한국산 갈매나무과(Rhamnaceae)의 열매와 종자의 형태에 의한 분류학적 연구 = A Taxonomic Study of the Korean Rhamnaceae Based on Fruit and seed Morphology

다국어 초록 (Multilingual Abstract)

This study was conducted to compare and analyze the fruit and seed morphology of Korean Rhamnaceae species in order to identify taxonomically informative characters. A total of 16 species belonging to seven genera, including 15 native species and one cultivated species, were examined. Fruits and seeds collected at the mature stage were observed using a stereo microscope and X-ray computed tomography(CT).
Distinct differences were identified among the genera in the form of the mesocarp, the morphology of the endocarp, the presence or absence of endocarp grooves, and the number of pyrenes. Rhamnus is characterized by a drupe with a membranous endocarp, where the persistence of the endocarp at maturity and the shape of the aperture at the seed base were confirmed as diagnostic characters for species delimitation. The remaining six genera (Berchemia, Sageretia, Rhamnella, Hovenia, Paliurus, Ziziphus) exhibit a woody endocarp. Paliurus ramosissimus (Lour.) Poir., belonging to the genus Paliurus, was previously classified as a dry fruit in domestic literature, but this study confirmed it to be a three-loculed drupe through X-ray CT analysis.
Based on these findings, we propose the quantitative and qualitative characteristics for Korean Rhamnaceae grounded in fruit and seed structural characteristics. This work represents the first morphological taxonomic study focusing on the fruits and seeds of Korean Rhamnaceae. Furthermore, the application of non-destructive three-dimensional imaging using X-ray CT provided significant insights into fruit and seed cross-sectional structures, providing meaningful implications for resolving generic and species-level relationships and serving as foundational data for future molecular phylogenetic research.
