Abstract

The aim of this study was to examine geographic variation to support a genetic resource conservation plan of rare endemic Picea jezoensis (Siebold & Zucc.) Carriere. Three populations of P. jezoensis were analysed using multivariate analysis for 7 characteristics of needle morphology. In the morphological characters, seven characters of needle were 15.11 mm (needle length), 1.43 mm (needle width), 0.42 mm (needle thickness), 10.9 (length / width of needle), 3.6 (width / thickness of needle), 0.47 mm (Distance between resin duct and vascular), 17.4 ea. (number of stomata row), respectively. Nested analysis showed that were statistically significant differences among populations as well as among individuals within populations in 6 quantitative characters. In 5 of 7 characters, variance components among populations were higher than those among individuals within populations. Cluster analysis using complete linkage method showed two groups (Mt. Gyebang populations was genetically distinct from the other two populations) to Euclidean distance 0.4. Among principal components, primary 2 principal components appeared to be major variables because of the loading contribution of 100%.

가문비나무의 유전자원 보존 전략 수립을 위해 3개 집단의 지리적 위치에 따른 침엽의 7가지 형태적 특성에 대한 변이를 조사하고 다변량분석을 실시하였다. 침엽의 평균생장은 침엽길이 15.11 mm, 침엽폭 1.43 mm, 침엽두께 0.42mm, 침엽길이/폭 10.9, 침엽폭/두께 3.6, 유관속과 수지구와의 거리 0.47, 기공열수 17.4개로 나타났다. Nested 분산분석 결과 유관속과 수지구와의 거리 특성을 제외한 6가지 양적특성들에서 집단간 및 집단 내 개체 간에 유의적인 차이를 보였으며, 대부분의 형질들은 총 분산 가운데 집단 내 개체 간 보다는 집단간 차지하는 비율이 큰 것으로 나타났다. 7가지 양적특성들에 대한 집단간 유연관계는 거리지수 0.4에서 계방산집단이 지리산과 덕유산집단과는 별개의 상이한 그룹을 형성하였으며, 유집군의 유형은 제2주성분까지가 전체 변이의 100%를 설명하였다.
