Korean Journal of Medicinal Crop Science, volume 2, issue 3, 1994, Pages 181~186
Vegetative node and rhizome of Ligusticum chuanxiong Hort. were planted in spring and autumn and harvested after one and two years to determine the appropriate harvesting time which produced a high yield. Plant height, leaf number and branch number per plant were increased in order of rhizome planted in spring and harvested after two year(RST), rhizome planted in autumn and harvested after one year(RAO), vegetative node planted in autumn and harvested after one year(VNAO), and vegetative node planted in spring and harvested after one year(VNSO). Leaf area index and dry leaf weight in VNSO were highest on August 16, but dry weights of stem and rhizome was increased until harvesting time. The appropriate harvesting time was October 17, in RST, November 9 in RAO and VNAO, and November 13 in VNSO. Yield in autumn planting was more increased than that in spring planting and also that in RST was 443kg per 10a and increased by 2.8 times compared to RAO. However the yield in the rhizome planting was more increased by 17 percent than the vegetative node planting, the latter planting was inexpensive and economic for purchasing seed materials.

This study was conducted to evaluate the effect of herbIcides on weed control, growth characteristics and yield in Angelica gigas NAKAI, after transplanting it to the field. All herbicids treated had no effect on the emergency period, bolting rate, and growth characteristics of A. gigos. Simazin wp, methabenzthiazuron wp were slightly harmful, but linuron wp pendimethalin ec, triflurain ec had no injury on the A. gigas, even with double dosage level. Under the treatment of pendimethalin ec, linulon wp, effect of weed control valuae at 55 days after transplanting was 89.6, and 88.3 respectively with 5 or 7 species of weeds appearing. Broadleaf weeds f?ere abundant than grasses, and the major weeds were C. albam, C. flexuos, D.sanguinalis, and E. arvense. Dry yield were increased somewhat more with herbicides than by hand weeding, even with double dosage level.

Bupleurum falcatum was cultivated in plots of different soil textures, which were sandy loam(SL), loam(L), and clay loam(CL). The growth charafters of shoot and root parts in SL and L plots were better than CL one, and root yield was the most excellent in SL one. But the contents of total saikosaponins and methanol extract in its roots were the highest in CL plot. In any soil textures, one and two year old plants showed almost the same results in growth characters and saikosaponins contents. The growth and root yield of two year old plants were higher than those of one year old ones, but the contents of methanol extract and saikosaponins were lower. Flant characters were highly negative-correlated with the contents of saikosaponins and methanol extract.

This study was carried out to investigate the auxin(IAA, IBA, NAA) treatment and the effect of shading rate in Asarum sieboldii. The results obtained were summerized as follows: By the soaking treatment of auxins to the cutted rhizome enhanced root growth and plant weight. By the increment of shading rate, plant growth was much better compare to the control. Leaf fallen times appeared about 20 days more earlier at plain area then the alpain area. Root yield was much higher by the treatment of shading then the conventional cultivation so it seem to be the useful for large scale cultivations of A. sieboldii.

Artemisw spp. have been known as natural health foods from ancient time and recently, Artemisia spp. have been developed as a preference food. In the paper Artemisia spp. collected from 28 local areas in 1993 were growth in condition shaded selected some suitable species for summer cultivation. Growth characteristics and chemical components of shade-cultivated were summerized by follows. 1. The volume per
was 3.925g collected in Suncheon. Jeonnam which was most abundant, and 713g in Okcheon. Chungbuk was little. and there was difference at 5.6times. The volumes per
collected in species were plentiful of 3,420g in Hwanghaessak, 3,173g in Meongcheonssuk and 3.l48g Siljebissuk. But there were little of 2,093g in Panssuk and 2,078g in Keunjebissuk. 2. Hwanghaessk, Siljebissuk and Meongcheonssuk were good seasoning, and leaf color was light green. and also comodities was show a good result. 3. Hwanghaessuk, which was excellent quality and quantity, was include many iron and magnesium, but content of copper was low. Meongcheonssuk and pangssuk were excellent in comodities. and content of protein was abundant, but contents of catcalcium, iron, and zink were low. 4. Hwanghaessuk and Siljebissuk were a great many quantity and taste, leaf color, quality and comodity were excellent. Therefore Hwanghaessuk and Siljebissuk were most suitable cultivated in shading the light.

