| 摘 要： | 以马铃薯晚熟品种青薯3号脱毒试管苗为材料，研究了试管苗植株不同部位外植体的快繁效应，结果表明：连续培养3代试管苗株高、叶茎色、叶宽、单株叶片数、单株有效茎节数、单株根数、平均根长、植株鲜重和干重等生长参数均以植株中部外植体最高，基部外植体优于顶部；中部外植体的单株有效茎节数比基部和顶部分别多4．6和2．6个。

| Abstract: | Virus-free plantlets of potato cultivars:Qingshu No.3 was used to studied in vitro micropropagation in relation to nodal position of potato explants.The results showed that plant height,color of stems and leave,leave width,number of effective stem cutting per shoot,leaf number per shoot,and fresh and dry weight of plantlets were produced from nodal explants from middle portion of shoots(NEMPS) more than those of upper portion and basal portion. |
