Most of Cudriania tricuspidata Bureau saplings in Korea have been produced by crown division. But the production of Cudriania tricuspidata B. saplings by this method is very low in efficiency and in uniformity. Therefore, to develop Cudriania tricuspidata B. saplings production system by cutting method which is suitable for mass production, several conditions on rooting and growth of cuttings were investigated. The rooting ability of cuttings varied according to temperature on the bed, length, thickness of the hard wood cutting and rooting agent application. Of different concentration of rooting agent, the 5,000 ppm of 1-naphthalenacetic acid(NAA) and Indole butyric acid(IBA) were found to be the highest in rooting of hardwood cuttings; other concentration were in order as follows; 2,500, 1,000 and 10,000 ppm in concentration of rooting agents. The shading ratio of polyethylene film showed the highest rooting ratio of the softwood cuttings at 55%.
