To evaluate the intraspecific variations among the Kasiogalpi(Eleutherococcus senticosus Max.) collections. randomly amplified DNA polymorphisms were examined. Twenty primers from 90 primers applied were selected. The range of polymorphism was
in 113 randomly and specifically amplified DNA fragments. Collections were divided into two major groups at the similarity coefficient value of 0.65. A considerable degree of genetic diversity was also detected among plants within the same collections. Deokyu (1, 2, 3, 4, 6), Bukhaedo (7, 8) and Odae (9, 10) col1ections showed higher degree of genetic similarity with a value of
, while Deokyu 5 showed much lower genetic similarity than other col1ections.

This study was conducted to determine the effect of seminal sections of tuber and staking methods on growth and yield of a chinese yam (Dioscorea batatas Decne). Tuber was divided into top head, head, median and tail which were used as seminal sections of tuber. The emergence of shoots was delayed in median and tail sections by 15 days as compared with top head and head sections. Sections from head and tail exhibited yield increase as high as 16 and 15%, respectively, compared to top head sections. Although flowering and bubil setting occurred almost at the same time in all staking methods, fresh weight of stem and leaves was higher in
, I-type stake supporting net than in the conventional stake. In the cultivar, 'Dan-ma', tuber yield didn't show a meaningful increase statistically by all staking methods. But
and I-type stake supporting net increased the yield of the cultivar, 'Jang-ma', as high as 11 and 8%, respectively, compared to conventional stake. Also I-type stake was ideal supportor of net, considering the cost of management.

This experiment was conducted to investigate processing method and usage of dried yam, "Sanyak". Jujube showed the higher value in extract, brix and extract content compared with Danggui and Sanyak. Mixing of Sanyak with Jujube and Danggui was proper to raise extract and taste. Brix and extract content was
and 1.80% higher, respectively, in 12 hours of extraction than in 8 hours of extraction. The apt mixing ratio was 3 : 4 : 3 (Sanyak : Danggui : Jujube). By adding 70% of glucose and 10% of lactose to 20% of extract, good viscosity and appearance of paste were obtained. 1.5mm of granule thickness was proper in phase of manufacturing, drying and shaping.

Cha, Bae-Cheon ; Lee, Sung-Bae ;
Korean Journal of Medicinal Crop Science, volume 6, issue 3, 1998, Pages 181~187
This study was carried out to investigate the antioxidative activities of medicinal plants. Through the examination of methanol extracts from 30 species for radical scavenging effects using DPPH method, the extracts from Rhus javanica Linne, Smilax china Linne and Polygonum cuspidatum Siebold et Zucarinii showed strong antioxidative activity. Because of its highest antioxidative activity among 30 medicinal plants, radical scavenging effects of 4 different extract compartments (n- Hexane, EtOAc, BuOH and
extracts) from Galla Rhois MeOH extract of Rhus javanica Linne were examined by DPPH method and antioxidant effects on the 4 different extract compartments were tested by Ferric-Thiocyanate method. Antioxidative activities of n- Hexane, EtOAc and BuOH extracts were similar or even higher than that of natural (tocopherol) or synthetic antioxidants (BHA), suggesting that major fractions for the antioxidative activity of Rhus javanica Linne were the n- Hexane, EtOAc and BuOH extract compartments.

The correlations between growth charateristics and root yield were investigated in 74 peony lines collected from chief producing place in Korea. Among these peony lines, single flower type was 61% and the rest were double type. And pink flower was in majority. Stem length, stem diameter and number of stem per plant were
, respectively. Generally, disease tolerance and root yield were better in single flower type peonies than double type. Among single flower type peonies, the correlation coefficients between each characteristics and root yield were as follows : number of stem
, number of roots
, stem length
, root diameter
and root length
. Correlation between root yield and paeoniflorin content was highly significant
among single flower type peonies and significant
among double flower type peonies. Correlation between stem diameter and root yield was not significant (0.066).

This experiment was carried out to determine the proper time for flower bud removing to improve growth, yield and paeoniflorin content of root in peony(Paeonia lactiflora Pallas). The flower buds removement caused short stem length by
compared with control, but number of stem and stem diameter were similar to that of control. The number of root, fresh root weight and paeoniflorin content in peony increased when their flower buds were removed at earlier stages. The root dry weight was highest of 1.647kg/10a, and increased by 27% compared with control when their flower buds were removed at early stage (bud diameter was less than 10mm). The root dry weight increased by 13% and 10%, respectively. when their flower buds were removed prior to flowering and at flowering stage. Paeoniflorin content in leaf was higher than that in stem, and was higher at early stage. Leaf and stem showed higher paeonif1orin content when their flower buds were removed.

