정서적 안정과 휴식에 효과적이며, 공기 정화 등 기능성을 가진 관엽식물에 대한 수요가 증가하고 있으나, 관엽식물에 피해를 유발할 수 있는 식물기생선충에 대한 연구는 전무한 실정이다. 본 연구는 국내 판매되고 있는 관엽식물에서 발생하는 식물기생선충의 검출 여부와 밀도를 파악하고자 관엽식물과 작물재배지에 대해 2022년 7월부터 12월까지 모니터링을 수행하였다. 415개의 관엽식물과 국내 24개 차나무 및 22개 감귤재배지의 식물기생선충을 조사하였다. 관엽식물 내 식물기생선충 조사 결과, 뿌리썩이선충이 가장 많이 검출되었으며, 잎선충, 뿌리혹선충, 침선충이 확인되었다. 차나무재배지에서는 나선선충, 씨스트선충, 뿌리혹선충, 뿌리썩이선충이 검출되었고, 감귤재배지에서는 감귤선충, 주름선충, 뿌리썩이선충, 뿌리혹선충 등이 검출되었다. 관엽식물, 차나무 및 감귤 재배지에서 뿌리썩이선충이 가장 우려되는 식물기생선충이었으나, 뿌리혹선충, 씨스트선충이 일부 검출되어 피해가 우려되므로 온탕침법, 유기농업자재의 사용, 잡초제거 등 식물기생선충의 방제 방법을 재배에 적용하여야 할 것이다.

A survey on ornamental diseases in 2000 and 2001 showed frequent occurrence of blight symptoms on leaves and stems of columbine and bleeding heart in botanical gardens of Gangwon and Chungnam provinces in Korea. A total of 65 isolates of Streptobotrys sp. were obtained from the infected leaves and stems of the two plants. All isolates were identified as Streptobotrys caulophylli based on their morphological and cultural characteristics. Blight symptoms were induced on leaves of the two plants by artificial inoculation with the isolates. This is the first report that S. caulophylli causes leaf and stem blight on columbine and bleeding heart in the world.

This study was performed to investigate the flora and plant resources of Mt. Gamak (537.8 m) from April to October 2007. The collected vascular plants were composed of all 478 taxa including cultivated species, and classified into 410 species, 3 subspecies, 61 varieties, and 4 forms of 284 genera under 94 families. Six taxa of the Korean endemic plants and 4 taxa of the rare and endangered plants were also distributed in this mount. Resource plants were categorized into edible 222, pasturing 208, medicinal 183, stainable 134, ornamental 96, timber 20, fiber 6 and industrial 4 taxa, respectively. Floristic geography of the investigated area was regarded as the boundary between middle parts in floristic pattern of the Korean Peninsula.

Moss is used as an important material in indoor landscaping as well as outdoor landscaping. Moss is vivid green during growth and excellent in ornamental value. But when temperature drops, moss stops growth, turns brown or loses its ornamental value. In the present experiment, for the purpose of classifying native mosses according to the growth response to low temperature, the temperature of the plant growth chamber was set to 15℃/5℃ (16h/8h, day/night) and 5℃ (24h) for 8 weeks using nine native moss species. Thereafter, the temperature of the plant growth chamber was set to 20℃, and then the changes of moss block area and moss color were measured. The changes of moss block area and moss color were measured using a Photoshop program, after each moss block was photographed. As a result, Atrichum undulatum (Hedw.). Beauv., Etodon luridus (Griff.) A. Jaeger, Bachythecium plumosum (Hedw.) Schimp, Plagiomnium cuspidatum (Hedw.) T.J. Kop, and Hypnum plumaeforme Wilson showed a small decrease in moss block area at low temperature, and their recovery were the fastest at 20℃. These three species had higher green values at low temperature compared to other species, and the greenness increased rapidly at 20℃. On the other hand, Atrichum undulatum (Hedw.). Beauv., Marchantia polymorpha L., and Thuidium cymbifolium (Mitt.) A. Jaeger showed the smallest block area at low temperature and the lowest recovery even at 20℃. Their green values also decreased significantly at low temperature, and maintained low green value even at 20℃. These results showed that these three moss species are sensitive to low temperature. The remaining Myuroclada maximowiczii, Plagiomnium cuspidatum, and H. erectiusculum showed moderate responses to low temperature compared to other six species of mosses.

White light and compound light were found to be the ideal light sources for improving the functionality and ornamental value of indoor plants and reducing the cost of maintenance, but because compound light hinders people from recognizing the original color of plants and makes their eyes easily tired, white light was considered the optimal light satisfying all of the ornamental value, economic efficiency and functionality resulting from plant growth. On the other hand, in the results of examining physiological changes before and after treatment on fine dust PM10 and carbon dioxide removal capacity in a closed chamber under an artificial light source, the patterns of carbon dioxide and fine dust removal were similar among the treatment groups according to light condition, but according to plant type, the removal rate per unit leaf area was highest in $Spathiphyllum$ and lowest in $Dieffenbachia$. In the experiment on dust and carbon dioxide removal, the photosynthetic rate was over 2 times higher after the treatment, and the rate increased particularly markedly under compound light and white light, suggesting that the photosynthetic rate of plants increases differently according to light quality. These results show that light quality has a significant effect on the photosynthetic rate of plants, and suggests that plants with a high photosynthetic rate also have a high carbon dioxide and dust removal capacity. In conclusion, the photosynthetic rate of foliage plants increased under white and blue light that affect photosynthesis and the increased photosynthetic rate reduced carbon dioxide and fine dust, and therefore white and compound light were found to be the optimal light sources most functional and economically efficient in improving ornamental value and indoor air quality.

