The shoot tips of Delphinium cv. Princess Caroline were cultured on the MS medium supplemented with cytokinin and auxin alone or in combination. Among cytokinins, BA was most effective in shoot multiplication, adequqte concentrations being 1.0-5.0 mg/L. Shoot multiplication was very favorable on the media with 1.0-3.0 mg/L BA and 0.1-0.5 mg/L IAA. Additions of BA and IAA did not stimulate shoot multiplication, but increased a little fresh weight. Shoots were scarcely rooted on the media with IBA or NAA, and were not done utterly on the media containing activated charcoal. Therefore, shoots were treated by Rootone and planted in the cultural media for in vivo rooting. The highest rate of rooting was 68% in the mixed cultural medium composed of Perlite 1 and Vermiculite 1.

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 purpose of this study was to suggest the basic data for establishment of wildflower pastures. The experimental design includes two treatments: Native wildflower pasture (NWP, Kentucky bluegrass + native wildflower 8 species) and Introduced wildflower pasture (IWP, Kentucky bluegass + introduced wildflower 24 species). The field trials were carried out on the experimental pastures plots at Chungnam National University throughout from Sep. 2006 to Dec. 2007. The results obtained are as fellows: In terms of the flower color in the wildflower pastures, the IWP was found more various than the NWP. But such problems as seasonal distribution and continuity were raised and moreover the time of flowering depended mainly upon the spring season. Even though the flower color in the NWP did not show up its variousness, seasonal distribution and continuity were found comparatively satisfactory. To perennially maintain the botanical composition, the variousness of wildflower species are found important after examining locally the beginning rearing and flowering characteristics of wildflowers as well as the basic turfgrass. Moreover, when the wildflower pastures was constructed in autumn, since most of the introduced wildflower were annuals, it maintained various botanical composition before wintering, but after wintering the botanical composition were found simplified due to the winter tolerance. The NWP did not show any problems in the winter tolerance but it could not make the botanical composition diversified. Accordingly, to maintain the wildflower pasture for many years, diversifying wildflower species based upon perennials including annuals seems to be good.

Karl Foerster had the most significant influence on the establishment of the German garden culture. From the viewpoint of planting design, in particular, he greatly contributed to the selection of new materials and the distribution of gardens. Therefore it is worth re-exploring his garden in that he triggered the use of natural planting that is widely used these days and already used ornamental grasses in his garden designs. This study aimed to review Foerster's garden to understand his planting design methods and their historical significance. The results suggest: Firstly, in spatial structure he designed sunken gardens influenced by the climate and triggered the use of natural planting by applying naturally open meadow, ferns and grasses. Secondly, in terms of the use of materials, he pointed out the necessity to use perennial plants. He bred perennial plants that the general public could easily grow and that were resistant against cold and created show gardens to demonstrate the characteristics of the plants and possible combination methods to the public. Thirdly, in terms of the aesthetical principles of his planting design, he focuses on colors and seasons and was interested in blue, yellow and white colors. In doing so, he developed new varieties such as Delphinium, Rudbeckia and Phlox. He emphasized the necessity of seven seasons, which served as the ancestor of contemporary winter gardens.

This study was carried out to investigate the flora of Jingangsan Mt. (Ganghwa-gun). The vascular plants identified during the 11 round field surveys were a to total of 560 taxa: 114 families, 336 genera, 495 species, 7 subspecies, 53 varieties, 4 forms and 1 hybrid. A high plant diversity were Poaceae (11.0%), Asteraceae (10.8%), Cyperaceae (8.8%), Rosaceae (4.6%) and Lamiaceae (4.3%) in regular order. The four taxa of Korean endemic plants such as Viola seoulensis Nakai, Salix koriyanagi Kimura ex Goerz, Hemerocallis hakuunensis Nakai and Polygonatum infundiflorum Y. S. Kim, B. U. Oh & C. G. Jang were collected. The vascular plants on the red list according to IUCN evaluation basis were found to be four taxa: Near Threatened (NT) species of Delphinium maackianum Regel, and Not Evaluate (NE) species of Mosla japonica (Benth. ex Oliv.) Maxim., Carex paxii Kük. and Polygonatum infundiflorum Y. S. Kim, B. U. Oh & C. G. Jang. The floristic regional indicator plants found in this area were 28 taxa comprising two taxa of degree IV, three taxa of degree III, eight taxa of degree II, and 15 taxa of degree I. In addition, the naturalized plants were identified as 44 taxa and the percentage of naturalized index (NI) was 7.9%, and Urbanization Index (UI) was 13.7%.
