Lee, Sung-Woo ; Choi, Kyong-Gu ; Park, Jang-Whan ; Kim, Seok-Dong ;
Korean Journal of Medicinal Crop Science, volume 6, issue 1, 1998, Pages 1~5
We studied about the changes of Allylisothiocyanate (allyINCS) content in rhizome by growth period or season and the effect of foliar application of fertilizer on allylNCS content in Wasabia japonica. AllylNCS content in rhizome of Wasabia japonica was changed according to growth period or season and it was decreased suddenly in May, the last stage of flowering. Foliar application of 1 % urea increased rhizome weight, but had no effect on allylNCS content in rhizome. Total three times foliar applications of 1 % potassium sulfate from Feb. to April increased rhizome weight by 44% and allylNCS content by 38% compared with control and potassium sulfate was more effective than ammonium sulfate. Even though the use of 1 % urea and 1 % ammonium sulfate caused growth disorder due to high concentration, rhizome weight was similar to the control and allylNCS content of rhizome increased by 47% more than control.

Vitamin contents in different plant parts and harvesting time of Rosa davurica Pall. were determined to examine their applicability for a new medicinal supply. Among plant parts analysed, leaf contained the highest ascorbic acid concent of 1973.9 mg/100g. Fruit contained ascorbic acid (714.6mg/100g) 2. 7 times less than leaf. Vitamin contents in leaf parts also differed depending on harvesting time. Vitamin content in leaves harvested in November was much higher than that in September. Spectrophotometric analysis of total
in leaf showed higher contents than that in fruit.

This experiment was conducted to investigate the soil temperature. the characteristics of seedling growth and drought resistance of Job's tears under different seeding depth. The changes of soil temperature were similar to the patterns of atmosphere temperature. and the minimum and maximum temperature of the day were at 08: 00 and 16: 00 hours, respectively, and this was 1 hour late compared to the atmospheric temperature. In mean temperature under different soil depth, 3cm and 4cm soil depth were the same as
which was higher than that at 1cm and 2cm soil depth. Percentage of emergence was 81.2% at 4cm soil depth in Yulmoo 1 ho and 88.0% at 3cm soil depth in Yunchon 9 ho, respectively. Days to emergence after seeding was shortest at 1cm seeding depth as about 9 days and was 2 to 3 days later at other soil depth of 2, 3, 4cm compared to 1cm soil depth plot. Plant height and dry matter weight was highest at 3cm soil depth in Yulmoo 1 ho and at 4cm soil depth in Yunchon 9 ho. In the drought conditions, percent of survived plant was highest at 4cm soil depth plot of both varieties as 51.3% and 60.0%, respectively. In the drought conditions, soil depth was positively correlated with % of emergence, days to emergence after seeding, plant height, and dry matter weight per plant.

This experiment was conducted to find the most effective organic matters to improve the contents of aromatics and essential oils in root of Anthriscus sylvestylis. Growth of top part was promoted by application of chicken dung with saw dust. The contents of crude protein, fat and fiber were also increased by chicken dung with saw dust. Essential oil content was highest as 0.82% when plants were treated by chicken dung with saw dust. The optimum organic matter showing high yield was chicken dung with saw dust as 276kg per 10a. Twenty two aromatic constituents were identified from root of Anthriscus sylvestylis regardless of organic matter kinds. In particular, aromatic constituents such as sabinene and carboxaldehyde were highest at the application of chicken dung with saw dust as 16.9 and 163.4 % area, respectively.

Lee, Seong-Phil ; Kim, Sang-Kuk ; Choi, Boo-Sull ; Lee, Sang-Chul ; Yeo, Soo-Kab ;
Korean Journal of Medicinal Crop Science, volume 6, issue 1, 1998, Pages 21~27
This experiment was conducted to increase aromatics in roots of Condonopsis lanceolata by applications of organic matters. Fresh root wt. was increased by conifer/moss application to 79.1g per plant. Crude protein content was also higher at rice straw application than native soil application and crude saponin content was increased by conifer/moss application, but contents of crude fat, fiber and ash were not different in all treatments. Although contents of K, Ca, and Mg were increased by rice straw application, Fe, Mn, Zn, Na and Cu were not significantly different in all treatments, The highest free amino acid was arginine, it was increased by the application of fallen leaves and the highest yield (0,008%) of essential oils was obtained by conifer/moss application. As a result, to produce C. lanceolata plant showing higher quality and aromatic essential oils, it was considered that the most effective organic matter showing high yield and higher aromatic constituents was conifer/moss application of over 3M/T per 10a.

