Abstract
Characteristics of leaf morphology and vegetation were examined in 6 populations of rare endemic tree species, Koelreuteria paniculata Laxm. Additionally we studied genetic variation employing isozyme marker. Nested anova showed that there were statistically significant differences among populations as well as among individuals within populations in all 8 leaf morphological traits. In 7 of 8 traits, variance components among populations were larger than those among individuals within populations. Only a few tree species were found within each population and all the populations seemed to have been disturbed by man. Level of genetic diversity for this rare endemic species was very low, especially compared with those of geographically widespread tree species(A/L=1.1, P=9.5%,
희귀수종인 모감주나무(Koelreuteria paniculata Laxm.) 6개 자생 집단에 대해서 잎의 형태적 특성 및 식생개황을 조사하였으며, 동위효소 분석에 의한 유전변이를 조사하였다. Nested design에 의한 분산분석 결과 8가지 잎의 형태적 특성 모두에서 집단간 및 집단내 개체간에 고도의 통계적 유의성이 인정되었으며, 대부분 형질의 경우 총 분산 가운데 집단간 차지하는 비율이 집단내 개체가 차지하는 비율보다 큰 것으로 나타났다. 식생분석 결과 각 집단별로 출현한 수종 수는 많지 않았으며, 대부분 집단이 인위적 교란을 받고 있는 것으로 나타났다. 다른 수종, 특히 지리적으로 광범위하게 분포하는 수종들과 비교할 때 유전변이는 매우 적고(A/L= 1.1, P=9.5%,
