손병구 한국생명과학회 2003 생명과학회지 Vol.13 No.6

장미 삽목묘에 돌리도를 주기적으로 관주하여 초장, 경직경, 엽수, 엽면적, 최대 근장 등 생육반응을 검정한 결과 돌리도의 관주처리는 삽목묘의 초기생육에 큰 차이는 없었으나 60일 후의 후기생육은 향상되었다. 장미 유목에 돌리도를 관주 처리하면 초장, 경직경의 향상과 줄기의 부피생장 더불어 엽수 및 엽면적이 증가되었다. 돌리도를 주기적으로 관주한 장미유목은 이를 처리하지 않은 대조구에 비해 초장이 6.4∼11.0 cm, 경직경은 0.70∼l.14 cm증가하였고, 엽면적도 $136cm^2$ 높았다. 또한 돌리도의 처리에 의해 총 생체중 및 총 건물중을 증가시켰는데, 그 효과는 생육후기로 갈수록 현저하였다. This experiment was carried out to investigate the effect of subirrigation of Dolrido on the growth and development of stem cutting and young roes plant. Plant growth was measured at 20, 40, and 60 days after subirrigation of Dolrido. Plant height, stem diameter, number of leaves, leaf area and root length of cutting rose subirrigation were more affected than those of control. The growth of young seedling was significantly affected by subirrigation of Dolrido. Plant height, number of leaves, stem diameter, leaf area, fresh and dry weight were increased with subirrigation of Dolrido. However, T/R ratio was not affected by subirrigation of Dolrido. Growth of seedlings was promoted after 60 days treatment of Dolrido.

자생식물 중 절화, 분화 및 화단용으로서 가치가 높고, 한약으로서 이용 가능한 용담의 발아성과 발아과정중 형태형성에 관계하는 식물체의 특성을 이해하기 위해 각 부분의 내부조직을 광학현미경과 주사전자현미경으로 관찰한 결과는 다음과 같다. 용담은 채종직 후 발아하여 휴면이 없거나 극히 짧았다. 성숙종자는 미숙종자보다 높은 발아율을 보였고, 미숙종자는 저장기간이 경과할수록 수명이 단축되었다. 종자의 수명은 190일 정도였다. 발아과정중 수반되는 형태형성을 관찰한 결과, 치상직 후에 종자는 수분을 흡수하여 종피가 팽창하였으며, 2일 후에는 유근이 출현되었다. 치상 4일째에는 유근에서 근모가 발생되었고, 파종 6일 후에는 자엽이 전개되었다. 치상 8∼10일 후에는 완전한 식물체로 발육되었다. 잎의 및의 조직을 검경한 결과 중앙맥과 지맥을 구별할 수 있었으며, 관다발이 잘 발달되어 있고, 단층의 표피조직과 책상조직 및 해면조직등이 관찰되었다. 책상조직은 대개 1열의 세포층으로 되어 있었다. 기공은 잎의 이면에만 분포하였고, 기공의 형태는 공변세포 주위에 부세포가 존재하지 않는 불규칙형으로 배열되어 있었다. 줄기 조직은 단층의 표피조직과 유조직으로 구성되어 있는 피층, 그리고 원형의 대를 이루고 있는 유관속을 관찰 할 수 있었다. 줄기의 유관속 조직배열은 둥근 원형의 띠모양을 나타내었다. Gentiana scabra Bunge var buergeri Max, can be widely used such as cut-flower, ornamental and medicinal plant among the native plants. Microscopic and Scanning electron microscopic observation plant were carried out to estimates the characteristics correlated with germinability and germination process, and the results were as follows. The seeds were germinated just after harvest, and it means that there is no or little dormancy of the seeds. Matured seeds showed higher germinability than those of immatured. As the storage period was longer, immatured seeds showed shorter longevity than those of matured. The average longevity was about 190 days. According to the observation results of morphological changes during the germination, seed coat was expanded with water absorption immediately after seeding, and radicals were observed 2 days after seeding. Root hairs were formed behind the growing tip of the root on 4 days after seeding and cotyledon were unfolded on 6 days after seeding. In the microscopic observation of leaf tissues, it could be easily distinguished between midrib, and leaf blade, and also observed upper epidermis, palisade parenchyma and spongy parenchyma consisted as a sing1e layer. Palisade parenchyma was consisted of a single layer of cell. Stomata were restricted lower surface, arranged as anamocytic type, and surrounded by guard cells. In the microscopic anatomy of stem were consisted of cortical layer, forming a single layer of epidermis and parenchyma, and vascular bundle which was consisted of continuous cylinder of vascular tissues.

