This study was conducted to develop mass production method of Potentilla fruticosa L. for a commercial use. Effects of proper cutting time, and type and concentrations of plant growth regulators on the rooting were examined. When Potentilla fruticosa L. was cut on April 16th, average number of roots was 4.2, the number of shoots was 5.3 and the root production rate was 85%. By soaking in 1,000 mgㆍL-¹ of IBA solution for 1 hour, the number of roots was 36.8, fresh weight was 780 mg per cutting, and rooting rate was 95%.
