摘　　要：Five different parts of Rosa damascene Mill. twigs were treated with hormone solution （50 mg/L NAA＋100 mg/L IBA） and planted in base material. After 50 d of growth, the survival rate and rooting condition were investigated. The results showed that the survival rate from 5 different parts of cutting stem decreased from top to bottom （upper 98.22%, middle and upper 95.12%, middle 91.10%, middle and lower 72.90%, lower 71.12%）. The same results were also observed in the number, total length and fresh weight of secondary roots of cutting segments from different parts of twigs.Five different parts of Rosa damascene Mill. twigs were treated with hormone solution （50 mg/L NAA＋100 mg/L IBA） and planted in base material.
