백양꽃(Lycoris koreana)이 속해 있는 상사화속(Lycoris)은 종간 잡종이 쉽게 일어나 많은 자연교잡종을 가지고 있어 식물의 종분화와 진화를 연구하는데 흥미로운 분류군이다. 그러나 이런 사유로 명백한 분류학적 차이가 있음에도 불구하고 대상종의 분류학적 위치의 설정에 문제가 발생되어 계급의 설정에 혼란을 가져오기도 한다. 특히 한국산 상사화속의 종 분류는 그동안 많은 형태학적, 분계학적, 화분학적, 세포학적, 분자생물학적 연구가 이루어져 있음에도 아직도 도감과 많은 문헌에서 오류와 오동정의 문제점을 가지고 있다. 특히 백양꽃에 대하여서는 Nakai에 의해 신종으로 설정된 이래 일본에 분포하는 동 속 식물과의 관계 분석의 오류로 계급의 설정에 현재까지 다양한 문제가 발생되고 있다. 백양꽃은 전라남도 백양산에 분포하고, 포가 자주색이고, 꽃의 크기가 작으며, 화사와 화주가 적색 또는 암적색인 특징으로 Nakai에 의해 신종으로 설정되었다. 이후 Nakai와 Lee는 L. koreana 가 한국에만 분포하는 것으로 보고 한국 특산종으로 취급하였다. 그러나 백양꽃의 실체에 대하여 많은 논의가 있었으나 Lee and Oh는 L. radiata로 동정하였고, Yang은 L. koreana는 한국에 분포하지 않고 L. sanguinea만이 분포하는 것으로 보고하였다. Koyama는 L. sanginea에 대하여 L. sanguinea와 L. kuishiana를 비교하여 수술이 화관 밖으로 돌출되어 있는 점 외에는 L. koreana와 차이가 없음을 들어 각각 L. sanguinea var. sanguinea, L. sanguinea var. kuishiana 그리고 L. sanguinea var. koreana로 재설정 하였고 이는 한국과 일본학자들에 의해서도 거의 받아들여지고 있으나 본 연구를 통하여 L. koreana의 종(species)으로의 계급 부여와 한국특산식물 설정의 타당한 결과를 도출하였다.

본 연구는 국내에 자생하는 자원식물들의 살초활성을 조사하여 식물생장억제물질을 활용한 환경친화형 제초제 개발에 요구되는 기초 자료를 확보하기 위해 수행되었다. 국내 자생 식물 101종을 식물체 부위별로 나누어 MeOH로 추출하여 획득된 시료 129점에 대해 돌피(Echinocholoa crus-galli P.B. var. formosensis Ohwi)를 이용한 살초활성 검정을 실시하였다. 시료를 소량의 methanol로 녹여 직경 5.5cm petri dish 상의 Whatman No. 2 여지에 균일하게 흡착시킨 후, fume hood 내에서 용매를 제거하고 1mL의 증류수를 첨가하였다. 돌피 종자를 15립씩 3반복으로 파종하여 $28^{\circ}C$, 5,000lux의 growth chamber에 치상하고, 7일 후 시험구 당 균일하게 자란 10개의 유묘를 선발해 초장 및 근장을 조사하였으며, 살초활성 평가를 위해 대조구 개체의 초장과 근장에 대한 생장억제율을 산출하였다. $1,000{\mu}g/mL$ 농도에서 101종 129점 MeOH 추출물들의 돌피 유묘 뿌리 생장에 대한 억제율을 조사한 결과, 80% 이상을 나타낸 식물 시료는 가죽나무 줄기, 누린내풀 지상부, 단풍취 뿌리, 두릅나무 지상부, 백양꽃 전초, 백양꽃 지하부, 병조희풀 경엽부, 산사나무 잎 가지, 삽주 뿌리, 상사화 전초, 상사화 지하부, 석산 뿌리, 애기송이풀 전초 등 17점이었다. 이들 중 90% 이상 고활성을 나타낸 단풍취 뿌리, 두릅나무 지상부, 백양꽃 전초, 상사화 지하부, 석산 뿌리 유래의 추출물에는 새로운 환경친화형 제초제 개발소재로써 활용할 수 있는 살초활성물질들이 함유되어 있는 것으로 생각된다.

Texa of Lycoris in Korea were classified as five species with two varieties and revised taxonomically. Among the examined taxa, five Korean endemic plants were clarified: Lycoris flavescens M. Kim et S. Lee, L. uydoensis M. Kim, L. chejuensis Tae et S. Ko, L. chinensis var. sinuolata Tae et S. Ko, and L. sanguinea var. koreana (Nakai) T. Koyama. It was found that L. flavescens, L. uydoensis, and L. chejuensis were the natural hybrids between taxa of M+T karyotype and A karyotype. A specimen collected on Aug. 20, 1987 by M. Kim was designated as a holotype of Lycoris flavescens M. Kim et S. Lee. Lycoris flavescens var. uydoensis was ranked up to L. uydoensis. A key to all species including descriptions of each taxon was provided.

Within the scope that does not interfere with the performance of basic duty, the military has been actively supporting the national policy for the conservation of the natural environment in accordance with the "military environmental protection guidelines". Since there is a lack of information regarding inhabitation for wild fauna and flora, field investigations of the natural environment at Jinhae local unit were performed three times in 2003. As a result of the investigation, lycoris sanguinea as flora, marten, otter, and leopard cat as mammalia, and accipiter soloensis, accipiter gentilis schvedow, accipiter gularis, buteo hemilasius, falco tinnunculus and terpsiphone atrocaudata as bird were confirmed to inhabit. For the conservation of the natural ecosystem, the expansion of research for natural ecosystems within the military unit is required. Additionally, environmental pollution can be prevented through the proper maintenance of basic environmental facilities including sewage treatment facilities, soil pollution control facilities, and waste storage facilities. In cooperation with local governments and private organizations, the natural cleansing action and sustainable wildlife conservation should be expanded.

This study examined the status of the vegetation around Gangcheonsan provincial park located in Sunchang-gun in Jeollabuk-do and Damyang-gun in Jeollanam-do from June 4 to October 12, 2011. Gangcheonsan vegetation was arranged 9 plant communities in accordance with data of 28 releves. Major forest vegetation included Quercus variabilis communityand Quercus variabilis-Quercus serrata community, Pinus densiflora community, and Pinus densiflora-Quercus variabilis community (evergreen coniferous forest in all), and Phyllostachys nigra var. henonis community (plantation). Wetland vegetation included Salix gracilistyla community (riverbank forests), Phragmites japonica community, and Polygonia thunbergii community. Gangcheonsan Provincial Park has beautiful scenery that is in harmony with fantastically-shaped rocks, waterfalls, and valleys and conserves a specific plant community habitat distributed through the forest wetlands including its valleys. It is necessary to conduct long-term monitoring with its focus on Pinus densiflora community, Lycoris koreana community, and Lycoris squamigera community in the provincial park to grasp the characteristics of ecological inhabit changes in major communities and provide active methods for conservation, restoration, and publicity.
