Abstract:: Taking Sansevieria trifasciata Prain.var.laurentii N.E.Brown，Rosa hybrida and Pelargonium hortorum Bailey as test materials，the effects of different auxin regulators and their concentrations on rooting of cuttings of three kinds of garden plants were studied.The results showed that 100 mg/L IBA was better for leaf base cuttings of Sansevieria trifasciata Prain.var.laurentii N.E.Brown and 100~200 mg/L IBA or 200 mg/L NAA was better for leaf top cuttings.Their rooting rates reached 100%.100~200 mg/L IBA and 100 mg/L NAA were better for rooting of stem cuttings of Rosa hybrida and the rooting rates reached 75.6%~77.8%.The rooting rates of all stem cutting treatments of Pelargonium hortorum Bailey reached 100%，but 100 mg/L NAA or 50 mg/L IBA was the best for rooting of cuttings from the comparison of the average number of roots，and 25~300 mg/L IAA inhibited the number of roots.
