摘　　要：用频率分别为 2 7KHz和 40KHz的功率超声对地灵组培苗进行不同时间的处理 ,继代培养后进行观察。结果显示 :经超声处理的叶片形成愈伤组织时间比对照组提前 ,但在愈伤组织生长后期增殖与对照组没有差异 ;超声处理后的腋芽生长状况比对照组好 ,表现为腋芽高度增加 ,直径加粗 ,说明超声在一定程度上可以促进植物的生长。Using the power ultrasound 27 KHz and 40 KHz respectively to treat with Stachys sieboldii in different treatment time then the treated materials were sub cultured. We observed that the leaves callus formation time of ultrasound treatment groups was shortened comparing with the control ones. However, there was no apparent difference during the later growing period. The axillary buds of ultrasound treatment groups grow better than the control ones, such as increased height and thickened stem. It shows that power ultrasound, to some degree, could stimulate the growth of plant.
