Abstract: This paper is of propagation of etiolated softwood cuttings from five cultivars of dwarf Chinese tree peony, ‘Yinfen Jinlin’, ‘Lantianyu’, ‘Jinyu Jiaozhang’, ‘Xiaohuhong’, and ‘Shiyuanbai’, respectively. As the results, rooting rates of five cultivars mentioned above are 91.0% , 80.9% , 78.6% ,40.6% , 20.0% , respectively. The etiolated softwood cuttings with 4 - 6 cm length and 0.5 cm thicker in diameterwere taken in the middle of October, emerged their bases in the rooting promoter solution, IBA 100 mg/L or‘ABT 2’150 mg/L for 16 h at 20 - 25 ℃, inserted into the cutting bed of vermiculate with particle of 3 - 4 mm in diameter. The highest rooting rate of 93% was achieved for the cultivar‘Yinfen Jinlin’. Adventitious roots occurred were strong and young plants grew well after transp lanted them into pots.
