Abstract
This study was conducted to examine variations of 35 morphological characteristics of 6 natural populations of Zelkova serrata in Korea. On the basis of the results of the ANOVA tests, the populations were significantly different in 16 of the 20 quantitative morphological characteristics that were tested. In particular, the 'Cheongju-si Gutdae Mountain' population showed larger values in 9 of the 20 quantitative characteristics that were examined. In the results of principal component analysis of the characteristics, examined characteristics were not suitable for the variation of 6 natural populations. According to the results of cluster analysis, 'Namhae-gun Mijori Evergreen Forest' population was grouped with 'Yangpyeon-gun Yongmun Mountain' population to the nearest group, and then 'Cheongju-si Gutdae Mountain' population, 'Boeun-gun Sokri Mountain' population, 'Daegu metropolitan city Palgong Mountain' population, and 'Hamyang-gun Sang Forest' population were grouped in regular sequence.