This experiment was conducted to determine the effect of different size of divided crowns used as planting material on the growth characteristics, yield and quality of Paeania lactiflora Pallas (P. lactiflora Pallas). The ratio of sprouting, rooting, and growth of above-ground parts increased with the increase of crown size. The root yields of under-ground parts from different size of divided crown were 2,674kg/10a for large size and 2,304kg/10a for medium size and the yield index was improved by 39% and 30%, respectively, compared to 1,921kg/10a in small size. Commodity ratio of roots over 10mm in diameter were higher for large and medium size crown: index increased by 26 % and 11 %, respectively, compared to 1,406kg/10a in small size. Income analyzed by crown size was \ 1,133,000 per 10a at the use of small crown size but income were increased 25 % and 48 %, respectively. by using medium and large size crown as compared with small crown.

Antiinflammatory and antioxidative effects of mulberry fruit were investigated by using bioassay screening system. The extract of muberry fruits showed inhibitory effect in phospholipase
activity and cyclooxygenase II activity. Among nine varieties of mulberry tree, the antiinflammatory activities of the Shingwangppong, Ficus, Cheongilppong and Keomseolppong were higher than that of the other varieties. Also, antioxidative activity of mulberry fruit was examined by DPPH free radical scavenging method. The radical scavenging activity of the mulberry fruit decreased as following order : Shingwangppong > Keomseolppong > tetraploid Ficus> diploid Ficus.

Solomon's seal (Polygonatum odoratum) was traditionally propagated by its rhizomes but seed propagation has not been practiced due to their dormancy and high price. To improve the seedling production through seed pretreatments, the experiment was conducted to determine the effect of seedcoat softening and seed prechilling on seed germination and bulbil formation of the seal. The prechilling was done for 4 to 16 weeks at
and the softening was forced with 10% KOH for 40 minutes. Seed germination, bulbil formation and length, no. of root and root length were measured at 6 and 12 weeks after sowing. Seed germination and bulbil formation were greater at 8 to 12 week prechilling than at shorter or longer treatment when only the prechilling was enforced. Prechilling had greater effect compared to seed coat softening. In addition, the softening treatment before prechilling showed higher germination and bulbil formation compared to single treatment of them. The softening treatment prior to prechilling was better than the reverse treatment in number of root except the above two characters. Duration of prechilling treatment was able to be shortened below 8 weeks when the softening treatment was applied before prechilling.

Choi, Byoung-Ryourl ; Park, Kyeong-Yeol ;
Korean Journal of Medicinal Crop Science, volume 6, issue 3, 1998, Pages 216~220
The objectives of this study were to evaluate the effects of some seed pretreatments on seed germination, emergence, growth and yield of Bupleurum falcatum L. Seed treatments included stratification in open-field during winter, washing with running water, low temperature storage, soaking into
solution, and scarification. Germination increased 15% by stratification and 9% by washing treatment compared to non-treatment, control. It was suggested that washing treatment leached inhibiting substance, while stratification treatment leached inhibiting substance and promoted growth of immatured embryo. In the field mulched with rice straw, stratification and washing treatments were effective to shorten days to emergence by 31 and 21 days and to increase emergence rate by 7 and 5 %, respectively, compared with control. By these two treatments, root growth was improved, the number of harvested plants was increased considerably and dry root yield per ha were increased by 29 and 22 %, respectively, compared with control.

This study was conducted to develop labor-saving cultural techniques for weed control using herbicides in Rehmannia glutinosa and Astragalus membranaceus, Napropamide, linuron(preemergence) and paraquat (postemergence) showed significant herbicidal effects. At the same time they did not turn out to be harmful to the growth of Rehmannia glutinosa. The yield of Rehmannia, glutinosa treated with paraquat was higher than that of the untreated. Napropamide showed significant herbicidal effect without harmful effects to the growth of Astragalus membranaceus. Etha1flura1in and metolachlor, however, were s1ightly harmful. The yield of Astragalus membranaceus was highest with napropamide.

To analyse the management and production of medicinal crops in Uisong region, cultural conditions and standard income of 147 farms were investigated. Location quotient of medicinal crops cultivated was high as following order ; Paeonia lactiflora > Cornus ofidnalis> Bupleurm falcatum > Anemarhena asphodeloides > Rehmannia glutinosa > Eucommia ulmoides > Paeonia suffruticosa > Angelica dahurica. The average cultivated area per farm was 1.92ha : 1.35ha of upland field, 0.56ha of paddy field. Distribution of agricultural land in each farm was average 10.2 fields in 3.1 locations. Ratio of labor input in the medicinal plant sector was 31.1 %. The number of medicinal crops cultivated was 36 species among 147 farms and 2.4 species per farm. Among the cultivated medicinal plant, peony (Paeonia lactiflora) was the most popular medicinal plant, which was cultivated in 30.72ha of 85 farms. Income from medicinal plants was high in order of Carthamus tinctorius, Polygonatum stenophyllum, Angelica genuilexa. Medicinal crops should be selected based on farm condition, risk level and price settlement in order to maximize productivity and income.
