Abstract

Aiming to determine the taxonomic identity of Gang-hwa-yak-ssuk as a cultivated plant, this study analyzes ITS sequences and compares their external morphologies with the genus Artemisia, which have a similar external morphology. Thus far, we have considered A. indica as the original plant of Gang-hwa-yak-ssuk, but Gang-hwa-yak-ssuk is better grouped with A. argyi, not A. indica, for the following reasons: Gang-hwa-yak-ssuk has the same characteristics as A. argyi in terms of the natural habitat, in that it is 1-bipinnately cleft or parted in the external morphology of its leaves, and because the white glandular trichome is distributed on the adaxial surface. This is in addition to the result of ITS sequence analysis. Therefore, we can define Gang-hwa-yak-ssuk as a cultivated plant that originates from A. argyi and not A. indica.

재배식물인 강화약쑥의 분류학적 실체를 파악하기 위하여 외부형태가 유사한 쑥속식물을 대상으로 외부형태 비교와 ITS 염기서열분석을 수행하였다. 지금까지 강화약쑥의 기원식물은 쑥으로 알려져 왔으나, 잎의 외부형태에서 1-2회 우상 중열 또는 심열하고 잎 표면에 백색선모가 분포하는 특징은 황해쑥의 잎과 동일하였으며, ITS분석에서도 강화약쑥은 쑥과 유집되지 않고 황해쑥과 더 가깝게 유집되었다. 따라서 강화약쑥은 쑥이 아닌 황해쑥에서 기원된 재배식물로 판단되었다.