본 연구는 음지에서 잘 자라는 자생 지피식물 선발을 위해 7종의 자생식물을 대상으로 광 조건을 달리하여 생장반응을 조사하였다. 비비추는 자연광의 60% 차광에서 가장 좋은 생장을 보였으며, 맥문동은 90% 차광에서 생육이 매우 좋았다. 관중은 60% 차광에서 생육이 가장 우수 하였으며, 대사초는 40% 차광에서 초장과 초폭이 신장이 좋았고 엽수도 많았다. 비비추, 맥문동, 관중 및 수호초는 차광율이 높을수록 엽록소 함량이 점차 증가되었으며, 맥문동은 완전음지나 자연광에서는 개화되지 않았다.

역사공간의 진정성 제고와 보존관리에 활용될 기초자료 제공을 목적으로 국가지정 문화재인 경상북도 소재 안동 하회마을, 경주 양동마을, 성주 한개마을 등 3개 민속마을의 외래식물 분포현황을 조사 분석한 결과는 아래와 같다. 1. 민속마을의 전체식물상은 127과 430속 614종 5아종 100변종 33품종으로 총 752분류군이 확인되었으며, 그 중에 목본식물은 263분류군(35.0%), 초본식물은 489분류군(65.0%)으로 나타났다. 하회 양동 한개마을의 전체 식물상은 각각 총 534 479 408분류군이 확인되었고, 외래식물률은 30.1 38.2 37.0%로 나타났다. 유형별로는 관상외래식물이 135분류군, 풍치외래식물이 21분류군, 경작외래식물이 64분류군 그리고 귀화외래식물이 80분류군 으로 나타나, 관상외래식물의 비율이 탁월하게 높았다. 마을별로는 하회마을 161분류군(30.1%), 양동마을 183분류군(38.2%), 한개마을 151분류군(37.0%)으로 양동마을에서 가장 높은 비율의 외래식물이 확인되었다. 2. 하회마을내 단위문화재로 지정된 고택 정원에 식재된 관상외래식물은 총 30분류군이고, 옥연정사(8분류군) 양 진당(7) 하동고택(6) 충효당(5) 등의 순으로 외래식물수가 높았으며, 백목련 능소화의 식재율이 탁월하였다. 양동마을에서는 총 51분류군이 관찰되었는데, 두곡고택(16분류군) 수졸당(14) 무첨당(13) 상춘헌고택(12) 등의 순으로 나타났으며, 수국 불두화 상사화 등의 출현율이 높았다. 그리고 한개마을의 관상외래식물은 총 62분류군으 로 진사댁(35분류군), 교리댁(25) 한주종택(20) 하회댁(16) 등의 순이었으며, 골담초 뚝향나무 백목련 불두화 산당화 등의 출현률이 높았다. 3. 정원 외부를 살펴보면 하회마을에서는 만송정 숲 하부에는 환경부 지정 생태계교란식물인 돼지풀이 높은 우점도로 생육하고 있어, 겸암정사 인근의 가시박과 함께 제거대책의 마련이 시급하다. 또한 만송정숲 주변 낙동강 하상으로는 아까시나무림과 양버들군락 등의 풍치외래식물이 하안식생으로 띠숲을 이루고 있다. 양동마을에서는 마을 안길에 자연 발생한 가죽나무군락과 아까시나무와 족제비싸리가 비향토식생경관으로 인지된다. 또한 한개마을 외곽에 산발적으로 분포하는 가죽나무와 아까시나무의 세력 확산이 문제점으로 드러났다. 민속마을 간 발생 외래식물의 유사도는 47.0~48.6%로 이와 같은 이유는 연구대상지가 모두 경상북도에 위치하여 있는 관계로 식물의 생육조건이 유사하며, 관상용으로 판매되는 외래식물이 제한적이기 때문으로 판단됨에 따라 외래식물에 대한 마을별 관리대책과 공통 관리대책의 병행이 요구됨을 암시하였다.

In order to provide a scientific foundation for herb application in landscape, the photographs were taken from the herb landscape in urban green space and sightseeing garden. The questionnaire-based survey was also applied to analyze the cognitive situation of herb. Most investigators love herb, but have a low level of herb; Interviewees' consideration of herb function lie in ornamental, healthcare and medical treatment; The bulk of the visitors think herb landscape is insufficient; Investigators' preferences for herb application forms are landscape edging and combining with stone. We also probe into the optimum allocation form combining herb with landscape elements. When we combine herb with landscape water or landscape architecture, artistic conception and reasonable plant allocation should be considered; When we combine herb with landscape path or garden ornament, reasonable plant disposition and appearance and practical collocation should be thought over; When we combine herb with flower-border, richly colored landscape and reasonable plant allocation should be deliberated on.
