  • To search for myrmecochorous plant species in Korea and their diaspore characteristics, the flowering and fruiting of herb species, collectiong their fruits and diaspores, and the related ant species were studied from April to September 2011. Twenty-four herb species growing in Korea prove myrmecochorous (seed attached elaiosome) plants. Elaiosomes of 24 herb species vary considerably in shape and size. Major ant species transporting the diaspore of myrmecochorous plants are Formica japonica, Lasius alienus, Tetramorium tsushimae, Temnothorax koreanus, Lasius japonicus, but Camponotus japonicus and Paratrechina sakurae do not transport the diaspores. This study found out that mutualism between myrmecochorous plants and ants is carried out in Korea. Further study on the myrmecochorous plant and related ant species, cafeteria experiments should be needed.

  • 한국 특산 식물인 미선나무 (Abeliophyllum distichum)는 IUCN Red List의 EN (위기종) 등급에 지정되 어 보호받아 왔다. 미선나무는 국내 자생지 6곳을 포함하는 13개의 서식지에서 생육되고 있다고 알려져 있다. 2017년 이후, 국내에서는 지속적인 보전과 관리하에 법정보호종에서 해제되어 멸종위기종 복원 성 공 사례의 귀감이 되었으나 국내를 제외하면 미선나무의 활용은 아직 어려운 현실이다. 미선나무는 1속 1종이지만 종 내에서 다양성이 존재한다. 꽃의 형태적 특징에 따른 다양한 분류가 이루어지며, 옥황1호을 포함한 분홍, 상아, 연녹색, 흰색 등으로 구분된다. 유전체 연구 및 성분 분석을 통해, 각 표현형마다 유전 정보와 유효 성분의 차이가 존재한다는 것이 알려졌다. 활용 가치를 높이려면, 유전적으로 안정되고 표준화가 가능한 원료가 필요하며, 이는 신품종을 이용하거나 새로운 개발이 필요하다는 것을 내포한다. 일반 식품으로의 활용은 어려우나 기능성 화장품의 원료 등으로 활용되고 있으며, 이러한 활용들은 미선나무의 높은 활용 가치를 투영한다. 활용 가치 평가를 위해 수행된 DNA 손상, 멜라닌 생합성, 항염증, 항산화, 항암 억제 등의 연구를 통해 다양한 약리학적 효능을 가진다는 결과들이 도출되었고, 많은 문헌들이 그 근거를 뒷받침한다. 또한, 유효 성분의 합성경로를 재정립하고 RNA 분석을 통해 그 양상을 예측하기 위한 연구가 진행 중에 있다. 미선나무에서 유래한 식물조직 배양체인 callus의 유도 및 배양이 진행되고 있으며, 옥황1호 유래 callus를 활용하여 다양한 연구를 수행하고 있다. 앞서 언급한 미선나무 연구 및 개발에 대한 한계를 파악하고, 천연 식물 자원으로의 미선나무에 대한 지속적인 관심과 지원을 통해 나고야의정서에 대응하는 전략적 접근이 필요하다.

  • DMZ 일원은 정전협정으로 비무장지대(DMZ: Demilitarized Zone)가 설정된 이래 민간인의 출입이 엄격히 금지된 채로 외부의 간섭에서 벗어난 독보적 공간으로 보전되어 오고 있다. 하지만 일부 지역은 자연재해 및 군사적 목적으로 훼손되어 생태적으로 교란된 지역이 발생하여 생태적 건강성이 저하되고 있다. 무엇보다 군사분계선 남쪽 2km에 설치된 남방한계선은 군사적 목적에 따라 시계확보를 위해 불모지작전을 수행하여 생태적 교란 및 토양침식에 의해 생태계가 열악한 실정이다. DMZ 내 생태교란지 식물복원 연구는 DMZ내 생태교란지를 하나의 특수한 생태계로 간주하여, 향후 DMZ내 생태교란지에 특화된 식생복원 체계를 마련하는데 그 목적이 있다. 이에 본 연구에서는 DMZ 155마일(248km)에 대해서 위성영상분석을 수행하여 생태교란지 유형화분류 연구를 수행하여 7개 유형(저지대초지, 서부저지대산지, 저습지 및 수공간 지역 등)으로 분류하였다. 또한 DMZ 생태교란지에 적합한 식물종 선정을 위하여 DMZ 전역을 대상으로 식물상 조사를 실시하여, 분포가 확인된 종을 대상으로 도입 가능종의 검토, 종자 수집 및 채종원 조성을 실시하였다. 추후 DMZ 생태교란지 식물복원에 적합한 공법연구를 수행하고자 한다. 시계확보를 위해 수행되는 불모지 작전에 적합한 종의 선정, 선정된 종을 대상으로 유사환경 조성에 따른 공법 적용, 적용된 공법에 따른 관리 방안 연구를 함께 수행하고자 한다. 본 연구를 통해 DMZ 일원에 특화된 공법개발이 이루어진다면 불모지 작전 및 관리 최소화가 이루어지고, 무엇보다 우리나라 종자 및 야생화 산업의 활성화와 현재 파편화 되어 있는 생태축이 하나의 축으로 연결 될 것이라고 기대해 본다.

