  • 도시화로 인해 불투수층의 증가는 강우시 유출을 증가시켜 물순환을 왜곡시키고 다양한 오염물질을 수계로 배출시켜 수질악화 및 수생태계를 훼손시킨다. 이러한 환경 수문학적 문제를 해결하기 위하여 침투, 여과, 저류 등의 물리적 기작, 식생 및 토양의 생물학적 기작을 이용한 LID 기술을 적용하고 있다. LID 시설에 적용되는 식물은 심미적, 경관성을 증대시켜주나, 다량의 오염물질이 유입될 경우 일부 식물의 고사를 유발한다. 따라서 본 연구는 LID 시설내 식물 체내 중금속 농도를 파악하고자 수행하였다. 본 연구는 지붕 강우유출수를 처리를 위해 설치된 LID 시설(침투화분) 모니터링 대상 지점으로 선정하였으며, 패랭이(Dianthus chinensis)와 조팝나무(Spiraea fritschiana)가 식재되어있다. LID 시설 내 식재된 식물과의 비교를 위해 패랭이와 조팝나무가 식재된 화단을 각각 대조군으로 선정하였다. 패랭이는 잎과 뿌리, 조팝나무는 줄기와 잔가지로 구분하여 체내 중금속 함량에 대해 분석을 수행하였다. 중금속 분석은 토질오염공정시험기준에 의해 Fe, Ni, Zn, As를 분석하였다. 연구결과, LID 시설에 적용된 식생과 대조군 식생의 체내 Fe 농도는 패랭이(1176.9~3804.6mg/kg), 조팝나무(218.4~342.5mg/kg)이며, Ni의 경우 패랭이(13.3~21.4mg/kg), 조팝나무(7.2~12.5mg/kg) Zn은 패랭이(33.6~160.5mg/kg), 조팝나무(46.1~243.2mg/kg), As는 패랭이(7.3~37.3mg/kg), 조팝나무(1.9~8.7mg/kg)로 대조군에 비해 유사하거나 높은 값을 보이는 것으로 분석되었다. 또한, LID 시설에 식재된 조팝나무는 대조군에 비해 줄기는 약 26배, 잔가지 19배 이상 높은 농도를 보이는 것으로 나타났으나, 중금속 농도의 차이는 식물의 중금속 흡수 혹은 토양의 중금속 흡착능력이 토양의 종류, 특성에 따라 다를 수 있기 때문에 모니터링 환경에 따라 편차가 존재할 것으로 판단된다.

  • This study was conducted to develop the suitable plant mat for garden mum. The results about growth 2 months after cutting of garden mum (Dendranthema grandiflorum 'White Miri') under 6 different plant-mat treatments using coir tape were as follows. The majorities of cuttings were withered under treatments of non-soiled 15 mm thick mat (C treatment). On the other hand, the same thick mat having a hole filled with soil 3 mm in diameter (D treatment) and the 30 mm thick mat having a hole filled with soil (F treatment) showed the best growth results. The survival rates of treatments D and F showed the higher rates of 100 and 90%, respectively than those of respective 56.3 and 20% of two layers without medium (A treatments) and C treatment having respective 10 and 15 mm thick non-soiled mats. The plant height showing the similar tendency with the result of the survival rate was shown with the lower value of 7.97 and 7.15 cm, respectively under treatments A and C, compared with the higher value of 9.74 and 9.80 cm respectively under treatments D and F. For flower gardening, it is better to adopt treatment D based on the our investigational results that treatment D required less soil than treatment F and had no trouble with forming adventitious roots for manufacturing mats and effective transferring.

  • This study was conducted to investigate the effect of simulated acid rain (SAR) on growth and antioxidant system in french marigold (Tagetes patula L.). Plants were subjected to four levels of SAR (pH 5.6, 4.0, 3.0, 2.0) in the growth chambers for 2 weeks. SAR decreased both plant height and plant dry weight of french marigold. As the pH levels decreased from 5.6 to 2.0, the content of MDA highly increased linearly. The ratios of dehydroascorbate/ascorbate and oxidized glutathione/reduced glutathione were significantly increased with decreasing pH levels. The enzyme (superoxide dismutase, ascorbate peroxidase etc.) activities of the plant affected by SAR were increased as the pH decreased. Based on the results, SAR caused oxidative stress in french marigold and resulted in significant reduction in plant growth. Biochemical protection responses might be activated to prevent the plant from damaging effects of oxidative stress generated in SAR.

