摘要： 为了研究外源激素及切割方式对东方百合‘索邦’鳞片扦插繁殖的影响，本试验以东方百合‘索邦’鳞片为试验材料，按不同浓度外源激素IBA、B12和纵切方式处理进行扦插试验。结果表明：200 mg/L的外源激素IBA处理，小鳞茎发生率、繁殖系数、直径、根数、根长都显著高于100、300 mg/L浓度处理；200 mg/L IBA + 5 mL B12处理，小鳞茎发生率、繁殖系数、直径均显著高于未给予B12处理的鳞片，但生根数与根长显著低于200 mg/L的IBA处理；对鳞片进行纵切，切割处理后的鳞片小鳞茎发生率、繁殖系数、直径、根数、根长都显著高于未切割的鳞片。因此，一定浓度的外源IBA、B12及纵切处理能促进小鳞茎的发生，提高繁殖系数，增加根数、根长。

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.
