Choi,Seong-Kyu,Yum,Kyeong-Won,Chon,Sang-Uk 한국자원식물학회 2003 Plant Resources Vol.6 No.3

This study was conducted to investigate the effect of Activated charcoal (AC) for stimulating growth and productivity of Curcuma longa Linne as affected by different concentrations of AC. Growth characteristics such as plant height and leaf length were the highest with the optimum amount of activated charcoal ranged from 10 to 30%. Root growth was elongated by the addition of 30% AC with the highest rhizome length and weight.

A Study on Storage of a Major Herbal Medicine Material, Peucedani Radix

Choi,Seong-Kyu,Yun,Kyeong-Won,Kwon,Byung-Sun 한국자원식물학회 2002 Plant Resources Vol.5 No.2

To develop optimal storage method of root of Peucedani Radix, which has been grown as major cultural herbal medicine material, root of Peucedani Radix was stored for 10 months with different packing materials and sealing methods. The loss in dry weight as influenced by packing materials and sealing methods was the lowest at vacuum packing and followed by complete sealing methods with transparent polyethylene film. The ratio of root rot during the storage period was not significantly different between packing materials but was significantly different between sealing conditions. Conclusively vacuum packing and complete sealing with polyethylene film appears to be optimal for storage of Peucedani Radix.

Choi,Seong-kyu,Yun,Kyeong-Won,Chon,Sang-Uk,Seo,Young-nam 한국자원식물학회 2002 Plant Resources Vol.5 No.1

To develop an optimal storage method of root of Angelica acutiloba Radix, which has been grown as major herbal medicine material to be cultivated, root of Angelica acutiloba Radix, was stored for 10 months with different packing materials and sealing methods. The loss in dry weight as influenced by packing materials and sealing methods was the lowest at vacuum packing and followed by complete sealing methods with transparent polyethylene film. The ratio of root rot during the storage period was not significantly different between packing materials but was significantly different between sealing conditions. In conclusion, vacuum packing and complete sealing with polyethylene film appears to be most optimal for storage of Angelica acutiloba Radix.

Choi,Seong-Kyu,Yun,Kyeong-Won,Chon,Sang-Uk,Seo,Young-Nam,Seo,Kyoung-sun,Kwon,Byung-Sun 한국자원식물학회 2003 Plant Resources Vol.6 No.3

This study was conducted to produce effectively more leaves of Angelica acutiloba through year-round production system by using various mulching materials and polyethylene(PE) tunnel. Soil temperature by covering treatment was higher in PE mulching and PE tunnel than in rice straw mulching, especially showing the highest temperature in PE tunnel from April through May. Water content of soil was higher in PE mulching than in non-mulching. Leaf production of Angelica acutiloba through year-round production showed the highest in PE tunnel and root production in PE mulching. These results suggest that leaf production of Angelica acutiloba can be maximized through PE tunnel cultivation system.

This study was carried out obtain basic information for growth characteristics by different age of Dendropanax morbifera in chonnam, such as Yosu, Sunchon, Haenam, Gangjin, Wando. The pH of soil in cultivation area was 5.2 to 5.6 and organic matter was very high up to 10.6% . P205 content of soil in cultivation area was 35.3 to 42.1 mg/L, C.E.S was 13.9 to 14.4 me/100g, and moisture rate was 19.2 to 21.1 % . The flowering of Dendropanax morbifera began from 6~7 years old tree. The flowering date was at 10th of July at Wando. The growth characteristics of 12 years old tree was 929.5cm in stem height, 134.1mm in stem diameter, and 15 years old tree was 1,117.9cm in stem height, 160.8mm in stem diameter. The number of leaf was 13.9 at five years old tree, and the petioles length was 12.6 at five years old tree. Xylem sap can be had at more than 10 years old tree with good growth more than 10 em stem diameter.

최성현,김찬조,최성희,오홍록 충남대학교 농업과학연구소 1998 농업과학연구 Vol.25 No.2

To evaluate the storage characteristics of pheasant meat products, contents of aerobic, anaerobic and food poisoning bacteria as well as VBN were measured during storage at various temperatures. 1. During the storage Escherichia coli and food poisoning bacteria including Salmonella, Shigella and Staphylococcus were not detected from any of the pheasant meat products. 2. Total plate counts of aerobic and anaerobic bacteria increased with storage temperature, showing more than 10^6 CFU/g of most pheasant meat products within 5~10 days of storage at 20℃ and 30℃. However, frank sausage, loin ham, pressed ham and salad showed less than 10^5 CFU/g in 20~30 days of storage at 20℃. 3. When stored at 10℃, smoked product, electric roasted product and pressed ham showed the bacterial counts of more than 10^4 CFU/g within 10 days of storage. Frank sausage, loin ham and salad, however, showed less than 10^3 CFU/g in 10 days of storage at 10℃. 4. VBN contents of smoked product, electric roasted product and frank sausage exceeded edible limit of 20 mg%, showing more than 40 mg% and 8 mg% within 5 days and 10 days, respectively, of storage at 10℃. In contrast, loin ham, pressed ham and salad had the VBN of less than 20 mg% in 10 days of storage at 10℃. In summary, while pheasant meat products in general appear to be prone to microbial growth, loin ham and salad are thought to have a longer storage period than others, showing about 10 days of preservation at 10℃. Products other than loin ham and salad are suggested to be stored frozen or refrigerated at below 10℃.

Choi,Seong-Kyu,Yun,Kyeong-won,Chon,Sang-Uk,Lee,Jong-Ill,Seo,Young-Nam,Seo,Kyoung-Sun,Choi,Kyeong-Ju 한국자원식물학회 2004 Plant Resources Vol.7 No.3

This study was conducted to develop effective production system in greenhouse for leaves and stems of Angelica acutiloba by using connect pots in 2003 and 2004. Seed germination rate and plant biomass of Angelica acutiloba collected in 2004 were higher than those harvested in 2003. Germination rate of Angelica acutiloba seeds collected in 2003 was 10%, while germination rate of seeds collected in 2004 was above 90%. Especially, plant growth and yield of Angelica acutiloba grown in connect pots sized with 4×4×5cm(length×width×height) were the highest. These results indicate that leaf and stem production of Angelica acutiloba can be improved by using connect pots and optimizing seed collecting time in greenhouse.
