摘　　要：以"拼图""红卷毛"和"花毯"3个矾根品种为材料,研究了不同浓度生根粉处理对3个矾根品种扦插生根的影响。结果表明:矾根属于愈伤组织生根型品种,一般扦插30 d左右开始生根;"拼图"品种适宜用1 000~3 000 mg/L的生根粉短时(5~30 s)处理,"红卷毛"品种适宜于500~1 000 mg/L的生根粉浸泡(10 min左右)处理,而"花毯"品种的生根处理方法有待进一步研究。This study was conducted to test how the Heuchera micrantha cutting propagation would be affected with the ABT at differentconcentrations and different processing time treating three varieties of Heuchera micrantha,namely,Pintu,Hongjuanmao and Huatan.Theresults showed that the rational use of ABT could effectively improve the rooting rate of Heuchera micrantha cutting,with callus rootingabout30d after cuttage planting.The Pintu roots well in the treatment of the ABT concentration of3000~3000mg/L and the ABT dippingtime for5~30s.The Hongjuanmao roots well at the concentration of500~1000mg/L and through the dipping for10min.And the Huatanneeds further research in the rooting treatment.
