  • 성널수국은 일본 관서지방에 널리 분포하고 있지만, 한반도에서는 제주도에서만 발견되고 있는 멸종위기 식물이다. 본 연구에서는 성널수국에서 총 5개의 microsatellite 유전자좌를 형질화하여 마커를 개발하였다. 유전자좌당 대립유전자수의 범위는 3-27개, 이형접합률의 관측치와 기대치는 각각 0.27-0.86과 0.34-0.91로 나타났다. 본 연구에서 개발된 microsatellite 마커는 성널수국의 유전적 다양성 및 구조, 그리고 유전자 이동을 밝히는데 사용될 수 있을 것이며, 그 결과들은 한국산 성널수국에 대한 효과적인 보전 전략을 제시하는데 일조할 것으로 기대된다.

  • A survey for vesicular-arbuscular mycorrhizae (VAM) occurrence was undertaken in three endangered vegetation sites in the area of Kudankulam atomic power station. Fifteen VAM fungal species were isolated from the root-zone soils of fourteen different plant species. There was a significant correlation observed between the number of spores and of percentage root colonization as exemplified by Phyllanthus niruri and Paspalum vaginatum (450, 95%; 60, 25%). Although VAM species are not known to be strictly site specific, the fact that Acaulospora elegans was observed only in site 1, Glomus pulvinatum in site 2 only, and Gl. intraradices in site 3 only, showed site-specificity in this study. To confirm the infection efficiency, two host plant species in the sites, P. niruri and Eclipta alba, were selected and inoculated in field with three selected VAM fungal spores. Gl. fasciculatum was found to be the most efficient VAM species in percentage root colonization, number of VAM spores, and dry matter content. When the nutrients in roots of P. niruri and E. alba were analyzed, there was higher uptake of K (4.2 and 3.4 times, respectively) and Ca (5.3 and 4.9 times, respectively), the analogues for $^{137}Cs$ and $^{90}Sr$, respectively. From the results, it might be concluded that VAM association helps the plants survive in a disturbed ecosystem and enhances uptake and cycling of radionuclides from the ecosystem.

  • As the importance of biological resources increases, the conservation technology is becoming important for rarities. This study was conducted to establish an efficient cryopreservation conditions for the Deutzia paniculata, endangered plant species, by using both cryopreservation methods of vitrification and encapsulation. As a result, the sucrose pretreatment seed viability showed up to 30.7% in the treatments. The cryoprotectant treatment improved the viability of the seeds, and was found to be excellent in the vitrification method using PVS3. The vitrification method had over 10% higher germination rate than the seeds preserved by encapsulation. In addition, the germination rate showed a significant difference according to the cryopreservation treatment time, and the germination rate of seeds decreased very much as the long time became longer. Plants germinated from preserved seed in liquid nitrogen showed poor growth compared to untreated, and good growth in PVS3 120 minutes. In addition, the growth of germinated plants by liquid nitrogen treatment time was better in the vitrification method. These results are expected to be useful for long-term preservation of D. paniculata, endangered plants.

Based on the list of rare and endangered plants from the Forest Research Institute and the Ministry of Environment, 22 species were recorded in the studied areas: Thuja koraiensis(Cupressaceae), Arisaema heterophyllum(Araceae), Disporum ovale(Liliaceae), Tricyrtis dialata(Liliaceae), Lilium distichum(Liliaceae), Anemone koraiensis(Ranunculaceae), Rodgersia podophylla(Saxifragaceae), Rosa marretii(Rosaceae), Viola diamantica(Violaceae), Viola albida(Violaceae), Echinopanax horridum(Araliaceae), Acanthopanax chiisannensis(Araliaceae), Lysimachia coreana(Prinmulaceae), Syringa velutina var. kamibayashii, Halenia corniculata(Gentianaceae), Partrinia saniculaefolia(Valerianaceae), Adenophora grandiflora(Campanulaceae), Cacalia pseudo-taimingasa(Compositae) Iris odaesanensis(Iridaceae), Leontice microrhyncha(Berberidaceae), Rpdgersia tabularis(Saxifragaceae), and Acanthopanax sentico년(Araliaceae), Among them the four species were recorded from the list of the Ministry of Environment. As most of the species were recorded from the mountain-trails, the long-term habitat monitoring for the species is required .

  • The floristic characteristics and ecological conservation measures for the plant resources of the Mt. Kumjung(801m), Pusan, Korea were discussed. The field works was done for about twenty times in nine major areas from March, 1995 to Octover, 1996. The total number of vascular plants In this area were summarized as 103 families, 312 genera, 493 species and 564 kinds. The fourteen kinds of artificially planted, ten kinds of Korean endemics and twenty-nine kinds of Korean rare and endangered species in the area were revised and compiled in the list. The flora of the area were categorized into the South-coast put of the Korean Region, where the species such as Platycarya strobilacea, Quercug serrata, Eutya japonica, Camellia japonica, Trachelosperm urn asia talcum vu . in termedium, Quercus acu tissima were roles as major floristic components in the Korean Region and endemized in the south-cosat part of Korea. The natural communities such as Pinus thunbergii Community, Quercus mongolica community, Cupinus laxiflora Community, Wistria floribunda Community and swamp vegetation in Bukmun area as well as upland grassland at the summit of Kodangpong were represented for their floristic values in the area. The thirty kinds of medichinal plant, fifteen kinds of ornamental plants and thirteen kinds of edible plants are faced potentially in endangered from the outrageous collections by the local peoples. The action plan for the conservation management of the area which enables sustainable use by the local peoples must have established in the near feature.

  • Iris odesanensis Y.N. Lee is one kind of species among 54 endangered plant species designated by the Ministry of Environment in Korea. It is very rare native plant throughout the country. Therefore, this study was conducted to investigate the native Iris odesanensis in Mt. Naeyon for their distribution and ecological characteristics. They were mostly distributed mid-slope of the mountain from 443m to 498m altitude. They were located lower part of valley and provided enough humid condition. They had proper light and humidity conditions as they faced south south west, south south east, and south. They were also located at the places deciduous woody plants were distributed for proper light conditions for spring blooming. Iris flowered to use light at the period before the trees thickly covered with foliage. However this unfavorable light condition caused low percentage as 7.04% of blooming individuals in this study. In herbaceous, Vioia chaerophylloides(Regel) W. Hocker, Carex siderosticta Hance, Erythronium japonicum Decne., Oxalis obtriangulata Max., Hepatica asiatica Nakai, Lilium tsingtauense Gilg et cetera were appeared well. We propose that proper pruning of upper branches of the deciduous trees is needed for suitable light condition of management of native sites.

  • Halenia coreana is an endangered, endemic species that is distributed in only a few locations in Korea, such as Mts. Hwaaksan and Daeamsan. It has been recently segregated from H. corniculata, broadly distributed in cold temperate regions that include northern Japan, the Russian Far East, northeastern China, Mongolia, and eastern Europe, where population sizes are usually large. To examine the genetic diversity of H. coreana and evaluate the level of genetic differentiation of the species compared with that of H. corniculata, we surveyed 183 candidate simple sequence repeats (SSR) motif markers for H. coreana and H. corniculata from sequence data of amplified fragments of a specific length in the genome. A total of 17 genomic-SSR markers were selected to examine the levels of genetic diversity and differentiation using 17 samples of H. coreana and 60 samples of three populations of H. corniculata. The results here suggest that the genetic diversity of H. coreana is very low with a high frequency of inbreeding within its population. We found that H. coreana is genetically differentiated from H. corniculata, supporting the recognition of the geographically isolated H. coreana as a distinct species.