  • A total of 10 islands (Kumodo and Komundo in Yeosu City; Oinarodo in Goheung County; Chongsando, Soando, and Pogildo in Wando County; Chodo in Jindo County; Uido, Huksando, and Hongdo in Shinan County) were surveyed to confirm distribution of naturalized plants from June 2006 to December 2008. A total of 100 naturalized plants taxa from 25 families were recorded. The highest number of naturalized plant species (82 taxa) was recorded on Oinarodo, while the lowest number was recorded on Hongdo (42 taxa) and on Uido (34 taxa). A total of 26 naturalized species taxa (such as Dactylis glomerata, Lolium perenne, Bromus unioloides, Rumex obtusifolius, Chenopodium album, Phytolacca americana, Barbarea vulgaris, Lepidium apetalum, Robinia pseudo-acacia, Trifolium repens, Erigeron annuus, Erigeron canadensis, Senecio vulgaris, Xanthium strumarium) was recorded in all study areas. Distribution of naturalized plants were categorized into 7 habitat types based on ecological traits: afforested land, beach, port, and vacant land, road boundary, road cut and slope area, waste arable land, landfill area, and wetland. Systematic management is required to conserve unique landscape, species diversity, vegetation and ecosystem of Dadohae National Park. In order to manage the naturalized plants in Dadohae National Park, basic surveys are most needed to understand distribution and dispersal of naturalized plants communities based on ecological features of each habitat type.

  • This study was executed to find out how to improve on the planting and use of the plants in Kangweon- Do by surveying the planting areas -gardens, parks, streets, schools, etc. - in five cities of this province, and to select available native plants by surveying the main mountains in this province. The results are as follows ; 1. The species number within surrey areas was 319 species. and the species of which planting frequency was very high were Hibiscus syriacus, Juniperus chinensis, Buxus microphylla v. koreana, etc.. 2. The species number of school trees and flowers of 202 schools in Kangweon-Do were 33 species, 32 species respectively. and the species of school trees and flowers that showed the highest preference were Juniperus chinensis, Forsythia koreana each. 3. The species number of flowers and trees designated in 22 City and Keun were 14 species, 7 species respectively, and the species of flowers and trees that presented the highest designation frequency were Rhododendron schlippenbachii, Ginkgo biloba each. 4. The street trees planted along the main streets in Kangweon-Do were 18 species and 84,939 individuals, and the ratio of Populus alba${\times}$glandulosa was the highest among occurrence individuals. 5, As for the composition ratios of life forms of plants within survey areas, the ratio of deciduous broad-leaved tree was the highest as about 56% and that of deciduous coniferous tree was the lowest as about 1.6%. The ratios of native species versus exotic were 43 : 57 6. Through these results, it was thought that the diversification of planing species, the selection of plants suitable to each space and the generalization of use of native species were needed. So 254 plants native to Kangweon-Do were presented to correspond to these requirements.

  • We investigated the flora of Imja-do(Isl.), an island of the Shinan archipelago, located in Imja-myeon, Shinan-gun, Jollanamo-do and discussed the vascular plants found there. Twenty-four separate field trips (100days) were completed from August of 1997 to October of 2009. As a result, we identified the distribution of 526 taxa in Imja-do(Isl.), comprising 112 families, 331 genera, 463 species, 1 subspecies, 60 varieties, and 2 forms. There are a total of 78 taxa of floristic regional indicator plants and one taxon of level II endangered species, Millettia japonica, as designated by the Korean Ministry of the Environment. The floristic regional indicator plants are as follows; four taxa of level V such as Utricularia bifida, two taxa of level IV such as Cladium chinense, 14 taxa of level III such as Aletris spicata, three taxa of level II, and 55 taxa of level I. In addition, one endangered species (EN), Nymphoides coreana, five vulnerable species (VU),such as Ilex cornuta, and three near-threatened species (NT) such as Utricula riaracemosa, were found in the investigated area. The plants of Imja-do(Isl.) are classified into four types based on the plant geographical origin, as follows: 1) boreal plants advancing southward in a glacial period, 2) temperate plants spreading eastward from the Himalayas and China to Japan passing through the south coast of Korea, 3) subtropical plants, and 4) indigenously developed endemic species of the warm-temperate region of East Asia.
