Crop Science, volume 4, issue 1, 1996, Pages 52~57
This study was carried out to compare isozyme band pattern, growth characteristics and tuber yield of Dioscorea batatas to get basic information for varietal classification. It could be identify clearly by protein and esterase band pattern of leaf, petiole and stem tissue in three cultivar but with peroxidase band it was difficult to identify because of similar pattern in leaf and petiole tissue. Three cultivars has different leaf shape as Dan-ma and Jang-ma were lanceolate, Sukunea was long-heart shape in upper part of plants. In phyllotaxis, Dan-ma and Jang-ma shows alternate and opposite but Suwon 2 shows opposite in upper parts of stem. Root length shows significant difference from 9.7cm to 51cm respectively as 30cm, 51cm and 9.7cm in Dan-ma, Jang-ma and Sukunea. Tuber yield of three cultivars were 27.5M/T in Dan-ma, 22.8M/T in Jang-ma and 22.8M/T/ha in Sukunea.

Stem length, main root length and main root diameter showed rapid increasement in two-years-old and three-years-old peony. And there after, the increasement was almost finished. Occurrence of disease was increasing every cultivated year, especially the development of leaf spot was most serious. In propagation by root dividing method, the radix yield (kg/10a) was increasing every cultivated year. However, the difference of radix yield at four and five-years-old peony were not significant. The radix yield of four-years-old peony was higher 26% than three-years-old one. As cultivated year goes by, content of paeoniflorin was increasing then the content was highest at four-years-old peony (4.06%). In 1995, the content, had no certain tendency, was highest at three-years-old peony (3.14%). At hot air drying, browing of peony radix was increasing every cultivated year. If we consider radix yield and color, three-years-old peony was proper object of harvesting.

Korean Journal of Medicinal Crop Science, volume 4, issue 1, 1996, Pages 74~77
This experiment was conducted to evaluated the effect of CM (plant growth regulator) treatment on flowering, pod maturing and root yield components of Astragalus membramaceus Bunge. Three dilution rates (60, 70 and 80 times) were sprayed at
leave stage. As the results, flowering was delayed
days than August 13 of control and higher dilution rates was more effective to delay flowering. At the havesting time, be compared with non-treatment, plant height reduced
and number of matured pods were decreased
by increasing dilution rates. However, weight of dry root per plant was increased to 29% and dry root yield per 10a was increased to 28% in dilution rates 70 compared with non-treatment.

Korean Journal of Medicinal Crop Science, volume 4, issue 1, 1996, Pages 78~85
The effects of growth regulators, sucrose and gelling agents were investigated to increase the efficiency of the callus growth and plant regenerarion in tissue culture of Angelica koreana Max. The fresh weight and dry weight of subcultured callus was highest in MS medium supplemented with 1 mg/l 2,4-D. Callus growth was excellent in 2% sucrose, but it was inhibited in propotion to sucrose content. Effect of gelling agents on callus growth was highest on 1.2% agar and 0.4% Gelrite medium, respectively. The browning of callus was protected on the media supplemented with 10 mg/l ABA and 5 or 10 mg/l
. In the callus induction and growth from the peduncle of immature inflorescence, 2,4-D was more effective than NAA, and the frequency of callus induction was highest as 81.7% in 2 mg/l 2,4-D. Plant was not regenerated from the callus derived from young leaf. Somatic embryos were developed from the surface of callus drived from the peduncle of immature inflorescence in the medium containing 0.5 mg/l 2,4-D, 1 mg/l kinetin, 5 mg/l ABA and 5 mg/l
. Plants were developed from the matured somatic embryos in the medium supplemented with 0.2 mg/l 2,4-D and 1 mg/l kinetin.