자생식물 중 실내분화용, 절화 및 화단용으로서 가치가 높고, 한약으로서 이용 가능한 용담의 기내개화 및 대량증식 체계를 확립하기 위하여 식물체의 부위 및 생장조절제의 효과를 시험한 결과는 다음과 같다. 화뢰의 출현은 0.5mg/l kinetin과 GA_${3}$를 첨가하였을 때 가장 많았으나 그 효과는 kinetine이 더 좋았다. 최적의 GA_${3}$나 kinetin농도일 때 두가지 생장조절제를 혼용하면 오히려 화뢰형성수가 감소되었고, 저농도에서는 상호작용의 효과가 있었다 화뢰가 50% 형성되는데 걸리는 주수(T_50는 0.1mg/l GA_3가 첨가되었을 때 Kinetin의 농도에 관계없이 11-14주이었다. 측지 발생은 GA_${3}$의 효과가 kinetin보다 좋았고, 농도는 모두 1.0mg/l까지 높을 수록 좋았다. 중간정도의 농도(0.5mg/l)에서 두 생장조절제간의 상호작용이 인정되었다. 뿌리의 형성은 GA$_{3}$의 농도가 높을 수록 감소하였다. 꼬투리의 크기가 8mm까지 클수록 발아력이 높았으며, 꼬투리의 크기가 작을 수록 비정상적인 식물체가 많았다. 배지에 GA_${3}$/l 첨가는 발아력을 현저히 증가시켰다. Experiments were conducted to determine the effects of plant growth regulators on in vitro flowering and micropropagation of Gentiana scabra Bunge which had been used the cut flower, pot flower ornamental and medicinal plants. Flower bud formation was affected by GA$_{3}$ and kinetin. The optimum concentrations for flower bud formation was observed at 0.5 mg/l kinetin and GA$_{3}$ , while kinetin was favorable. More flowerings result from the interaction of GA$_{3}$ and kinetin at in a combination of 0.1 mg/l kinetin + o.1 mg/l GA$_{3}$, but the optimum concentration of GA$_{3}$ and kinetin was decreased. All concentrations of kinetin with 0.1 mg/l GA$_{3}$ or O mg/l GA$_{3}$ + 0.5 mg/l kientin reduced t (weeks needed for 50% plantlets). The plantlet growth was affected by GA$_{3}$ and kinetin during plantlet culture. More lateral shots and better shoot length per plantlet were obtained as GA$_{3}$ and kinetin concentration were increased up to 1.0 mg/l. The number of per plantlet was greater increased in MS medium containing GA$_{3}$ than kinetin. Interaction was exhibited at lower concentration with 0.5mg/l GA$_{3}$ and kinetin, but not in higher concentration with 1.0 mg/l GA$_{3}$ and kinetin. Higher pod diameter increased seed germination, while lower pod diameter was obtained from abnormal plantlet. MA medium containing 0.5 mg/l GA$_{3}$ significantly increased germination without regard to pod diameter.

