  • This study was carried out to examine vascular plants and invasive alien plants in Gyodong Island, located at the northwestern Civilian Control Line (CCL) of Ganghwa-gun, Incheon, and to use them as basic data for systematic management of identified plants and establishing biodiversity conservation measures. The survey was conducted 13 times from April 2019 to August 2021. The vascularflora in Gyodong Island was identified as 109 families, 378 genera, 641 species, 15 subspecies, 49 variants, 8 forma, a total of 713 taxa. This was found to be about 15.36% of the total 4,641 taxa of vascular plants in Korea. The northern linage plants on the Korean Peninsula appearing in the Gyodong Island area were identified in 83 classification groups, including Red-based leaf edge (Carex erythrobasis H.Lev. & Vaniot). Korea endemic plants were identified as 16 taxa such as Seoul wild-ginger [Asarum heterotropoides var. seoulense (Nakai) Kitag.], and a total of 20 taxa of rare plants designated by IUCN were observed, including the endangered grade Beardless iris (Iris ruthenica Ker Gawl.). Floristic target species were classified with a total of 99 taxa. For V grade, Beardless iris 1 taxon was found. and also IV grade and III grade were identified in 8 taxa and 20 taxa respectively. The invasive alien plants identified as 75 taxa, such as Verbesina alternifolia (L.) Britton ex Kearney. The naturalization rate was 10.51%, and the urbanization index was calculated as 23.29%. Since large-scale construction has been currently underway on Hwagae Mt. in Gyodong Island as the target of survey area, the influx of invasive plants will be expected to promote. Therefore, it is urgent to establish in-situ protection and conservation measures for notable plants such as Beardless iris and Water smartweed [Persicaria amphibia (L.) S.F.Gray].

  • This study surveyed the Mt. Teomo·Hyeolgu and surrounding areas in Ganghwa Island, located in Ganghwa-gun, Incheon, to identify vascular flora and alien plants to be used as basic data for systematic management of the remarkable plants and biodiversity conservation. The survey was carried out 13 times from March 2019 to October 2020. The identified vascular flora of Mt.Teomo·Hyeolgu was 101 families, 321 genera, 517 species, 13 subspecies, 38 varieties, 5 forms, and 573 taxa. They accounted for about 12.35% of a total of 4,641 taxa of vascular plants in Korea. The identified Northern lineage plants, endemic plants, and rare plants on the Korean Peninsula as designated by IUCN were 68 taxa, 10 taxa, and 9 taxa, respectively. 69 taxa were classified as floristic target species. Three taxa, including Maui sedge [Carex thunbergii var. appendiculata (Trautv. & C.A.Mey.) Ohwi] were identified s Class IV and 14 taxa, including Violet Stanavoi clematis (Clematis fusca var. violacea Maxim.) were identified as Class III. The naturalized plants that appeared in the study site were 63 taxa, including daisy fleabane [Erigeron annuus(L.) Pers.], common ragweed [Ambrosia artemisiifoliaL.] and Canadian fleabane [Conyza canadensis(L.) Cronquist]. The above three species were found to have spread throughout Ganghwa Island and surrounding areas such as Seokmo Island, Gyodong Island, and Gimpo city. As introduced disturbing plants like prickly lettuce [Lactuca scariola L.], bur cucumber [Sicyos angulatus L.] and field dock [Rumex acetosella L.] have been newly reported in the Mt. Teomo·Hyeolgu area, mid- to long-term conservation measures should be established for native plants, such as remarkable plants, and also management measures like physical removal should be prepared at an early stage.

The numbers of vascular plants were summarized as 282 taxa including 81 families, 201 genera, 252 species, 3 subspecies, 22 varieties and 5 forms. The Raunkiaer life forms are analyzed in hemicryptophytes were 66 taxa (23.4%) in dormancy form, non-clonal growth ($R_5$) were 160 taxa (56.7%) in propagation form of radicoid form, having no special modification for dissemination ($D_4$) were 197 taxa (48.6%) in propagation form of disseminule form, erect form (e) were 117 taxa (41.5%) in growth form. The halophytes were 23 taxa including Salsola collina, Asparagus oligoclonos and so on. The rare plants were 7 taxa including Pyrrosia hastata (VU), Senecio nemorensis (VU) and so on. The Korean endemic plants were 5 taxa including Hepatica insularis, Lespedeza maritima and so on. In the specific plants by floristic region were 38 taxa, a degree I were 23 taxa (Dictamnus dasycarpus, Vitex rotundifolia and so on), 6 taxa of a degree II (Morus cathayana, Euphorbia esula and so on), 8 taxa of a degree III (Pyrrosia hastata, Rhodotypos scandens and so on), Senecio nemorensis of a degree V and degree IV were not found. The naturalized plants were 17 taxa including Robinia pseudoacacia, Bromus tectorumand so on. Of those Ambrosia artemisiifolia is a invasive alien plants. Naturalization rate (NR) was 6.0% of all 282 taxa of vascular plants and urbanization index (UI) was 5.3% of all 321 taxa of naturalized plants. Gulup-do and adjacent Baega-do were locally investigated field work and it summarizes the results of a total of 41 islands literature in Ongjin-gun and Ganghwa-gun, Incheon including uninhabited islands, Baengnyeong-do, Daecheong-do and so on. The average number of species were each analyzed in about 89 taxa, rare plants are about 2 taxa, endemic plants are about 1 taxa, naturalized plants are about 4 taxa. This study was the comparison of the flora and literature distribution case that the Gulup-do maintain the naturalness and continuously conducted to explore the future conservation measures the adjacent islands.

