다변량 분석에 의한 국내산 대추나무 품종의 형태적 특성과 유연관계

Abstract

- The objectives of this study, an analysis of fruit and leaf morphological characteristics among the fiveZizyphuscultivars could be used for the investigation of cultivars classification and could provide information to make outthe UPOV TG(Test Guidelines). ANOVA tests showed that there were statistically significant differences in all fruit andleaf morphological characteristics among the five Zizyphuscultivars at 1% level. But, for kernel characteristics,differences were statistically non-significant among the cultivars. Approximately, the Wolchul and Boeun cultivarsshowed larger and smaller values in overall characteristics and cultivars, respectively. The results of principal componentanalysis(PCA) for the fruit and leaf morphological characteristics showed that the first for principal components(PCs)explained about 65.3% of the total variation. The first PC was correlated with those characteristics that were mainlyrelated to the terminal leaf length(TLL), leaf length(LL), fruit length(FL), terminal leaf width(TLW), and leaf petiolelength(LPL). The second and third PC was mainly correlated with the terminal leaf morphological index(TLMI).Therefore, these characteristics were important to analysis of the fruit and leaf morphological characteristics andclassification among the five Zizyphuscultivars. Cluster analysis using UPGMA method based on principal componentsshowed that five Zizyphuscultivars could be clustered into two groups. Group comprises Mudung, Wolchul, and Bokjoand Geumsung cultivars, Group is Boeun cultivar. These results well similar to that of principal component analysis.Key words -Zizyphus, Morphological characteristics, Classification, Multivariative analysis- 106 -- 107 -