코팅의 목적은 기계화 정밀파종하여 파종과 솎음 노력을 절감하는데 있다. 코팅 고형물질의 용적밀도는 dialite, kaolin, talc 및 diatomaceous earth등이 낮았고 기공성도 많았다. 수분보유력이 우수한 고형물질은 bentonite와 dialite였으며, 각각 184% 및 173%의 수분을 보유할 수 있었다. 반면 calcium carbonate, calcium oxide, fly ash등은 수분보유력이 낮은 코팅 고형물질이였다. 코팅 고형물질의 pH는 kaolin, diatomaceous earth, dialite등은 pH가 각각 6.8, 7.6 및 7.4로 중성이었으나, limestone, calcium oxide, bentonite 등은 pH가 12.8, 13 및 10으로 강알카리였다. 전기전도도는 강알카리인 limestone, calcium oxide에서 높았다. 코팅 고형물질을 EDS로 분석한 결과 Talc는 주성분이 Si(71%)였고 Mg도 29% 함유하였다. 반면 calcium carbonate는 주성분이 Ca(66.6%)였으며, 그외에 Si(22.9%)와 Mg(10.5)를 함유하였다. 종자의 입단형성은 talc, talc + calcium carbonate 혼합물질, diatomaceous earth 등에서 우수하였다. 코팅종자의 경도는 bentonite 코팅은 경도가 가장 높았다. 코팅층의 붕괴 형태는 diatomaceous earth, talc, limestone, zeolite, 및 fly ash는 파열형이었고, 용해형은 calcium carbonate와 calcium oxide등이였다. 반면 bentonite와 vermiculite는 팽창형이었다. 코팅층의 분해는 diatomaeous earth가 가장 빨랐고 calcium carbonate, kaolin등도 비교적 빠른 고형물질이였다. 코팅배율이 높아지면 발아속도(T50)은 지연되었다. 당근종자에서 적정 코팅배율은 19.0배가 좋았다. The purpose of seed coating is to enlarge the seed size, to enable the mechanical planting, and to save the labor for thinning. Bulk density of coating particulate matters in dialite, kaolin, talc and diatiomaceous earth was low and the porosity was high. The particulate matters with high water holding capacity were bentonite and dialite, and they were 184% and 173%, respectively. On the meanwhile, those with low water holding capacity were calcium carbonate, calcium oxide, and fly ash. The pH of kaolin, diatomaceous earth, and dialite were 6.8, 7.6, and 7.4, and that of limestone, calcium oxide, and bentonite were 12.8, 13.0, and 10.0, respectively. High electro-conductivity was shown in limestone and calcium oxide. When we analyzed with EDS, the main component of talc was Si(71.0%) and Mg(29.0%), and that of calcium carbonate was Ca(66.6%), Si(22.9%), and Mg(10.5%). High granulation capacity was observed from talc, talc + calcium carbonate mixture, and diatomaceous earth, Seeds coated with bentonite showed the highest hardness. The dissolving type of seeds coated with diatomaceous earth, talc, limestone, zeolite, and fly ash showed split type, and those with calcium carbonate and calcium oxide showed melt type. However, those with bentonite and vermiculite showed swell type. Diatomaceous earth took the shortest dissolving time of coating, followed by calcium carbonate and kaolin. The germination speed (T50 ) was delayed as the size of coated seeds was bigger. The optimum size of coating was 19.0 ratio in carrot.

Although medical science was rapidly developed followed by the development of modern civilization and culture, human beings are suffering from various physical and mental diseases due to the environmental and social factors, and these kinds of problems are facing with the limits which can not be solved with modern medical technology. Recently, horticultural therapy as a field of substitutive medical science to overcome the aforementioned limits becomes the center of public interest, and is a newly hot area although it is not technically fixed. Therefore, it is needed to establish the program developed as a part of horticulture under our circumstances through the case collection of foreign countries. There is a lot of changes to the public as a result of healing people followed by the simple concept to use the horticulture as a therapy for sufferers, although horticulture was simply considered as a means of living or a hobby until now. There is a good example such as flowers or herbs. It can stimulate the public attention for flowers or herbs as using as horticultural therapy, not only for growing flowers or herbs. For the selection of a herb as a horticultural therapy program, it should be called as a medicinal or aromatic Plant which is familiar term for the public in stead of herb. Also, popular plants should be used for the therapy, especially wild herbs which can be easily found our environs, and it should be needed to research on those plants.
