To evaluate the biological effects of boxthorn (Lycium chinense Mill.) extracts on the immune response systems, the mitogenic effects were tested by LPS (lipopolysaccharide) and Con A (concanavalin A) using water extracts from various parts of Lycium chinense Mill. The proliferation of B-lymphocytes which were activated by the mitogen, LPS, was markedly increased in the concentration of 0.1mg/ml to 0.5mg/ml, but inhibited in more than 0.5mg/ml. It increased only proliferation of B-lymphocytes but not that of T-lymphocytes by Con A. There was no difference between boxthorn species in immune response. Water extracts of various parts in boxthorn enhanced the humoral immune response which was related to B-lymphocytes.

Jo, Hyeong-Chan ; Han, Kwang-Soo ; An, Eun-Yong ;
Korean Journal of Medicinal Crop Science, volume 8, issue 4, 2000, Pages 304~311
This study was conducted to investigate the ratio and number of the Rhus javanica gall formed by chinese sumac aphid, Scheleechtendalia chinensis, in several different conditions in which R. javanica lives. The density of 11 to 15-year-old R. javanica was more higher and the number of galls was also higher than 1 to 5- or over 16-year-old one at these sites. The formed gall according to four directions such as the East, West, South and North was founded the highest at the East and followed South, North, and West order. The formative rate of R. javanica gall did not differ in the mixture forest, and in the habitat having a heap of a little stone and mosses near a valley was better than in the site of road perimeter. Through an index of the gall diameter and the number of chinese sumac aphid, we evaluated the gall processing and development formed by the aphid. As the density of aphids increase, the size of the gall was also more plumped. The part of phyllotaxy of R. javanica gall in leaf and pinnate of was increased in the middle and upper part of terminal leaflet and leaflet was more occupied than wing. R. javanica which did not form a gall in natural environmental, formed gall by a artificial inoculation of S. chinensis. Some gall disappeared during a gall development from various environmental conditions.

To obtain the basic information for commercial process and high quality production of Saururus chinensis, useful components were determined at different growth stages and organs. The contents of quercetin, quercitrin and tannin at different growth stages were decreased before flowering time but slightly increased after flowering. The contents of quercetin, quercitrin and tannin collected on July 26 were 5.72, 5.45g/kg and 1.5%, respectively. The contents of quercetin, quercitrin and tannin were the highest in white leaf, leaf and flower, respectively.

This experiment was carried out to determine the effects of
treatment (concentration: period) to rhizomes before planting on their growth, morphology and yield.
treatment increased the number of shoots, leaves or latent buds, plant height, and leaf length per plant compared with non-treatment. The best treatment concentrations were 50 ppm in stem per plant, 100 ppm in latent bud and rhizome fresh weight per plant and 250 ppm in shoot fresh weight per plant. The number of leaves and roots per plant, plant height and fresh weights of shoot and root were the greatest in one day imbibition of
. Numbers of stems and latent buds per plant and rhizome fresh weight, however, were the highest in two day imbibition. In addition, the most rhizomes per land unit were produced in one day imbibition treatment of 100 ppm

Korean Journal of Medicinal Crop Science, volume 8, issue 4, 2000, Pages 327~333
This study was carried out to obtain the basic information for effective conservation and cultivation of Atractylodes japonica Koidz. The soil texture was sandy loam with low pH and high organic matter content compared to general cultivative land. Aerial part growth such as plant height, number of leaf, leaf length and leaf width was the highest in Tongyong indigenous species, but fresh rhizome weight was the highest in Pyongchang. Frequency of light penetration rate was high at
of full sun-light, but growth was better in high light penetration rate. The correlation between growth characteristics and habitat environment were investigated in 59 districts. Correation among growth characteristics in habitat, fresh rhizome weight was significant with plant height, number of leaf and stem diameter.

