Orchids are evolutionally known to be the most advanced plants in the order Liliales, and comprise approximately 1,000 genera and 35,000 species world-wide. In Korea, more than 110 species of Orchidaceae have been reported to be cultivated or to be collected in the wild. Orchids aye mostly dependant on orchid mycorrhizae(OM) throughout or in part of their life cycle. The OM endomycorrhizae belonging to basidiomycetes or rarley ascomycetes are needed for orchid seed germination. Various fungi, including plant pathogenic, antagonistic and symbiotic fungi, were isolated from the roots of orchid native to Korea. The OM fungi collected from the roots of Cymbidium goeringii were three species of Rhizoctonia namely, R. repens (anamorph state of Tulsanella repens), R. endophytica (Ceratobasidium cornigerum), and an unidentified species (possibly an anamorph of T. calospora). These symbiotic fungi induced peloton in the cortical cells of orchid roots, and differed biologically and in 18s rDNA sequences from plant pathogenic Rhizoctonia species. Also, the mycorrhyzal fungi enhanced the orchid root absorption of nitrogen sources and minerals from the soil. The activity of mycorrhizal fungal hyphae in the roots caused prevention from pathogenic fungi. In nature, the peloton is observed in the cortical cells of Cymbidium goeriingii roots, indicating mycorrhizal colonization in the native orchid roots. On the other hand, pathogenic fungi such as Fusarium and/or Rhizoctonia species are mostly isolated from commercial orchid plants. These suggest that application of symbiotic mycorrhizal fungi should be needed for orchid cultivation in nurseries and at the time of transplanting.

Ten isolates of the orchid mycorrhizal fungi were isolated from the roots of Korean native orchid plants (Cymbidium goeringii) which inhabitate mainly in southern and western areas of Korea. The growth rates and color of the isolates in potato dextrose agar (PDA) were various. Microscopic observations of the hyphae isolated were identified as Rhizoctonia repens and R. endophytica var endophytica or their related species. R. repens was isolated from the roots of the Korean native orchids, but R. endophytica var endophyica was only isolated from the roots of the commercial orchids introduced from foreign countries. Also, the polymorephic patterns of genomic DNA extracted from selected isolates were compared with those of DNA extracted from the orchid mycorrhizal fungi isolated previously and similar band patterns were observed among those isolates. Five isolates of R. repens were selected and cultured at the oatmeal agar for investigating their symbiosis with orchid plants. The symbiotic specificity between orchid plants and isolated orchid mycorrhizal fungi was observe by growing orchids about six months in the greenhouse. The symbiotic responses of the commercial orchid plants with selected isolates were quite different form different isolates due to the genetic variations.

Orchid seeds are nearly microscopic in size. Because of that, many fanciful theories were proposed for the origin of orchids. Almost 400 years separate the time when orchid seeds were seen for the first time and the development of a practical asymbiotic method for their germination. The seeds were first observed and drawn during the sixteenth century. Seedlings were first described and illustrated in 1804. The association between orchid and fungi was observed as early as 1824, while the requirement for mycorrhiza for seed germination was established in 1899. An asymbiotic method for orchid seed germination was developed in 1921. After Knudson's media B and C were formulated, orchids growing and hybridization became widespread. Hybrids which early growers may not have even imagined became possible.

The orchid symbiotic fungi were isolated from the roots of Korean native orchid (Cymbidium goeringii) collected and Chinese orchid (C. sinense) obtained from greenhouses. They were identified as a species of Rhizoctonia, based on the sequences of 18r rDNA, the microscopic observations of mycelia, and the symbiotic relationships with commercial orchids. The isolate collected from Chinese orchids was revealed to be a species of Ceratobasidium endophytica, and to be different from the other isolates at the thickness of the mycelia stained in the root cells of Korean native orchids. The other isolates collected from the Korean native orchids were considered to be a species of Tulsanella repens (anamorphic: Epulorhiza repens) or its related one. The physiologic or microscopic variations were oftenly observed among them, but the tendency of grouping these in the 18s rDNA sequences were observed to be consistent with those of the localities collected. The further taxonomical segregating for Korean symbiotic fungi was not made because the information concerned were limited in this moment, but was recognized as based on the sequences of 18s DNA.

Sochi Heo Ryun (小癡 許鍊, 1808-1893) was a literary artist of Chinese paintings of the Southern School during the late Joseon dynasty and the founder of paintings in the literary artist's style of Jindo County in South Jeolla Province. He was also a professional literary artist who acquired both learning and painting techniques under Choui (a Zen priest) and Kim Jeong-hee's teachings. Heo Ryun's landscape paintings were influenced by Kim Jung -hee. However, his ink orchid paintings, which he began producing in his later years, were not related to the 'Ink Orchid Paintings of Chusa (秋史蘭)'. His ink orchid paintings as a whole drew attention as he followed the old methods but still used rough brush strokes . Ordinary orchids were drawn based on Confucian content. However, his Jebal (題跋) and seal (印章) contain not only Confucian characters but also Taoist and Buddhist meanings. Therefore, it is possible to guess his direction of life and his private world of suffering. Ryun's ink orchid paintings reflected a variety of philosophies and aesthetic sensibilities. He went through a process of stylistic change over time and formed an 'Ink Orchid Painted Thought' in later life. The main characteristic of Sochi's ink orchid paintings is that he formed his own special methods for orchid paintings by mimicking the Manuals of Paintings. He drew orchids with his fingers in the beginning. Then, Jeongseop, Lee Ha-eung, Cho Hee-ryong, and others developed an organic relationship with the painting style of ink orchid paintings. Then in later years, orchid paintings reached the point of 'Picture Painted Thought (寫意畵)'. The above consideration shows that ink orchid paintings, which he produced until the end of his life, were the beginning of his mental vision and will to realize the image of a literal artist.

