Study on the Cutting Propagation Technology of Wild Rosa
R. xanthina var. Normalis, R. sertata×rugosa and R. davurica Pall.were used to research the effects of different concentrations ( 50, 100, 150 mg/L ) of IBA and processing times (0, 30, 60, 90 min) on cutting rooting under the greenhouse.The results showed that:(1) The best treatment of cutting rooting of R. xanthina var. normalis and R. davurica Pall.was 100 μg/mL for the concentration of IBA and the time for 60 min;(2) The suitabletreatment of cutting rooting of R. sertata×rugosa was 150 μg/mL for the concentration of IBA and the time for 60 min.
