Abstract: The cutting test with 2-year-old branches of 6-year-old Sabina przewalskii from Zhangye as cutting slips was made. The cutting slips were soaked with growth regulators ZTP, ABT1 and ABT2 rooting powder, and the survival rate and growth condition were investigated after the seedlings stopped growing. The results of variance analysis and multiple comparison showed that there was significant difference among various factors. To soak for 2 h with ABT1 rooting powder with the mass fraction of 100 mg/kg had the greatest influences on the cutting and rooting. To soak for 2 h with ABT1 rooting powder with the mass fraction of 100 mg/kg had greatest influences on the root length and biomass of the cutting taproot. The results of range analysis showed that the most influencing factor on the rooting rate of cutting slips was the kind of growth regulators, the mass fraction was the second, and the soaking time was the third. And the most influencing factor on the root amount and root length of cutting slips was the kind of growth regulators, the soaking time was the second and the mass fraction was the third.