This study was conducted to determine the effects and optimum concentrantion of chemical mutagens, colchicine, EMS (ethyl methan sulfonate), MNU (1-methyl-3-1-nitrosoguanidinenitro), sodium azide
for induction of mutant plants. In order to induce the mutants of Dianthus superbus L, immature seed were pre-soaked in the warter adding each mutagens and concentration of EMS, colchicine, MNU, and sodium azide
. Comparision of morphological characteristic and seed germination in each mutant plants differed depending on mutagen sources and their concentrations. When 0.2% EMS were treated on seed, germination decreased to 12% while untreated control was germinated 76.6% for twenty days. Treatments of colchicine appeared higher germination than other mutagen but not survived. The survival rate was extremely decreased in MNU treatment at 0.5mM and chlorophyll-mutant plantlets were obtained by sodium azide treatment at 0.2mM. Chlorophyll mutants were produced by pre-soaking the immature seed of Dianthus superbus L. with mutagen, sodium azide. The control plants appeared normal green leaf color, while mutant plant after mutagenic treatment of immature seed results in yellow-green stripes and albino in normal green leaf tissue. RAPD was carried out to check the genetic modification of regenerated plants by mutagen treatments at 0.2mM sodium azide. Three polymorphic DNA fragments out of thirty-seven obtained by RAPDs were observed in regenerated plants using five decamer primers.

Korean Journal of Medicinal Crop Science, volume 8, issue 4, 2000, Pages 351~361
The juice extract of Rehmannia glutinosa Liboschitz was used to improve the productivity of ethanol in alcohol fermentation process using a 5 L fermentor under batch and fed-batch cultivations. For batch cultivation, both cell density and ethanol production were increased as the extract of R. glutinosa was increased, showing 11.8 (g/L) of maximum cell density and 0.092 (% /hr) of maximum alcohol productivity in adding 30% (v/v) of the extract. However, in adding more than 40% of the extract both cell growth and ethanol production were dropped. The cell growth was severely inhibited in 50% addition. It was found that fed-batch cultivation in adding 30% of the extract of R. glutinosa was an effective process than batch cultivation, yielding up to 30% cell growth and ethanol production. This ethanol productivity was also 30-40% higher than that obtained from a conventional alcohol fermentation. It can tell that dried R. glutinosa Liboschitz is to be used for both enhancing the yield of alcohol fermentation and utilizing biologically active substances possibly transported from R. glutinosa Liboschitz into fermented broth.

Cho, Ji-Hyoung ; Lee, Seong-Phil ; Oh, Sei-Myoung ;
Korean Journal of Medicinal Crop Science, volume 8, issue 4, 2000, Pages 362~372
This study was conducted to obtain the basic information on the production of high yield and qualitied yam in Andong, major yam-producing district, in Kyongbuk province, using three major Yam cultivars, such as Danma, Jangma and Alata (round type). Alata showed the longest tuber width while Jangma showed the longest tube length. Danma showed the highest tube yield at 2,123 kg/10a. Tubes of Alata had higher dry ratio than those of other cultivars, suggesting that Alata could be used as good processing materials. Characteristics of top parts, such as vine length, leaf number, and lateral vine number showed typical sigmoid curves. Tuber characteristics such as length, width and fresh weight of tuber were linearly increased as the growth period was progressed. Relative growth rate (RGR) for new tuber and stem reached the highest value at 86 DAT (days after transplanting). There were similar tendencies among the cultivars in net assimilation rate (NAR). The highest crop growth rate (CGR) was appeared at 156 DAT regardless of cultivars. In the changes of leaf area ratio (LAR), there were significant differences among three cultivars. LAR were decreased at 86, 106 and 136 DAT for Alata, Danma and Jangma, respectively. However, specific leaf weight (SLW) was greatly increased at 176 DAT, and leaf area index (LAI) was decreased at 156 DAT in all cultivars.

This study was conducted to investigate the sulfur effects on the yield of safflower (Carthamus tinctorius L.) and the chemical properties of soil after sulfur treatment. Sulfur application was conducted with two chemical forms of sulfur powder and potassium sulfate. Sulfur powder was applied to the soil with levels of 0, 10, 20, 40 kg/10a and potassium sulfate was applied to the soil with levels of 10, 20 kg/10a as sulfur content. After sulfur application in soils, pH and available
content of soils tend to decrease after experiment, whereas the contents of
and active Fe increased in soils. By the application of sulfur, the yields of safflower seed were increased by about
percent compared to the control. It is apparent that seed yield and plant growth of safflower were increased by the sulfur application.
