개병풍(Astilboides tabularis (Hemsl.) Engl.)의 보전 및 복원을 위한 기초자료를 확보하기 위해 자생지 환경특성을 조사하였다. 자생지 고도는 해발 432-1,413 m까지 다양하게 위치하 였으며, 경사도는 16-49.5°로 비교적 급한 경사지에 자라는 것 으로 확인되었고, 주로 북사면을 선호하는 것으로 나타났다. 개 병풍 자생지의 식생분석 결과 12개 방형구에서 조사된 관속식 물은 246분류군이었으며, 개병풍이 주로 분포한 초본층의 중요 치는 개병풍이 20.40%로 가장 높았고, 다음으로는 관중(4.56%), 도깨비부채(3.72%), 노루오줌(2.81%), 대사초(2.67%), 단풍취 (2.65%), 벌깨덩굴(2.46%)의 순으로 나타나 이러한 종류들이 개병풍과 유사한 환경을 선호하는 것으로 판단된다. 종다양도는 평균 1.23, 우점도와 균등도는 각각 0.11과 0.86으로 산출되었다. 토양분석 결과 낙엽층의 두께는 2-10 ㎝이었으며, 토심 은 20.8-67.5 ㎝로 나타났다. 토성은 사질토, 미사질토, 양토 등이었으며, pH는 5.63-7.74, 유기물함량은 8.88-42.55%, 그 리고 질소함량은 1.40-6.58 ㎎/g으로 나타났다.
This study was conducted to investigate the environmental characteristics of natural habitats, and the genetic variations in samples from 19 different quadrates of Asplenium scolopendrium 10 habitats. The natural habitats of A. scolopendrium were located at an altitudes 110-973 m with inclinations of 7-30˚. All the quadrates were located on north facing slopes. The average field capacity of the soil is 31.4%, with organic matter at 16.7%, and the pH is 5.84. The soil texture was confirmed as sandy loam in 8 habitats and silt loam in 2 habitats. A total of 214 vascular plants were identified from 10 habitats. The importance value of the herbaceous layer (H) was the highest in A. scolopendrium, at 10.4%, followed by Arachniodes standishii (7.3%), Dryopteris crassirhizoma (6.5%), and Polystichum tripteron (5.3%), which implies that the natural habitats of A. scolopendrium are affinity with ferns. The species diversity of A. scolopendrium was estimated as on average 1.09, while the dominance and evenness were 0.12 and 0.87, respectively. The result of the RAPD analysis, among 59 bands amplified with a primer, 25 (42.4%) showed polymorphism. Twenty-one individuals of 10 habitats could be classified into four groups with similarity coefficient values ranging from 0.74 to 1.0. Mt. Mullae and Geumdaebong populations shows basal branching within the 21 individuals. Ulleung-do island and Jeju-do island population forms an independent clade, respectively. Mt. Moak and Byeonsan-bando clade formed a sister to the Ulleung-do island and Jeju-do island clade.
This study intended to investigate environmental factors including soil and vegetation in order to understand the environmental and ecological characteristics of 12 different habitats of Iris odaesanensis. These habitats, according to investigations, are mostly located at elevation of 280 m to 1,555 m with angles of inclination ranging from 2 degree to 30 degrees. A total of 273 vascular plants are identified in 23 quadrates of 12 habitats. Dominant species of woody plants in 12 habitats are represented as Quercus mongolica in the tree layer (T1) and the subtree (T2) layer, and Lespedeza maximowiczii, Lindera obtusiloba, Rhododendron schlippenbachii in the shrub (S) layer. The importance value of Iris odaesanensis is 9.65%, as regards the herbaceous layer, and 6 highly ranked species such as Carex siderosticta (3.92%), Meehania urticifolia (2.67%), Spodiopogon cotulifer (2.58%), Aconitum pseudolaeve (2.51%), Carex bostrychostigma (2.28%) and Disporum smilacinum (2.09%) are considered to be an affinity with Iris odaesanensis in their habitats. The degree of their average species diversity is 1.32, and that of dominance and evenness are 0.08 and 0.89, respectively. The type of soil is sandy loam and loam, and the average field capacity of soil is 28.31%. Their average organic matter is 16.71%, soil pH 5.29, and available phosphorus is 9.29%. Correlation coefficients analysis based on environmental factors, vegetation and soil analysis shows that the coverage of Iris odaesanensis is correlated with pH and dominance, and species richness is positive related with species diversity.
This study were focused on the genetic relationship using RAPDs and some morphological characteristics among eleven taxa Aster collected in Korea. Twenty random primers were selected, a total 216 DNA bands were generated and 213 bands were shown polymorphism among species. The collected eleven taxa were clustered into five groups at 0.609 similarity index. The first group was A. glehni, A. ageratoides, A. maackii and A. scaber was clustered at 0.713 of genetic distance. The second group was A. tataricus and A. koraiensis and the third group was A. spathulifolius, the forth group was A. yomena, A. hayatae and A. hispidus and the fifth was A. tripolium.
