Abstract: The effects of exogenous hormones and rip cutting of scale were studied with Lilium Oriental Hybrids‘Sorbonne’. In this study, the scale of Lilium Oriental Hybrids‘Sorbonne’was taken as experimental material and respectively treated with different concentration of exogenous hormone IBA, B₁₂ and rip cutting of scale. The result showed that the concentration of 200 mg/L exogenous IBA had the highest scale propagation coefficient, bulblet incidence, diameter, root length and produced the most roots number than concentration of 100 and 300 mg/L treatment. The concentration of 200 mg/L exogenous IBA and 5 mL B₁₂ had higher scale propagation coefficient, bulblet incidence, diameter than the treatment without B₁₂, but the number of root and the length of root were significantly lower than that under the treatment of concentration 200 mg/L IBA. In terms of rip cutting of scale, the scales that were cut had the highest scale propagation coefficient, bulblet incidence, diameter, root length and produced the most roots number than the scales which were not cut. So a certain concentration of exogenous IBA, B₁₂ plus cutting processing could promote the occurrence of small bulbs, improve scale propagation coefficient, increase the number of root and the length of root.