This experiment was conducted to obtain basic information for the establishment of in vitro initial culture system in Fritillaria thuubergii Miq. Methods of surface sterilization of scale segments as explant and effect of antibiotics added into the culture medium on contamination of explant and chilling treatment of mother bulb on bulblet formation were investigated. Portent of contamination of cultured scale segments was significantly higher in the outer scale segments which were unsuitable as initial culture explant than inner scale segments. Contamination of explants taken from inner scale of bulb was reduced by surface sterilizing explants in the solution of
sodium hypoclorite for
mimutes. Addition of antibiotics such as kanamycin, vancomycia cefotaxim, agrirnycin and agreptomycin and dithane as fungicide and
into MS medium was effective to reduce bateriological contamination, but did not work to control fungi. It had effective to delay the degree of contamination caused by fungi and bacteria haboring in cultured explants. Bulblet formation from cultured scale segments was promoted by dry storage for
weeks or moisture storage of mother bulbs for
before excision of explants. Addition of kinetin into medium could not exerted for the bulblet formation from the scale segment of dry storaged bulb compared to control. But explant taken from 6 week moisture storaged bulb formed more than 10 bulblets per explant on the medium containing

Immature ovule of intergeneric
hybrid between Platycodon grandiflorum x Codonopsis lanceolata for producing embryogenic callus. somatic embryos and plant regeneration were cultured in vitro on various medium as well as MT(Murashige Tucker)medium treated with different concentration of plant growth regulators. Embryogenic callus induction was highest in the treatment of NAA 0.5
and zeatin 0.01
added on MT medium, whereas it was lower in treatments with auxins alone. MT medium were more effective in production of somatic embryos from incubated embryogenic callus. Most favorable plant growgh regulator for producing somatic embryos was 2. 4-D 0.5
and zeation. BAP 0.01
, but hormone-free and auxins alone were less effective. NAA 0.01
added with zeation 0.5
was effective as high as NAA 0.01
alone in normal plant regeneration from somatic embryo.

The essential oils of Thymus quinquecostatus Celakov. and T. magnus Nakai, respectively, were isolated by using a modified Likens-Nickerson type steam distillation and extraction apparatus and analyzed by gas chromatography and gas chromatography-mass spectrometry. The oil content of T. quinquecostatus was 1.94%, and that of T. magnus was 1.91% in mixed leaves and stems and 0.68% in flowers. Among 38 components identified in either mixed leaves and stems or flowers the major components in essential oil isolated from T. quinquecostatus were thymol(39.8%),
and camphor(5.9%) while those from mixed leaves and stems of T. magnus were thymoI(54.7%),
and carvacroI(3.2%). The contents of
, camphene, camphor, bornyl acetate and
were higher in T. quinquecostatus than in T. maglnus but
and thymol were higher in T. magnus than in T. quinquecostatus. Comparing leaves and stems with flowers in T. magnus, peak area percentage(%) of
were higher in mixed leaves and stems than in flowers, whereas
was predominantly higher in flowers than in leaves and stems.

Effects of media and plant growth regulators on the germination of somatic embryos of Angelica tree(Aralia elata Seem.) was studied for the mass production of Angelica tree through tissue culture. MS medium was found to be the most effective for the germination of somatic embryos(65% germination rate), Among the MS medium, the medium containing 25% less inorganic salts and 1% less sucrose was found to be the most effective. Gelling agent with 0.2-0.3% gelrite promoted the germination of somatic embryo
and caused good growth of shoots and roots. 0.1 mg/l of BA and kinetin treatment caused
germination rate of somatic embryos and good growth of shoots and roots, and resulted in high percentage of dry matter. 1mg/l or 5 mg/l treatment of putrescine, and 10 mg/l treatment of spermidine caused 90% germination rate of somatic embryos and good growth of plant organs, and inhibited vitrification of regenerated plants.
