Effects of Hairy Vetch and Animal Slurry on Growth and Yield of Astragalus membranaceus Bunge
Ryoo, Jong-Won ;
Korean Journal of Medicinal Crop Science, volume 11, issue 2, 2003, Pages 83~88
This experiment was carried out to investigate the effect of the mulching of hairy vetch and pig manure on the growth, yield and crude protein contents of the mulching of hairy vetch and application of animal slurry were treated and investigated in
. At the first year of cultivation, there were no differences among the treatments in plant height, but second year the growth of plants increased and continued over long times as the hairy vetch mulched and fertilized. The length and diameter of plant root were increased in the plot of hairy vetch mulching and the application of animal slurry. At first year of cultivation, no clear difference was found for among the treatments on dry weight and dry matter ratio in roots. At second year of cultivation, they were increased at in the plot of mulching and fertilizer treatment. The appearances of weeds in the field on Astragalus membranaces were much lower on the plots of live-mulching of hairy vetch than those on the control. The yield of root was 255kg highest in the plot of mulching and animal slurry application of 2-year-old roots. The root yield of Astragalus membranaces was increased about
compared to that with control, due to supply of nutrients. During the cultivation times, organic matters and N contents in soil increased by the mulching of hairy vetch and the application of animal slurry. The concentration of K, Ca concentration in soil showed a tendency to increase.

Korean mistletoes extracts were investigated for in vitro antioxidation activity, with 1,1-diphenyl-2-picrylhydrazine(DPPH), and an inhibitory effect on oxidative DNA damage by using comet assay. The Korean mistletoes were 4 different kinds classified by their host plants (Korean Viscum sp. in Quercus acutissima Carr., Korean Viscum sp. in Castanea crenata, Korean Viscum sp. in Betula platyphylla, and Korean Viscum sp. in Salix koreensis). The samples were extracted with ethanol, and fractonationed with n-butanol, ethyl acetate, chloroform, n-hexane, and second distilled water. Among them, ethyl acetate fraction from Korean Viscum sp. in Betula platyphylla showed the strongest activities to electron donating ability on 1,1-diphenyl-2-picrylhydrazyl(DPPH) and the protective effect on oxidative DNA damage.

The purpose of this experiment is to improve the ratio of female flower in Schizandra chinensis Baillon. The experiment was carried out in two purposes. One was to understand the development stages on bud formation and determining sex after bud formation by stage. The other was to investigate characteristics of flowers forming on spring when summer pruning was taken place in different cutting part and timing in S. chinensis Baillon. The outcome was that on 7th of June the flower bud was found next to leaf primordium in branch of this year and no changes were found in shape for two weeks by 26th July. On 26th of June, an ovule that forms organ was observed and then, an ovule was found after sex was determined on 6th of July. Second experiment was carried out to find out when the sex was determined by adapting different pruning methods; cutting the branch at 6th node on June 1, June 15, and July 1; cutting the branch at 10th node on June 15, and July 1. The result was that the re-growth ratio on the branch 6th node was cut on June 1 and June 15. July 1 was 34-56% and, however, the number of setting flowers and mail flowers were fewer than the normal branches. More over, even though the re-growth ratio of branches were 34-25% when the cutting was taken place at 10th node on June 15 and July 1, the number of setting flowers and mail flowers were the same as the non treated branch. As a result, it is assumed that cutting controlling in this plant to increase the number of female flowers has no effect.

This experiment was conducted to evaluate the diversity and purity of the Korean ginseng (Panax gjnseng) lines developed by the pure line selection using RAPD markers. Four primer (OPA 19, OPM 11, URP 3 and UBC 98) out of the 48 primer tested produced band which showed within-line polymorphisms at least in one line. Within-line polymorphisms were detected in six lines by OPA 19, in four lines by URP 03, in five lines by OPM 11, and in one line by UBC 98 respectively. Five plants obtained from the commercial cultivar 'Cheonpung' were differentiated using the primers OPA 19 and OPM 11. Five plants obtained from the 'Yeonpung were differentiated using the primer OPM 11. Detection of within-line RAPD polymorphisms might be attributed to the fact that cross pollination appear in P. gjnseng and a long period of three to four years required to reach the reproductive stage thereby delay the process to homozygosity.