Browning index rised rapidly within 15 hrs to 83% of total browning in Jang - ma (Dioscorea batatas Decne) tissues at
while 37% in Dan - ma. Therefore, the degree of browning process of Jang - ma was faster than that of Dan - ma. Browning in Jang - ma was inhibited by treatments of NaCl which showed 48 and 39% inhibition, respectively, after 48 hrs of incubation. Also the treatment of
heating showed excellent inhibition within 24 hrs. In the case of Dan - ma, browning process was inhibited by treatments of 1 and 0.5M NaCl and
heating, which showed 43, 26 and 23% inhibition, respectively, after 48 hrs of incubation.

This experiment was carried out to gather basic information for improvement of peeling methods in peony (Paeonia lactiflora) roots which have been used for medicinal resources in Korea. Drying time required was shortened in thin root. Optimum drying time after machine peeling appeared to be 20 hrs in 5 to 10mm of root diameter, 39 hrs in 10 to 15mm, 48 hrs in 15 to 20mm, 56 hrs in more than 20mm, but those of unpeeled roots took 11 hrs in 5mm of root diameter and 4 hrs in exposed parent material. Paeoniflorin content in dried roots after peeling was lower than that of unpeeled root. Paeoniflorin content in root below 5mm in diameter was highest (6.15 %) and that was decreased in the increased root diameter up to 20mm, but it was slightly increased in root greater than 20mm in diameter.

The experiment was carried out to investigate weed occurrence in peony field. The number of weeds was Compositate 9 species, Gramineae 4 species, Craciferae 3 species, Eugarviaceae, Polygonaceae and Scrophularilaceae 2 species, respectively. Weeds classified by life cycle were annual weed 19 species (57.6%), biennial weed 8 species (24.2%), and perennial weed 6 species (18.2%). Weed species and dominance rate by morphological characteristics were grass weed 4 species (12.1%), broad leaf weed 25 species (84.8%), and sedge weed 1 species (3.1 %) . Major dominant weeds were Capsella bursa-pastoris, Chemopodium album var. centrorubrum and Equisetum arvense in late April, and Digitaria sanguinalis, Erigeron canadensis and Echinochlor crus-galli in late June, and Digitaria sanguinalis, Erigeron canadensis and Echinochlor crus-galli in middle August.

This study was carried out to evaluate environmental and ecological characteristics of natural habitat for cultivation of Epimedium koreanum. Habitat of E. koreanum was the slope foot of mountain descending gradually toward mostly northwest from top of mountain with slope of
and the altitude ranged from 60 to 400m above the sea level. Some physiochemical characteristics of habitat soil were as follows: pH,
, organic matters content,
and cation exchange capacity,
soil, respectively. Habitats were shaded by deciduous broad-leaved tree mainly, and compared with those of naked area, relative photon flux density was
and relative luminance was
due to shading. Air temperature of habitat under shade was
lower than that of naked area. Habitat soil temperature was lower than that of naked area but temperature range was smaller than that of naked area. E. koreanum plants were growing with semishading plants under shade of tree leaf. From investigation of natural characteristics of habitat, it was concluded that E. koreanum plant would grow at place with a little change in temperature and moisture of soil which was caused by shading and mulching with litterfall of broad-leaved tree.

Angelica gigas, Astragalus membranaceus and Ligusticum chuanxiong have been grown for a long time in Korea as medicinal crops with underground parts. Its harvesting method has been depended entirely on manual labor. Therefore, harvesting involved much work. This study was to determine an effective mechanized harvesting method for underground parts of some medicinal crops by several machines. Labor time was decreased by 61 percent in Angelica gigas and by 70 percent in Astragalus membranaceus by the use of poclain harvester, however, in Ligusticum chuanxiong was decreased 68 percent by multi - root harvester compared with conventional system (manual harvest). The poclain harvester was suitable for harvesting in Angelica gigas and Astragalus membranaceus plots, but multi - root harvester was not satisfactory. Multi - root harvester appeared to be appropriate harvester for Ligusticum chuanxing.

There was no significant difference in length and width of leaf and number of leaves per plant between tissue-cultured plants and conventionally propagated ones but chlorophyll content increased in tissue-cultured ones. Percent of sprouting from planted root segments significantly increased in tissue-cultured plants, resulting in yield increase of more than 200% per 10a. Root thickness of tissue-cultured plants at the time of planting influenced percent of sprouting and yield. Plants with root diameter ranging from 3 to 6mm gave good yield. When virus infection was monitored with N. tabacum and C. amaranticolor as indicator plants, 100% infection occurred in vegetatively propagated plants and introduced plants from China. whereas plants obtained from apical meristem showed 0% and 40% to 45% infection in vitro plantlets and 1 year old plants in vivo, respectively. Tobamovirus and unidentified virus particles were detected in electron microscopy.