  • In 2002, a stem rot disease was found on Pansy (Viola tricolor) in several road-side flower beds in Jinju City, Gyeongnam province, Korea. The typical symptoms of the disease were stem rot, crown rot, wilt or blight. Upper parts of the infected stems were mostly blighted. White mycelial mats were spread over lesions and the sclerotia were farmed on the stems near soil line. The sclerotia was globoid or irregular in shape, 1.3~4.2 mm in size, and brown in color, The optimum temperature for fungal growth was about 3$0^{\circ}C$. The typical clamp connections were found in the hyphae of the fungus grown on PDA, and hyphal diameter was 3.9~10.4 ${\mu}{\textrm}{m}$. On the basis of mycological characteristics and pathogenecity test on host plants, the fungus was identified as Sclerotium rolfsii. This is the first report on the stem rot of Viola tricolor caused by Sclerotium rolfsii in Korea.

  • This study analyzed the perceptions of teachers to establish the direction for managing the space outside an elementary school. Satisfaction with outdoor school spaces is influenced by the satisfaction with tree and flower plantation and outdoor rest spaces. This study found that the longer the working years of a teacher, the higher their awareness of the importance and necessity of outdoor spaces in the school. Respondents emphasized the lack of manpower and budget, as well as the indifference of the administration as hindrances to the management of outdoor spaces in the school. The outdoor space in the school should include a secure play area, plant education space, class practice spaces, and a rest area. Furthermore, the space outside the elementary school should support learning, playing, and resting. To this end, facilities such as benches, pergolas, outdoor classrooms, ecological ponds, farms, and flower beds should be provided. In an outdoor space, plants featured in textbooks, seasonal plants, and those that provide shade can be planted along with labels to provide information and thereby promote learning. The teachers expected that the management of the external space will have an educational and emotional effect on students. In response to the innovation of the school spaces, it is necessary to continuously manage the external spaces to achieve educational and emotional effects by organically connecting the outdoor spaces with the indoor space. For this purpose, it is required to provide support for securing budgets and manpower, and to introduce relevant policies.

  • The purpose of this study is, focusing on the ancient paintings and literatures, by examining Flowering Plants and drawing their cultivating methods, to provide a ground of utilizing them on the modern landscaping. In the scope and method of this study, 766 pieces of ancient paintings(6 garden paintings and 760 folk paintings) which were available and had value as literatures, and 8 of ancient literatures were intensively examined. Main results extracted from them are as follows. First, the most frequently used Flowering Plants in Joseon Dynasty were Prunus mume, pbyllostachys, Nelumbo nucifera, Chrysanthemum morifolium, Musa basjoo, Rosa spp., Rhododendron mucronulatum, Paeonia lactiflora, which appeared 11 times to 16 times in total. Next frequently(4 times to 8 times) used Flowering Plants were Gardenia jasminoides, Punica granatum(8 times), Dianthus chinensis, Vitis vinifera(7 times), Orchidaceae, Syringa velutina, Impatiens balsamina, Hemerocallis fulva, Celosia cristata, Hibiscus Syriacus, Rhododendron indicum(6 times), Rhododendron, Rhododendron obutusum, Acorus calamus, Althaea rosea, Kerria japonica, Citrus junos(5 times), Hibiscus mutabilis, Lychnis cognata, Calendula officnalis, Begonia rex., Helianthus annuus, Papaver spp., Narcissus tazetta, Daphne odora, Hosta plantaginea(4 times). Second, usage of the Flowering Plants in Joseon Dynasty can be divided into character building and horticulture for pleasure through positive, scientific approach attempt. It suggests that there might have been classes in the use of them and we can estimate which plants were particularly preferred. Third, in the symbolicity of the usage of Flowering Plants, it can be divided into three parts: The case of representing integrity, gentleman, honesty and nobility and the thought of loyalty and filial piety under the influence of Confucianism. The case of representing Taoism's thought of hermit and perennial youth and long life. The case of representing wish on wealth and prosperity. So if we make a good use of it, we may draw a meaning of cultivation of Flowering Plants from it. This is your target audience or the good luck to all he plants is aimed at, you can see the occurred. Fourth, the Joseon Dynasty was the use of flowering plants are the line of rain wanted to be more consistent with the spirit world. This is shown as a symbol of their ancestors. Joseon Dynasty was used, resulting in a kind of flowering plant and is not a subjective judgement criteria A psychological approach to the side when interpreting the Joseon Dynasty flowering plants to take advantage of the landscape of the area will widen in scope.