Kang, Young-Kil ;
Korean Journal of Medicinal Crop Science, volume 11, issue 2, 2003, Pages 109~114
To determine the optimum N rate m Jeju island for utricle and root production of Achyranthes japonica Nakai, a medicinal plant, the plants were grown at two plant densities
, two plants per hill; mall plots) at six N application rates (0, 6, 12, 18, 24, and 30 kg/10a; split plots) in 2001. There was no significant interaction between plant density and N application rate for all measured agronomic characters. Main root length and roots per hill were 5 and 52% greater, respectively, but N content of stover was lower under lower plant density compared to higher plant density. The other characters were not affected by plant density. N application rate did not significantly affect mall stem diameter, spikes per hill, spike length, utricles per spike, mall root length and diameter, and utricle N content. As N rate increased from 0 to 30 kg/10a, SPAD values and stover N content increased linearly from 35.0 to 40.5 and 1.09 to 1.38%, respectively, and plant height, branches per hill, stover, utricle and root dry matter yields, roots per hill, and top N yield increased quadratically. Spikes per hill were increased in a cubic manner with increased N application rates. N application rate for the maximum dry matter yield of utricle and root in A. japonica was estimated to be 21 kg N/10a.

Essential oils from Fennel fruit(Foeniculum vulgare Mill), Olibanum resin(Boswellia carteii Birew) and Needl Juniperus stem(Juniperus rigida Sieb.) were extracted by a supercritical fluid extraction system(SFE) and biological activity of each essential oils were observed. SFE technique was applied for the isolation and purification of nonpolar biologically active essential oils from each samples. The quantitative analysis of essential oils was carried out by gas chromatography-mass spectrometer(GC/MS). About 60% of the growth of AGS and A549 cells were inhibited by adding 1.0g/l of the crude essential oils and below 40% was observed by the control. Cytotoxicity on human normal lung cell(HEL299) was scored as
for the crude essential oils and 12% for control, respectively. It meant that the essential oils were more effective than the control in anti-mutagenecity tested by CHO V79 cells. The effect of the essential oils on the growth of nerve cells, PC12 was observed as follows: The viable cell density was about two times higher than control.

One hundred sixty species among Korean medicinal plants were tested on their antioxidative potentials. Antioxidants are useful materials which could be expected into development as food preservatives, health foods, cosmetics and drugs. Korean peninsula have many potential in antioxidant source which includes various medicinal herbs. It grounded on the fact that Korean medicinal plants have been used as folk therapy for long time and still do in oriental medicine. From the study, effective free radical scavengers compared with
were Geranium sibiricum, Geum japonicum, Geranium nepalense subsp. thunbergii and Paulownia coreana which showed
, respectively, Acer mono and 38 plants showed strong potential in inhibition rate on linoleic acid oxidation (above 90%). In conclusion, we expect that the selected medicinal plants must be more studied as antioxidant and then developed as many industrial materials.

This study was designed to investigate the effect of Korean Red ginseng(Panax ginseng C.A. Meyer) extracts on antioxidative activities in Sprague-Dawley rats. This study also evaluated the synergistic effect of Korean red ginseng(RG) extracts with Saururus chinensis(Lour.) Baill(SC). and Rubus coreanus Miq.(RC) extracts. Experimental groups were divided into supplementation type(RG extracts, RG with SC and RC extracts) and amounts of extracts. Rats were received drinking water with or without RG, RC and SC extracts for eight weeks. In the antioxidant enzyme activities of liver cytosol, superoxide dismutase, catalase and glutathione peroxidase activities were significantly increased in RG groups and RG with SC and RC groups compared to control group. The antioxidative activities were increased in proportion to supplementation period and amounts of extracts. These results suggest that RG, RC and SC extracts have an beneficial effect to enhance the cellular antioxidant activities in rats.

Korean ginseng(Panax gmseng C.A. Meyer) is very difficult to obtain stable production of qualified ginseng roots because of variable stresses in soil environments. In environment stresses, soil condition is the most important factor, among which nutrients, especially inorganic materials such as N, P, K, Ca, Mg, Fe, etc., influence greatly on the ginseng growth. However, present ginseng field soils in Korea contain so much amount of such inorganic materials that a variety of remarkable disorders were noted in many ginseng plantations, resulting in decrease of qualitative ginseng production. Therefore, it is required to search for genetic resources and genes tolerant to salt stress for the development of ginseng cultivars. Selection of stress-tolerant ginseng lines in fields is very difficult because it is almost impossible to control properly the environmental conditions of soil. On the contrary, it can be studied with ease to search for stress-tolerant ginseng lines through in vitro culture because of easy manipulation of stress conditions. Murashige & Skoog(MS) media with 2.5 folds of
was established for the selection of ginseng lines tolerant to salt stress under the embryo culture.
