황해쑥(Artemisia argyi H.Lév. & Vaniot)의 작물 특성과 플라보노이드 함량

This study was conducted to determine the crop characteristics such as morphological characteristics, seed germination, planting density, harvest time and flavonoid contents in the medicinal plant mugwort (Artemisia argyi) in order to develop this plant as a valuable new cash crop. We investigated the morphological parameters of A. argyi in early August, including whole plant, leaf, trichome, root, inflorescence and capitulum morphology. Achene-type seeds without hairs formed in early August. The seeds germinated at the highest rate (52.7%) at 15°C compared to other temperatures. Stem diameter, leaf dry weight, root length and root diameter were higher under a low planting density (30 × 30 cm) compared to other treatments in September. However, the harvested aerial parts had higher yields (1,318 and 1,253kg/10a DW) from plants grown at planting densities of 30 × 10 cm and 30 × 20 cm compared to 30 × 30 cm (1,097 kg/10a DW). The yields of aerial parts significantly increased until August. Apigenin, eupatilin and jaceosidin concentrations were higher in mugwort harvested in September vs. August. Apigenin was detected in underground part(rhizome and root) whereas eupatilin and jaceosidin were only detected in stems and leaves. These results should be valuable for designing cultivation and harvesting methods for A. argyi. KCI Citation Count: 0
