임상의 동일 공간에 생육하고 있는 제비꽃속 세 종(고깔제비꽃, 왜제비꽃, 남산제비꽃)의 영양생장적 특징과 광량의 관계를 통해 각 종의 전략자적 특징을 알아보았다. 본 연구는 광주광역시에 위치한 무등산의 다섯개 지점으로부터 1994년, 1995년, 2000년에 중점 조사가 수행되었고, 2007년과 2010년 추가 조사가 진행되었다. 각 종의 집단 내 개체수의 변동, 개체의 건중량과 엽수, 조도에 따른 종의 분포 유형 분석을 통해 세 종이 임상의 광양에 의해 서로 다른 생태적 지위를 얻고 있음을 알 수 있었다. 고깔제비꽃은 K-전략자로서, 왜제비꽃은r-전략자로서, 남산제비꽃은 두 종의 중간에서 그 생태적 지위를 차지하는 것으로 해석되었다. In this study we investigated the relationship between characteristics of vegetative growth of three species of Viola (V. rossii, V. japonica, and V. dissecta var. chaerophylloides) and light in order to explain how these three species could live together under a closed space in a forest. This studywas carried out at five sites in Mudeung-san (Mt.) on 1994, 1995, and 2000 and additional investigations were performed on 2007 and 2010 at the same sites. In order to find the relationship, three main investigations were conducted: counting number of individuals for each investigated year, measuring dry mass and counting developed leaves per plant, and finding presenting patterns of each species with reference to incidence of light. As a result, we found that three species could share the closed space in a forest because of their different adaptive strategies like V. rossii as Kstrategist, V. japonica as r-strategist, and V. dissecta var. chaerophylloides as an intermediator between two species.

본 연구는 식물염색의 생물 산업화에 있어서 기초가 되는 지속적 염료 공급의 가능성을 제시하기 위해 수행되었다. 생물 산업은 양질의 재료식물의 지속적 공급에 기반을 둔다. 전래의 중요한 염료식물인 지치는 과도한 채취로 절멸 위기에 처해 있으며 재배 또한 어려운 실정이다. 조직배양을 통해 증식시킨 모상근(hairy root)을 이용하여 지치의 알코올염색을 시도하였다. 1. 식물염색은 생물 산업으로 발전되어야 한다. 2. 생물 산업에는 고품질 식물재료의 지속적 공급이 필요하다. 3. 중요한 염료 및 약용자원식물인 지치는 희귀식물이 되었다. 4. 조직배양으로 지치를 대량 증식하고,알코올로 색소를 추출한다. 5. 공예와 생물학의 연결로 식물염색의 생물 산업화가 가능해진다. This study has been carried out to demonstrate the possibility of a sustainable supply of dyeing stuffs , which is the basis for industrialization of plant dyeing. The biotechnology industry is based onthe sustainable supply of quality raw plant s. Gromwell, one of the more important traditional dyes, is at risk of extinction due to heavy culling. Furthermore, its horticulture has turned out to be very difficult. This study tries to alcohol(ETOH extracting gromwell dye from hairy roots cultivated through tissue culture. 1. Plant dyeing should be developed into an industry. 2. The biotechnology industry requires a sustainable supply of quality raw plants. 3. Gromwell, an important dyes and medicinal plant, has become an endangered species . 4. Dye is extracted from gromwell using ETOH, which is cultivated on a large scale through tissue culture. 5. Linkage of cut craft with biology enables the industrialization of plant dyeing.

Rice (Oryza sativa L.) calli containing both embryogenic callus (EC) and nonembryogenic callus (NEC) regions were initiated from the mature seed on MS medium supplemented with 2.0 mg/L 2,4-D, 0.5 mg/L kinetin. The calli were developed into two callus type which can be distinguished by visual examination depending on color and appearance. In order to illucidate the polypeptide composition between EC and NEC, the total protein extracted from two types of callus was analysed by electrophoresis. By one-dimesional analysis of SDS-PAGE and Isoelectric focusing, several protein bands showed quantitative and qualitative difference in each type of callus. The further analysis of the total protein with two-dimensional electrophoresis showed at least 20 EC specific protein and 10 NE specific protein. Also 3 specific protein spots showing microheterogeneity of 90, 65, 50 kD were detected in EC, while a series of acidic heterologous protein spots were visualized in NEC.

The studies were carried out to know shade tolerance of the plants for the urban forest aromatic bath. The one to two year old potted seedlings were grown under the one of the five light conditions such as 100%, 50%, 30%, 10% and 2% of the full sun light intensities. Pinus densiflora S. et Z., P. sylvestriformis (Takenouchi) Chien., Thymus quinquecastatus Celak, Lonicera japonica Thunb, and Zingiber officinale Roscoe showed decreasing tendencies in height and root collar diameter growth, and dry mass production as the light intensity decreases. Exceptionally Thuja koraiensis Nakai showed the best growth in the 50% of full sun light intensity. Athyrium yokoscense (Fr. et Sab.) H. Christ showed better growth in the relative light intensity of 10 to 15% than in the in the relative light intensity of 25 to 30% in the bath green house.

The studies were carried out to develop an urban forest aromatic bath in the idle space within city area for handicapped persons, patients and city workers, who having less chance to visit the natural forest aromatic bath. The environmental conditions were checked in the experimental double vinyl house where native and exotic aromatic woody and herbaceous plants were growing with minimum energy input in the periods of mid-winter and mid-summer. The growth and photoperiodic responses of the plants to the low and high temperatures were observed during winter and summer respectively. The most of herbaceous plants in the double vinyl house with the controlled minimum night temperature of -2℃ had no winter injury but did not grow and started the growth in April. The exotic herbs such as Catnip faassen's(Nepeta x faassenia) and Lemon bergamot(Monarda citriodora) grew better in the longer photoperiodic conditions. The growth rates of Abies koreana, Thuja koraiensis and Pinus sylvestriformis in the early spring were affected mainly by the night minimum temperature and less affected by the photoperiodic conditions during winter. The native aromatic herbs such as Robdosia japonica, Molsa punctulata, Agastache rugosa and Codonopsis lanceolata showed stimulatory growth at the 16 hours day-length in case of the high temperature vinyl hose: The height and root collar diameter growth of pine seedlings were inhibited in maxim temperatures over 40℃ during summer.
