In making gardens, garden designers establish a principle using specific colors, collect materials, and combine them with their own aesthetic senses. This study is design mothed through the species and characteristics of flowering plants used in the Barrington court created by Gertrude Jekyll and Sissinghurst's white garden created by Vita Sackville-West, both of which are the most renowned gardens that used the white color. The analysis of each individual plant used in the gardens will be based on the season, colors, shapes, plant heights and aromaticity. Through their gardens, how the flowering plants aesthetically united with each other in creating the white gardens will be reviewed. To represent the freshness of spring, Jekyll planted Campanula spp. and Lilium spp. in the garden. Vita Sackvill-West aims at the moonlight in a summer night and features Delphinium spp., Rosa mulliganii, and R. longicuspis. The color of the flowers is in white, varying from pure white, ivory and silver. To prevent monotony due to monocolor flowers, the forms of the flowers are intense. To make white flowers look better, the colors of leaves include light green, light gray and bright and greenish yellow. Overall, cool colors are used to give a mystique, coolness, cleanness and to produce an fascinating and plaintive atmosphere, getting joined with white flowers and reflected light in the night. The White Garden has made significance in the history of landscape architecture: it was the starting point of garden design through theme colors, based on the idea and technology of planting design methods that discover the potential of colors and withdraw limits. And it also made a significant contribution to the advancement of garden art with combinations by aesthetic principles.

The floristic target species (FTS) has been widely used as a important tool for environmental assessment in Korea. Here the floristic district is a key criterion for the selection and evaluation of FTS. The aim of this study is to clarify the intellectual meaning of the floristic district i.e. a sort of phytogeographical subunit. We reviewed 7 main literatures related to the floristic district. Nakai's 1919 Ulleungdo flora survey report was first to mention a region and/or province in terms of general geographical divisions. In 1977, the floristic district map of the Korea vascular plants was first described by Oh. In 1978, Lee & Yim proposed a new floristic district map dividing the central and southern regions, and the district boundaries have been adjusted by many other researchers. In the end, the floristic district map modified slightly from Lee & Yim's map was nationally recognized in 2018. However, the boundaries of floristic districts were inconsistent, both in their setting and adjustment, as well as the indicator species of the district. No basis for this inconsistency could be confirmed. We concluded that all district maps depend on arbitrary lines drawn a priori, and finally proposed the following two ecological strategies to ensure the effectiveness and practicality of the FTS as a scientific means for environmental impact assessment and national flora evaluation: (i) designing to achieve the flora list and the floristic district based on nativeness of plant distribution, (ii) constructing a habitat-based floral monitoring system.

Low impact development (LID) facilities are established for the purpose of restoring the natural hydrologic cycle as well as the removal of pollutants from stormwater runoff. Improved efficiency of LID facilities can be obtained through the optimized interaction of their major components (i.e., plant, soil, filter media, microorganisms, etc.). Therefore, this study was performed to evaluate the performances of LID facilities in terms of runoff and pollutant reduction and also to provide an optimal maintenance method. The monitoring was conducted on four LID technologies (e.g., bioretention, small wetlands, rain garden and tree box filter). The optimal SA/CA (facility surface area / catchment area) ratio for runoff reduction greater than 40% is determined to be 1 - 5%. Since runoff reduction affects the pollutant removal efficiency in LID facilities, SA/CA ratio is derived as an important factor in designing LID facilities. The LID facilities that are found to be effective in reducing stormwater runoff are in the following order: rain garden > tree box filter > bioretention> small wetland. Meanwhile, in terms of removal of particulate matter (TSS), the effectiveness of the facilities are in the following order: rain garden > tree box filter > small wetland > bioretention; rain gardens > tree box filter > bioretention > small wetland were determined for the removal of organic matter (COD, TOC), nutrients (TN, TP) and heavy metals (Cu, Pb, Cd, Zn). These results can be used as an important material for the design of LID facilities in runoff volume and pollutant reduction.

This study is about the development and creation of the public installation to enhance the contact chances with plants for the city dwellers who are living in the environment of limited green space. The researcher tried to create a floral art work at an island type bus stop on the central bus only lane, where the passers-by can enjoy the contact with plants for a second on that crowded space. The researcher made the study of various related cased world-widely and existing island type bus stop on the central bus only lane. The researcher also made pre-creation study of applicable forms and elements, and developed the prototype of the installation on the base of that study. Therefore the researcher created 1 installable screen type floral art work offering abundant contact experience to the viewers which has multiple shelves in the vertical frame to fit and be substituted by the designated wall unit of the island type bus stop structure. Also the researcher developed the prototypes of 2 small interior pieces. The meaning of this study can be found in the contribution of increasing visual experiencing rate of green space and chances of experiencing plants to create positive psychological, emotional effects by developing floral art works to be installed at crowded urban public space.

