Abstract

Morphological and geographical examinations as well as phylogenetic analyses using ITS sequences were performed for Asparagus L. in Korea. A total of five species of Asparagus were confirmed to be distributed in South Korea. The shape of cladophylls, length of pedicels, and shape of perianth were considered to be important characteristics for the identification of Koran Asparagus species. A monophyly of each species was evident in the ITS phylogenetic trees in which multiple accessions (5 to 24, depending on species) represented each of the five Korean species. A. rigidulus Nakai, once considered conspecific to A. schoberioides Kunth, formed a distinct lineage in the ITS trees. Pedicels of A. rigidulus, which is distributed mainly in coastal areas, were about two times longer than those of A. schoberioides occurring in inland areas, suggesting that they should be treated as distinct taxa.

한국산 Asparagus L. (비짜루속)을 대상으로 외부형태 형질을 재검토하고 ITS 염기서열을 사용한 계통분석을 실시하였다. 외부형태를 분석한 결과 엽상경의 형태, 소화경의 길이, 화피의 형태 등이 종을 식별하는 데 중요한 형질이었으며, 남한에는 최근에 분포가 확인된 A. davuricus Fisch. and Link (망적천문동)을 포함하여 총 다섯 종의 Asparagus가 자생하는 것으로 확인되었다. 각 분류군별로 5 내지 24 개체를 포함하여 수행한 ITS 염기서열 계통분석에서 각 분류군은 모두 단계통군을 이루었다. 특히 A. schoberioides Kunth (비짜루)의 이명으로 처리되고 있는 A. rigidulus Nakai (노간주비짜루)는 A. shoberioides와 8개의 뉴클레오티드 자리에서 차이를 보이면서 독자적인 단계통군을 형성하였다. 독도, 제주도 및 중남부 해안에 주로 자라는 A. rigidulus의 소화경은 내륙에 분포하는 A. schoberioides에 비해 약 2배 길었다. 두 종의 형태적, 지리적, 계통 유전학적 차이는 A. rigidulus를 A. schoberioides와 다른 독립된 종으로 인정해야 함을 말해준다.