  • The great part of the traditional knowledge on ethnobotanical plants and their uses is gradually vanishing due to industrialization, therefore ethnobotanical studies that explore and preserve the knowledge are in urgent needed before the knowledge are lost ever. This study was conducted to record and conserve the traditional knowledge of botanical taxa in Korea from 2006 to 2014. According to the survey results, derived from 17,328 sheets of 1,771 residents at 868 places, the ethnobotanical plants in Korea consisted of a total 924 taxa; 130 families, 493 genera, 813 species, 7 subspecies, 92 varieties and 12 form. Of them, herbs were 619 taxa (67.0%) and woody plants were 305 taxa (33.0%). 707 taxa (76.5%) out of 924 taxa grow wild, 44 taxa (4.8%) were cultivated wild species, 145 taxa (15.7%) were introduced for cultivation, and 28 taxa (3.0%) were naturalized plants. The analysis of usage for 924 taxa showed that the edible use was the highest with 58.9%, followed by medicinal with 26.9%, material with 3.7% and ornamental with 2.3%, respectively. The leaf of plant was the most useful part, followed by stem and root. Quantitative analysis of the ethnobotanical plants in Korea was performed by the basic values of FC, NU and UR, and indices of CI, RFC, RI and CV. As a result, The CI place Artemisia princeps in first position, followed by Aster scaber, Kalopanax septemlobus. The RFC place A. scaber in first position, followed by A. princeps, Aralia elata. The RI place A. princeps in first position, followed by Pinus densiflora, Morus alba. The CV place A. princeps in first position, followed by P. densiflora, K. septemlobus.

  • 토양에 존재하는 진균인 Gliocladium virens는 식물병을 감소 또는 방제할 수 있는 생물학적인 특성에 의하여 G. virens는 지난 수십년간 실용가능성이 큰 생물학적 방제균(또는 길항균)으로 집중적으로 연구되었다. 이 균이 식물병의 발생을 감소시키는 생물적 방제효과는 항생작용, 중복기생, 근권에서의 생존과 집단번식, 뿌리표면에서의 정착 등에 의한 것으로 분류되고 있다. 특히, 항생물질인 gliotoxin, gliovirin, viridin 등은 Rhizoctonia solani 및/또는 Pythium spp. 등에 항생효과가 뚜렷하고, 식물병의 발생과 직접적인 상관관계를 나타내고 있어 G. virens의 식물병의 방제에 관련된 중요한 작용기작으로 제시되어 있다. 또한, 근권에서 이균의 생존과 집단증식 및 뿌리표면에서의 정착은 식물병의 방제와 상관관계를 나타낼 수 있는 중요한 작용기작으로 제시되고 있다. 그러나 이균이 R. solani 등에 기생하는 현상은 식물병의 생물적 방제의 직접적인 연관관계를 나타내고 있지 않다. G. virens을 이용의 생물적 방제효과를 증진시키기 위한 방법으로 다음과 같은 두 가지 방법을 들 수 있다. 첫째, 길항효과가 높은 G. virens 균주를 선발하기 위하여 여러 종류의 토양에서 길항력이 높은 G. virens의 선발이 지난 수십년간 진행되고 있다. 또한, 특정 길항효과를 발현하는 유전자를 G. virens의 염색체에 도입하고 이를 발현시킴으로써 생물적 방제효과를 증진시키는 것으로 이러한 방법은 1980년 후반부터 진행되고 있다. 둘째, G. virens의 길항효과가 최대의 효율로 발현될 수 있도록 최적의 미세환경을 갖추고 있으며 농민이 편리하게 사용할 수 있는 G. virens의 운송매체의 개발이 중요하다. 운송매체의 개발에 의한 'Glioguard'는 G. virens의 포자를 alginate 입자에 제형화한 것으로서 미국에서 시판되고 있다. Aldicarb, metalaxyl, atrazine 등의 농약을 분해할 수 있는 능력은 G. virens의 다른 생물적 특성중의 하나이다. 특히, parathion을 분해할 수 있는 Flavobacterium sp.의 유전자(opd)가 G. virens의 염색체에 도입되여 발현될 수 있는 방법이 제시되었으며, 이는 G. virens을 이용한 토양에서의 특정한 농약의 분해효율을 증진시킬수 있는 가능성을 제시한 것이다. 그러나, G. virens를 이용한 농약의 생물적 분해에 관한 연구는 기초단계로 평가되고 있으며, 포장에서 이를 실용화하기 위해서는 향후 지속적인 연구가 필요하다.
