  • 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.

  • 소치 허련(小癡 許鍊,1808~893)은 조선 말기 대표적 남종 문인서화가이며 남도 문인화의 시조로, 초의선사와 추사 김정희의 문하에서 문인의 학문적 면모와 화원의 능숙한 화법을 모두 체득해 '사의화(寫意畵)'를 이룬 직업형 문인화가였다. 허련의 산수화는 그의 화격을 높이 산 김정희의 지도에 의해 형성되었으나, 추사 사후 그의 나이 70세경에 본격적으로 그리기 시작한 묵란화는 '추사란(秋史蘭)'의 양식과는 관련이 없고, 전체적으로는 고법(古法)을 따르면서도 거칠고 호방한 필치의 사의성을 띠고 있어 주목된다. 허련의 묵란화는 사군자류 중 화란법(畵蘭法)을 남길 만큼 관심을 가졌던 분야임에도 전체적인 작품의 조사나 분석이 이루어지지 않고 있다. 이에 본고에서는 화란법과 제발(題跋), 인문(印文)에 나타난 난화관(蘭畵觀)을 통해 그의 묵란화 인식을 살피고, 화보를 임방하고 당대 화풍을 수용하면서도 개성적인 필묵의 운용으로 형성된 소치란(小癡蘭)의 면모를 파악해보고자 한다. 특히 허련은 당시 묵란화의 대가인 이하응이나 조희룡과 화우(畵友)로 지내지만 난 그림에 있어서는 김정희의 난화론을 바탕으로 삼아 초기 지두란(指頭蘭)을 그리는 등 자신만의 화란법을 형성하고 예술세계를 구축한다. 또한 난화는 유가적 전고(典故)를 바탕으로 그리지만 제발과 인장의 내용을 통해서는 유가적 성격뿐만 아니라 도가 불가적 의미까지 더해져 허련의 인생 지향과 사유세계를 유추할 수 있다. 이러한 복합적이고 다양한 철학과 심미의식이 반영된 허련의 묵란화는 시기에 따라 변화 과정을 거치며 만년에 사의 묵란화를 형성한다. 즉 그는 직업형 화가였음에도 말년에 더욱 활발히 제작했던 사의란을 통해 조선 사대부의 이상에 더욱 가까이 다가가려 했음을 알 수 있고, 소치란은 문인의 표상을 실현하려는 사의적 시각과 의지의 발로였다는 것을 보여준다.

  • 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.

  • 표암 강세황(1713~1791)은 그림이나 글씨 시 제발 인장뿐만 아니라 탁월한 서화감식과 비평으로 조선 후기 회화의 큰 흐름을 주도했던 대표적인 문인서화가이다. 그는 79세의 장수를 누리며 다양한 화목(畵目)의 작품을 제작했는데 특히 말년에 천착했던 문인화류의 사군자화는 조선 말기 묵란화 유행의 바탕을 마련했다는 점에서 주목할 필요가 있다. 또한 그는 조선시대 화가 중 처음으로 사군자화를 갖추어 그렸는데, 작품량이 많고 회화사적 연구 가치가 있는 '묵란화(墨蘭畵)'에 대해서는 적극적인 연구가 진행되고 있지 않다. 따라서 이 논문은 강세황의 묵란화에 대한 기록과 작품 연구를 통해 그의 묵란화 인식과 지향을 살피고자 시도되었다. 먼저 강세황의 묵란화 기록에는 사생(寫生)과 고화(古畵)의 연습, 화보(畵譜)의 임방을 고루 중시했던 그의 작화태도가 나타나 주목된다. 18세기 예림의 종장 강세황은 고인(古人)의 뜻과 정신이 집약된 고화의 임방(臨倣)을 중시했으며 그림을 '우의(寓意)'와 '재도(載道)' 등의 수단으로 인식했다. 즉 그의 지속적인 화보임방의 작화방식에서 수기적(修己的) 가치관과 회화관을 읽을 수 있다. 다음으로 그의 이런 회화관이 녹아 있는 묵란화는 양식적 분석을 통해 30~40대의 전반기와 절필기를 끝내고 군자화에 몰두했던 60대~79세인 후반기로 나누어 볼 수 있다. 그는 전반기에 "개자원화전"을 주로 학습하였고, 후반기에는 "십죽재서화보"나 "매죽난국사보" 등의 화보를 학화(學畵)하였다. 때문에 전체적으로 그의 묵란화는 전시기(全時期) 화보 의탁이 농후하다고 할 수 있다. 그럼에도 묵란화를 다작했던 70대는 화보의 의고와 임방을 주지하면서도, 그것을 능숙하게 소화해 고아하고 단아한 '표암난'을 완성하여 조선 후기 묵란화 발전에 일조하였다. 마지막으로 강세황의 묵란화풍과 관련 있는 당시(當時) 화가들에 대해 살펴보았다. 서화합벽첩을 만들며 서화로 교유했던 심사정이나 최북의 묵란화풍에서 강세황의 영향이 감지되어 앞서 언급한 문인들의 상찬과 아울러 18세기 조선 화단에서의 강세황 묵란화에 대한 위상을 짐작할 수 있다.

  • 현재 원예계에서 난의 재배는 중요한 품목이며, 화훼계에서 차지하는 비율이 높다. 우리 나라의 5개 자생지에서 채집한 춘란과 난 농원에서 조직 배양하여 재배한 심비디움류의 뿌리에서 공생하는 균을 분리하고, 또한 염색하여 현미경 관찰을 하였다. 난의 뿌리세포에 침투한 균은 읽히고 꼬인 정도가 다양한 균구를 형성하였다. 균구를 이루는 균사들의 직경은 가느다란 것에서 굵은 것까지 다양했고, 소화 단계상 다양한 균구를 관찰할 수 있었다. 난 뿌리속에 있는 내생균근균을 순수 분리하여 동정하였으며, R. repens와 R. endophytica var. endophytica로 동정하였다. 이들의 균을 제주한란과 오트모론을 이용하여 공생관계를 측정하였다. 또한, 여러 가지 동양란과 서양란의 접종하여 개체당 생체량의 증가율을 측정하였을 때 난균근균에 감염된 실험구의 난이 모두 대조구의 난보다 높은 증가율을 나타내었다. 이것으로부터 우리나라의 자생란인 보춘화에서 분리된 R. repens가 난과식물에 대해 공생 능력이 있는 난균근균임을 확인하였다.

  • 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.
