용담을 절화, 분화 및 화단용으로 개발하기 위해 기초자료를 얻고자 밀양 근교에 자생하고 있는 용담의 분포, 자생지의 환경 및 자생지별 형태적 특성등을 조사하여 다음과 같은 결과를 얻었다. 밀양근교 지역에서 자생용담은 100-300m에서부터, 800m의 고산지에 이르기까지 고도에 관계없이 분포하였고, 토양 조건은 산성 토양이며 무기물 및 유기물의 함량이 높았다. 군락지의 입지 조건은 광투과와 배수가 잘 되는 남서 방향에 많이 분포되어 있었다. 자생지별 생육 특성은 토양조건, 고도, 주변의 식생 등에 영향을 받아 초장과 잎의 형태 등에 약간의 차이가 있었다. 꽃은 길이가 4-6cm 정도였고, 5개의 수술과 한 개의 암술이 있으며 암술의 주두는 종자 성숙시기가 되면 두 갈래로 갈라지는 특성이 있었다. 잎의 형태는 대부분이 비교적 폭이 좁은 피침형 이었으며, 난상피침형도 관찰되었다. 지방은 2 심피에 1개의 자실이 있었고, 심피에 여러개의 종자가 착생되어 있었다. 꼬투리는 삭과이며, 종자는 넓은 피침형으로 양 끝에 날개가 있었다. This study was carried out to get a general information on Yongdam, Gentiana scabra Bunge var. buergei Max. which can be used as cut-flower, ornamental and medicinal plant among the native plants. To fulfil the purpose, distribution and morphological characteristics of the native Yongdam and the environments of natural habitat were estimated during the studying period. The results were summarized as follows. Native Yongdam was widely distributed around Miryang regardless of altitude. and the range of altitude for the habitat was between 100 and 800m, Soil acidity of the natural habitat were lower. and the concentration of inorganic and organic material of the natural habitat were higher than average, respectively. Main habitat of the plants were mainly located in the south-western direction which was usually drained well and had enough sun light during the day time. According to the morphological characteristics innatural habitat, there were slight differences on leaf length and shapes influenced by soil conditions, altitude and vegetation at the surrounding area. Average length of flowers was approximately 4-6cm, and each flower had 5 stamen and a pistil. Stigma of each pistil was divided into two section during the seed maturing period. Shape of leaves was usually lanceolate type with narrowed width, sometimes ovatolanceolate type was also founded. Ovary comprised two carpels and a locule, and each carpel had several seeds in it. Pods were capsule. and seed shape was lanceolate type with wings at the tips.

용담은 숙근초로서 종자번식과 분주에 의해서 번식되는데, 종자번식은 발아에서부터 개화까지 2년 이상이 소요되고 분주는 그 수가 제한되어 번식효율이 낮다. 삽목에 의한 급속번식의 가능성을 검토한 결과 발근율은 저조한 편이었으나, 줄기의 선단부가 30%발근율을 보여 대량증식의 가능성이 있었다. 삽목부위에 따라 신초길이와 신초생체중에는 큰 차이가 있었는데, 선단부를 이용한 삽목은 신초길이와 신초생체중이 10.2cm 및 500mg으로 나타나 중간부위나, 기부보다 신초 생장속도가 빨랐다. 전반적으로 줄기 선단부는 중간부위나 기부보다 발근율, 뿌리의 수와 생체중이 높게 나타났다. 이러한 결과는 식물체내에 존재하는 옥신의 농도에 기인한 것으로 판단된다. Gentiana scabra Bunge var buergri Max. as a perennial is generally multiplied by seeds and division. Seed propagation takes more than two years from germination to flowering, and division shows low efficiency of he propagation due the limited numbers. According to the results of examination on the possibilities of rapid multiplication by cutting, rooting rate was inactive. However, there was a possibilities on the mass production hoping as 30% of rooting rate when the apical of stems were used. There were significant differences between shoot length and fresh weight according to the cutting position. Cutting using the apical of stem showed that shoot length and fresh weight were respectively 10.2cm and 500mg, and the growth rate were more rapid than the middle or basal part of stems. Generally using apical of stems showed more higher values on the rooting rate, the number of roots and the fresh weight than using middle or basal part of stems. The aforementioned results may be due to the concentration of auxin in plants.

As our human society undergoes development, specialization, and advancement in civilization, a stressful environment threatens our life. Thus, We, human beings, are trying to release it through possible ways we can do. The effort to fine the way to solve the stress even becomes an additional one to us. When we define horticultural therapy to raise our social, educational, mental, and/or physical adaptability through the horticultural activities using plants this actually means that horticultural therapy is rehabilitation an recovery of the mentally handicapped persons in a narrow sense and improvement of the quality of our life in a broad sense. Horticultural therapy in the future is expected to play roles to raise the quality of our life by allowing us to release the stress, which is a pain to the moderns, and to create a comportable environment as well as to cure physically, mentally disabled persons. The Korean Horticultural therapy Research Society has been inaugurated recently. Through the development of the programs for the purpose of horticultural therapy, the society is expected to improve our mental health greatly, fulfill a positive thinking, and increase the physical adaptability by understanding interactions between human beings and plants. Furthemore, the society will play a role to produce many men of horticultural expected to make a full effort for the development of various program, which can make the general run of people feel easy to understand the horticultural therapy. Finally, We expect the society make an effort to make the field of horticultural therapy close enough to fill this as a traditional useful treatment.
