This study was carried out to examine the characteristics of root system for seedlings of Hibiscus syriacus L. on the different soil conditions as a basic study for the stock of top-root cultivars. The obtained results are summarized as follows; It was significantly different on soil hardness between upland soil with 13 kg f/cm2 until 60 cm depth and waste landfill soil with 5 kg f/cm2 until 5 cm depth. But it was not measured soil hardness under 30 cm of waste landfill soil because of waste base. But soil pH was not different between soil conditions. The root depth of 'SKK 91-3' growing on upland soil was 81.0 cm and it was significantly different as compared with that of 'SKK 91-3' on the waste landfill. In addition, 'SKK 91-3' growing on upland soil had more root weight, root width, root number, main root diameter, and shoot growth than that on the waste landfill. Therefore it was suggested that soil condition affect root growth of seedlings in Hibiscus syriacus L. and then induce top-root system.

Death of a Salesman의 페미니즘 연구

심미경 檀國大學校英美文化硏究所 1996 英美文化 Vol.5 No.-

Feminist theatre originated from the women's movement. which started from a social movement in the 1960s and expanded into a cultural aspect. Feminism suggests that women have their own unique experience of life, system of values, and world-view, which cannot be properly expressed within the traditional form of male literature or art-form. Millers's Linda of Death of a Salesman is passive and receptive rather than active and aggressive. Simone de Beauvoir states that one is not born a women, but on becomes one. It means that women are conditioned not only by the education but also by the traditional image of women. Under patriarchial system, women have been constructed as men's other. Upon this theory Linda's passivity is the result of patriarchy. Through Lacan's diagrams, we can find the arbitrariness of sexual roles. The binary opposition of man (subject) / woman (object) is not absolute but changeable. We can find that men's control over women is determined by material base and patriarchy. Through Feminist Approach to Linda, We can find Linda passivity is endowed by patriarchial system.

This sutdy was carried out to examine the present distribution and status of Hibiscus cultivars by analyzing the US and Canadian market. The obtained results are summerized as follow : 1. At present, a total of 28 cultivars of Hibiscus are on the market. Among these, twenty four are diploids and four are triploids. The hottest cultivars in the market is a triploid `Diana' sold by 21 different companies. It is followed by 'Ardens' and 'Jeanne d'Arc', following `Red Heart', `Blue Bird', 'Woodbridg e', and 'Helene'. 2. As a conservation or display purpose, several cultivars are ketp in three different arboretums in the US. These include 5 cultivars, `Blue Bird', `Celestial Blue', `Collie Mullens', 'Lucy', and `Ruber Plena', in Arnold Arboretum, and one each, 'Variegatus', at the USDA national arboretum and, `Banner' at Morton arboretum in Chicago. 3. The avarage price for triploid cultivars is $6.00 for each seedling. The recently developed cultivars like 'Helene' and 'Minerva' cost $16.00 per seedling possibly due to their plant patent right. Other cultivars produced by cuttings cost $2.00 to $ 3.00 per seedling. 4. In Canada, there are nine cultivars on the market; being diploids and one triploid, `Diana'. 5. As for the distribution of different cultivars by climatic zone, twelve cultivars are being grown in temperate area like Ohio and Iowa. However, many other cultivars are being cultivated in wamer Southern state like Galifornia. Five cultivars are reported to grow in the relatively cool area like Wisconsin and Minnesota. Even in cold area like Canada, 5 cultivars such as `Anemonaeflorus'(2n), `Ardens'(2n), 'Jeanne d'Arc'(2n), and `Luky'(2n), and 'Paeoniflorus'(2n) at Ontario and there is colder than Hamkyung Do in north Korea.

沈慶久,柳美先,李貞植 成均館大學校 科學技術硏究所 1986 論文集 Vol.37 No.1

This study was carried out to accelarate the growth of rhizome and shoot formation of Cymbidium kanran. Rhizome used as materials were prepared by seed strile culture and rhizome-tips were placed on the basal medium (Murashige & Skoog) which were supplemented with growth substances. The results obtained were summarized as follows: 1. Shoot formation at the rhizome-tips was the best in the media supplemented with 0-0.1mg/l BA. Rhizome growth was stimulated in the media supplemented with 0.1mg/l NAA and 4-8mg/l BA. 2. When organic matters were added to basal medium, a noticeable promotion of rhizome growth was observed in the medium containing activated charcoal. 3. The growth of rhizom was promoted when 4% sucrose, 3g/l pepton, or 4g/l yeast extract were added to basal medium. 4. Incorporation of 1.0mg/l BA and 10^-3M L-arginine, L-aspartic acid stimulated shoot formation remarkably under light condition. 5. Growth of rhizome according to light or dark treatment was better under dark than under 16hr illuminated light condition and the rhizome cultured under dark condition was more effective for shoot formation.

The honeysuckles constitute a sturdy group of semievergreen vines, some which can be grown in everywhere of the native mountains. As a group, they are not susceptible to serve disease troubles, which are easily grown and will usually produce a wealth of foliage, flower and fruit with very little care. They are perenial and deciduous climbing plants with strong vines, and flowered from June to September that are considerd as a good ornamental plants for Landscaping. Plants of honeysuckle are ordinarily able to be rooted from softwood or hardwood cuttings, the cutting itself being about 4-5cm long. This study was carried out to determine the effectiveness. of various rate of IBA and NAA treatment on rooting of honeysuckles (Lonicera japonica, Lonicera japonica var. aureoreticulata, Lonicera sempervirens) in the mist room and closed moist chamber. And the results obtained were as follows. Treatment of IBA and NAA increase! in the rooting percentage, rootlet number and length of root on the rooting of honeysuckle cuttings. The rooting percentage of honeysuckle cuttings with IBA 2000pprn 10 sec dip are higher than other rooting hormone treatment. IBA showed more promoting .effect than NAA treatment on the rooting of leafy softwood cuttings. Rooting percentage and number of root tended to have the hightest root system in the closed moist chamber than the mist room.
