Eight fungicides including prochloraz, tebuconazole, benomyl, mancozeb, thiophanate-methyl, azoxystrobin, and fluazinam were examined for their control effects on Fusarium bulb and root rot of oriental orchid, Cymbidium goeringii. Among the chemicals, prochloraz and tebuconazole were the most effective on suppression of the causal pathogen, F. oxysporum in vitro and on control of the disease in vivo. Prochloraz and tebuconazole inhibited mycelial growth of the fungi 95~100% at 10ppm a.i. and microconidial germination 75~100% at 100ppm a.i. Prochloraz and tebuconazole showed 80~92% and 84~88% protective control value on the disease, respectively. However, curative effects on infected orchid were relatively low. Other chemicals showed no or lower than 20% curative and 50% protective control value. Results indicated that prochloraz and tebuconazole can be used for the control of the Fusarium bulb and root rot of oriental orchids. However, the chemicals need to be applied prior to the disease development to achieve successful control efficacy.

We analyzed the functional fragrant components of three species of Cymbidium oriental orchids using gas chromatography-mass spectrometry (GC/MS). For the comparative analysis, C. goeringii 'Minchunran', 'Jugeumhwa', C. forrestii 'Chwigae', 'Songmae', 'Yongja', and C. faberi 'Choemae', 'Namyangmae', 'Hwaja' were investigated. Major fragrant components detected by GC/MS were selected on the basis of more than 3% value according to the analysis of peak area (%). We found that ${\alpha}$-bergamotene, which has a cytotoxic effect on breast cancer, cervical cancer, and glioblastoma, and nerolidol, which induces apoptosis of human hepatoma cells (HepG2), inhibits the growth of Streptococcus mutans and babesiosis, and has antibacterial properties, are common substances produced by C. goeringii L. Nerolidol and ${\beta}$-bisabolene, which is cytotoxic and suppresses the growth of malignant melanoma cells (B16-F10), HepG2, and leukemia cells (HL-60, K562), are major substances in C. forrestii R. Furthermore, ${\alpha}$-pinene, which inhibits the growth of gliobastoma cells (SF-767) and inhibits the anti-inflammatory action of hepatoma cells (BEL-7402); 1,8-cineole, which is a potential therapeutic agent for the treatment of gastric ulcers; and 1,3,7-octatriene, which functions as a pheromone, are the most common substances in C. faveri R. Thus, substances identified as major fragrant components in oriental orchid species have multiple beneficial applications in human health. This research forms the basis for further studies of the roles of major fragrant components in oriental orchids.

'Pattern' is of very unique nature in each and every country around the world, and its aesthetic feeling of 'pattern' has been handed down according to its nationality and cultural development process. That is, 'pattern' is ornament to symbolize each country's aesthetic standard or choice through some shape, reflecting social consciousness or religion philosophy. Mostly based upon literature survey and case study, this survey paper analytically compares oriental botanical pattern with occidental botanical figure, which has been influenced by Buddhism-Confucianism and Christian religion respectively. The results show that some patterns are commonly used in both area, while meaning differently in some cases: lotus (life), pomegranate (wealth and prosperity in orient, resurrection in occident), grape (fecundity in orient, wealth in occident), dangcho (fecundity in orient, victory in occident). And the other patterns look uniquely used either just in orient or only in occident. For instance, oriental area had its own patterns such as peony (meaning wealth and honour), peach (longevity), ume flower (happiness), orchid (fecundity); while occidental area used lily (purity), olive (peace), palm (victory), and so on. Interestingly, the botanical patterns were used as main patterns in orient whereas as minor in occident.

Forty different apartment houses were subjected to assess the status of indoor - landscaping plants found at each apartment house in Seoul for the year of 1986 and 7989. 1. Comparing with those of 1986, 46% increase in total indoor plant species and 68% increase in the number of them were observed. The most abundant sort found in 1786 was oriental orchid, African violet, Scindapsus, cacti, and Clivia, and in 1989, first with oriental orchid, cacti, Chlorophytum, Clivia and Dracaena, in that order. 2. Foliage ornamental plants were mast popularly found in both years of 1986 and 1989 when considered for horticultural classification of plants. 3. Average plant height ranged between 15 to 30 cm in the year of i986, whereas 31 to 80 cm in 1987, indicaling that the size of plants has greatly increased. 4. Kind of planters or containers was most frequently shown to be made of plastic material in both years, and the porcelain ones have significantly been increased to use recently. 5. Most indoor plants placed at the rooms were on the floor in those years, yet the use of planting shelves became particularly manifesting in the year of 1989. 6. Fittonia and cacti were the most frequently used plant materials for installing terrariums at apartment rooms In the year of 1986, whereas Adiantum and Maranta were so in 1989, indicating that the growers choose much adaptable species in apartment environments. Most of the plants grown to landscaping the indoors was apartment verandas in those years. 8. Average number of indoor plants possessed at each apartment houses surveyed for the year of 1986 was 16 different ones, whereas 27 each In 1789, shoving a noteworthy increase in the number. 9. There have been apparent increase and improvement inhabitant's indoor - plant interest in the years to pass and probably to come.

Bulbophyllum auricomum Lindl. is a rare orchid and has flowers with an attractive fragrance. The present study investigated the tissue culture method for micropropagation. Capsules derived from artificial self-pollination were obtained for the best seed germination in MS basal medium. Plant growth regulators (1.0 mg·L^-1 of BAP and 2.0 mg·L^-1 of NAA) were affected by callus induction from subcultured pseudobulb explants. For the callus subculture, different natural plant extracts were tested in 11 treatment media. Among them, MS medium with 150 mL·L^-1 of coconut water was generally effective in fresh weight (1.75 ± 0.08) and (3.01 ± 0.20) of callus proliferation and PLBs induction at 1 and 2 months, respectively, followed by an MS combination of 30 g·L^-1 of banana and 20 g·L^-1 of potato extract. The results of a comparative study of different MS mediums containing plant growth regulators with a natural extract combination and MS medium supplemented with natural extract only showed that MS medium supplemented with a combination of natural extracts (150 mL·L^-1 of coconut water) and plant growth regulators (2.0 mg·L^-1 of BAP and 1.0 mg·L^-1 of NAA) obtained the highest shoot regeneration (3.37 ± 0.17) and (6.41 ± 0.68) after 1 month and 2 months of culturing, respectively.

Kwon Kisoo is one of the most promising artist in Korea. His paintings portray a lot of metaphors and philosophies in oriental art. As an artist, he adapts both oriental and contemporary ideas to make his paintings. His main motifs are Plum blossoms, Chrysanthemum, Orchid and Bamboos. These plants are known as 'Sa-gonja' in Korean but translated as the 'Four Gracious plants' or the 'Four Gentle Plants in english'. These noble plants represent the four seasons. They grow in different weather conditions. In oriental art, these plants are considered very important for their qualities. These qualities are important attributes for gentlemen in literati painting. The drawing of the 'Four Gracious Plants' in Kwon Kisoo's paintings is simplified. He uses lines, shapes and colour to create contours of the motifs. In his paintings, there is another icon he calls 'Dongguri'. Dongguri is the main character in Kwon Kisoo's paintings. It was developed in 2002 by fast brush strokes. Dongguri is an admired character because it looks like very cute in Kwon Kisoo's paintings. Dongguri is always seen living in the midst of the 'Four Gracious Plants'. The 'Four Gracious Plants' with other landscape features like rocks and mountains are places 'Dongguri' lives. Dongguri is also often found performing a lot of actions like climbing, running, sitting etc. All these actions depict metaphors which have been unraveled in this study.