In this study, we investigated the growth and physiological responses of Iris laevigata Fisch. to shading treatments in order to suggest optimal light conditions for ex-situ conservation of the northern lineage plants. For this purpose, a control plant receiving full sunlight and different shading treatments (50%, 75%, 95%) were installed, and leaf mass per area, chlorophyll content and fluorescence response, and photosynthetic characteristics were investigated. I. laevigata developed leaves with higher photosynthetic efficiency to adapt to lower light intensity as shading levels increased. Chlorophyll content increased with increasing shading levels, and leaf mass per area decreased with increasing leaf area. The chlorophyll fluorescence responses Fv/Fm and NPQ did not change with shading, and the activity of the carbon fixation system did not differ between treatments. I. laevigata exhibited a light-saturation point equivalent to that of sun plants and maintained photosynthetic capacity similar to that of controls up to 75% shading. The apparent quantum yield of I. laevigata decreased significantly at 95% shading, indicating adaptation to lower light conditions. It seems that the photosynthetic capacity of I. laevigata decreases when grown under 95% shading level compared to full sunlight, and it is judged that the longer the light is restricted by continuous shading, the more unfavorable the growth will be.

이름의 유래는 다양하다. 아래로 향한 꽃잎 모양이 처녀 미니스커트를 닮아 붙였다고 하며, 아래의 가지런한 잎들이 치마모양을 하고 있어 그런 이름을 붙였다는 사람도 있다. 일본 이름을 잘못 번역한 것이라 보고도 있다. 처녀치마는 초본류 중 얼마 안 되는 상록성 식물로써 백합과에 속하며, 고산의 능선 북사면이나 보통 산의 웬만큼 습기가 있는 골짜기에서 흔히 자생한다. 자생지에서 보면 한 겨울 꽁꽁 언 얼음골 옆에서도 녹색을 유지하며 꿋꿋이 견뎌낸다. 연중 상록인 잎 모양도 예쁘지만 봄에 피는 꽃은 매우 아름답다.

This paper contains the results obtained by ecological investigation of flora in Sogumoon Island of the southern coast in Korea. Fifty varieties, 455 species, 322 genera and 104 family of Tracheophyta were recorded island showed a plant community predcominated by Pinus thunbergii grwon in miggle with Castanopsis cuspidata var. sieboldii, Machilus thunbergii, Litsea japonica, Albizzia julibrissin, Carpinus coreana, Carpinus laxiflora, Mallotus japonica and Clerodendron trichotomum. Sixtythree species in Sogumoon Island and 64 species in Pogil Island of evergreen broad-leaved trees were recorded by this investitgations. The plant resources of this island were 203 species. The evergreen broad-leaved trees of this island wre valuable for landscaping material plants and the evergreenherbs were valuable for foliage-plants resources. The flora breaking in this island was due to cuttinf for fuel and grazing cattle and goats. Therefore Machilus thunbergii, Ardisia japonica, Ficus miponica, Kadsura japonica, Daphniphyllum macropodum, etc. should be preserved. Autochonous flora of Buxus microphyllac, Fius erecta, Machilus thunbergii, Kadsura japonica, Ardisia japonica, Mitchella undulata, etc. should be preserved.

$\beta$-Glucuronidase (GUS) gene of Escherichia coli was introduced into sweet potato (Ipomoea batatas (L.) Lam.) cells by particle bombardment and expressed in the regenerated plants. Microprojectiles coated with DNA of a binary vector pBI121 carrying CaMV35S promoter-GUS gene fusion and a neomycin phosphotransferase gene as selection marker were bombarded on embryogenic calli which originated from shoot apical meristem-derived callus and transferred to Murashige and Skoog (MS) medium supplemented with 1 mg/L 2,4-dichlorophenoxyacetic acid and 100 mg/L kanamycin. Bombarded calli were subcultured at 4 week intervals for six months. Kanamycin-resistant calli transferred to MS medium supplemented with 0.03 mg/L 2iP, 0.03 mg/L ABA, and 50 mg/L kanamycin gave rise to somatic embryos. Upon transfer to MS basal medium without kanamycin, they developed into plantlets. PCR and northern analyses of six regenerants transplanted to potting soil confirmed that the GUS gene was inserted into the genome of the six regenerated plants. A histochemical assay revealed that the GUS gene was preferentially expressed in the vascular bundle and the epidermal layer of leaf, petiole, and tuberous root.
