This study was conducted to examine the effects of media, crown position, clone ,a nd plant growth substances upon the rootability of cuttings for the establishment of the method of mass production by cutting of Dendropanax morbifera Lev. the artifical soil mixtureof vermiculite, perlite and peatmoss (1 : 1 : 1 v/v/v) with IBA 100mg /l treatment was most effective on the rooting rate (85%) was obtained with semihardwood cuttings, which were collected early-August after the first growing seasons. The effect of crown position on rooting of cuttings were obsreved. Average percentage rooting of cuttings on crown position showed 78% , 72% and 65% in middle , upper and lower part with IBA 100mg/l treatment , respectively. Among the four treatment levels of IBA, the highest rooting rate was observed in 100mg/l IBA treatment.
