Abstract

To clarify the morphological and geographical differentiation among the polyploid complexes of L. lancifolium collections in Korea, the mo게hological variation of 173 accessions were analyzed by ANOVA (one-way analysis of variance) and PCA (principal component analysis) on the basis of 38 morphological characters. 173m accessions were grouped into 78 diploids and 95 triploids by ploid levels and the triploids separated into 75 inland triploids (all around the Korea) and 20 island triploids (Backryung-do and Sochung-do, westemmost and northernmost islands of Korea) by geographic distribution and morphology. Island triploids showed significant morphological differences with inland triploids in ANOVA by many floral and leaf characters. In PCAs, diploids were separated from inland triploids by having longer plant height, smaller flower characters, higher pollen fertility and more stomata. The first four principal components accounted for 44.1% of the total variation. Plots of the island and inland groups for the first and second principal components separated each other with slight overlapping. Although the ploid forms are different between diploid and island triploid, island triploids were more closely overlapped with diploids by principal component 1 and 2 than inland triploids. This reflects that the whole external morphology of island triploids are similar to that of diploids. This, the phenotypic differentiation between inland and island triploids seems to be partly related to their geographical origins.

참나리 2, 3배체 복합 배수성 집단에서 형태적, 지리적 분화를 명확히 하기 위해서 173개 군락에서 수집된 참나리의 38개 형질에 대한 분산분석(ANOVA)과 주성분분석(PCA)을 수행하였다. 그 결과, 173개 참나리 개재들은 배수성에 의해 78개의 2배체와 95 개체의 3배체로 구분되었고, 3배체는 지리적 분포와 형태적 특성에 의해 73개의 내륙 3배체(남한 전지역)와 20개의 섬지역 3배체(백령도와 소청도)로 구분되었다. ANOVA분석에서 섬지역 3배체는 잎과 꽃의 여러 형질들에 의해 내륙의 3배체와 뚜렷한 형태적 차이를 나타내었다. 주성분 분석에 의한 누적기여율은 4차 주성분까지 44.1%를 나타내었고, 주성분분석에서 2배체는 긴 초장, 작은 꽃의 형질들, 높은 화분임성, 더 많은 기공 수 등의 형질에 의해 내륙의 3배체와 구분되었다. 섬지역 3배체도 약간의 중복은 있었으나 1, 2차 주성분에 대한 2차원 분포도에서 서로 구분되었다. 한편, 배수성이 다를지라도 섬지역 3배체와 2배체는 주성분 1과 2의 요인에 의해 완전한 중복을 나타내었다. 이러한 사실은 섬지역 3배체와 2배체가 외형적으로 유사하다는 것을 반영한다. 이와 같이 섬지역과 내륙의 3배체의 형태적 차이는 지리적 기원을 반영하는 것으로 생각된다.
