摘　　要：为了提高5种苦苣苔科植物的扦插繁殖效率,采用叶片扦插试验,研究了浓度分别为100、300、500mg·L-1的IBA对5种苦苣苔科植物生根特性的影响。结果表明:5种苦苣苔科植物的生根特性有所不同,低浓度的IBA对其根和不定芽的发生及提前生根具有促进作用;浓度为100 mg·L-1的IBA适用于尖萼唇柱苣苔、硬叶唇柱苣苔和粉绿异裂苣苔的扦插繁殖;浓度为300 mg·L-1的IBA适用于微斑唇柱苣苔和红苞半蒴苣苔的扦插繁殖。In order to improve efficiency of cutting propagation of five plants in Gesneriaceae, effects of different concentrations of IBA （100, 300, 500 mg＇L-~） on rooting characteristics of five plants in Gesneriaceae were studied by a leaf cutting trial. The results show that rooting characteristics of the five plants are different, and lower concentrations of IBA can stimulate root and adventitious bud formation and can advance rooting. 100 mg＇L-~ IBA is suitable to be applied to cuttings propagation of Chirita pungentisepala, C. sclerophylla, Pseudochirita guangxiensis, and 300 mg＇L IBA is suitable to be applied to cuttings propagation of C. minutimaculata and Hemiboea rubribracteata
