다변량 분석에 의한 둥굴레속 식물의 분류

Abstract

This study was conducted to obtain the basic data for practical use of the Ploygonatum genetic resources. The 20 collections were analyzed by principal component analysis of 8 characters and cluster analysis. In the principal analysis, the first, the second and the third components contributed 54. 10%, 18.95% and 11.62% of the variations, respectively. The cumulative contribution from the first, to the third principal components was 84.67%. The first principal component was related to shape and size of plant, and assimilatory, reserve and reproductive organs. The second principal component was related to growth and development of plant, and reserve organ. And the third principal component was related to Growth and development of plant. Based on cluster analysis, the 20 collections were classified into 4 distinct groups with the average distance greater than 0.7 between groups. Group Ⅰ was Polygonatum sibiricum DELAT and Group Ⅱ included P. odoratum var. pouriflorum OHWI , P. odoratum var. pluriflorum Ohwi for 'Variegatum' Y. Lee, for. nov., P. odoratum var. thunberfii HARA and P. odoratum var. maximowiczii KOIDZ Group Ⅲ was P. involucratum MAXIM P. desoulavyi KOMAROV and P. humile FISHER ex. MAXIM And Group Ⅳ included P. lasianthum var. coreanum NAKAI and P. inflatum KOMAROV