The purpose of this study lies in pursuing the unique plastic arts with the orchid motif which has the graceful colors and a variety of shapes beauty. Another aspect of this study intends to crease the modern costume design with the high added value by expressing the texture according to the material and tissue development for the continual improvement and promotion of the modern costume design in the handicraft art area. The results through the theoretical survey and the work production are as follows : First, the orchid which has the various shapes and colors provides the designers with the unique plastic arts and the possibilities for the unlimited expressions as the design motives. Second, we can see the creation of cubic plastic beauty in the moving line, as the material which has the flexible and brilliant shape fixation, used for expressing the shape beauty of the orchid. Third, this study reveals the extension of expression areas as a characteristic of the plastic arcs by applying handicraft techniques such as dyeing, corded tuck, flounce, crochet, weaving, beads embroidery, and art flower to the costumes for developing the unique material and texture. Finally, the possibility is suggested that the desires of the moderns searching for their own individualities can be met by creating the costumes with the added vague as the exposure of esthetic consciousness through the handicraft expression techniques.

This paper is a study about the Gang Sehwang's (姜世晃 1713~1791) Ink Orchid Painting. Gang Sehwang is a representative literati gentleman who painted Four Gentlemen, for the first time, during the late Joseon Dynasty. There are 20 pieces of Ink Orchid Painting of his in Korea. His recognition of the Ink Orchid Painting can be understood through his records and analysis of his Ink Orchid Painting. He considered the sketch from the nature (寫生), practice of old paintings (古畵), and copy-training of the manual of paintings (畵譜). Particularly, Gang Sehwang focused on the copy-training of old paintings (古畵臨倣) which integrates the will and spirit of old literati gentlemen. This means that he had recognized the picture as a means of 'literature carrying morality (載道). Also, we could read self-discipline (修己的) values from his continuative copy-training of the manual of paintings (畵譜臨倣). Next, his Ink Orchid Painting were divided into the first half of the term (his 30s to 40s) and the second half of the term (his 60s to 78 years old). He had polished up on the Jieziyuanhuazhan ("芥子園畵傳") during the first half of the term and on the Shizhuzhaishuhuapu ("十竹齋書畵譜") or the Maejuknanguksabo ("梅竹蘭菊四譜") during the second half of the term. Therefore, it could be understood that he had depended on the manual of paintings (畵譜) for a long time. Nevertheless, he had completed the elegant and graceful Pyeoam Orchid (豹菴蘭)' based on his skill of the manual of paintings (畵譜) in his 70s. Finally, the 18th century Ink Orchid Painting and painters who lived (worked) at that time were investigated. He made?? the Albums of Calligraphy and Painting (書畵合壁帖) with Shim Sajeong (沈師正) and Choi Buk (崔北). They also interacted with each other by Calligraphy and Painting (書畵). Also, Yi Insang (李麟祥) and Im Heeji (林熙之) contributed to the diversification of the 18th century Ink Orchid Painting style by imitating Ink Orchid Painting with the manual of paintings (畵譜). Moreover, it is meaningful that the Ink Orchid Painting of Gang Se-hwang and the18th century Ink Orchid painters influenced the foundation of the 19th century Ink Orchid Painting fashion.

This study was to identify the orchid mycorrhizal fungi and to test whether the orchid plants antificially inoculated with this fungus showed better growth them uninoculated plants. Symbioses in the root cells of the native plants of Cymbidium goeringii collected were observed and the digestive forms of peletons were also observed in various native roots. Two types of hyphae, thick $(7{\sim}10\;{\mu}m)$ and thin $(2{\sim}4\;{\mu}m)$ in thickness, were conclusively found to be from various native orchid roots. The symbiotic fungus was isolated by several agars and identified as a Rhizoctonia repens or a R. endophytica var. endophytica. Symbioses on the plantlets of C. karnan and Cymbidium hybrid 'Onomoron' were evaluated as the isolates inoculated on oatmeal agars. The growth of plantlets were measured with the formations of mycorrhizae in the roots. R. repens was shown to be the better isolate than the other in growth stimulation of plantlets on oatmeal agars when grown for two months. The two types of hyphae in the root cells under nature were speculated from the different fungal isolates of Rhizoctonia. Further isolates would be needed for application works for the orchid industries.

Moth orchid plants with yellowing blight and root rot symptoms were collected, and a total of 54 isolates of Fusarium spp. was obtained from roots and leaf bases of the diseased plants. The isolates were identified based on their morphological characteristics. Out of the 54 isolates of Fusarium spp., 42 isolates were identified as F. solani, 5 isolates as F. oxysporum, and 7 as F. proliferatum. Isolates of the three Fusarium spp. were tested for pathogenicity to moth orchid plants by artificial inoculation. All the Fusarium spp. induced root rot of the host plants. The symptoms progressed up to the basal part of the leaves, which later caused yellowing blight. The symptoms induced on the plants by artificial inoculation with the Fusarium spp. isolates were similar to those observed in greenhouses. The present study reveals that F. oxysporum, F. proliferatum, and F. solani cause root rot of moth orchid, and that F. solani is the main pathogen of the disease.
