摘要
利用SRAP分子标记对34种铁兰属植物的亲缘关系进行分析。挑选了10对特异性引物，共扩增出402个位点，多态性位点376个，多态性百分率94％，相似系数0．1343—0．9556。聚类分析发现，34份铁兰属植物材料在相似系数为0．78时可划分为4个类群。分布地域是影响聚类结果的重要影响因子，实验证明Tillandsiajuncea与rsubgen．Anoplophytum亚属有较近的亲缘关系。
In this paper, SRAP was used to assess the genetic relationship of 34 Tillandsia varieties. Ten pairs of prim- ers were selected. 402 bands were amplified, of which 376 bands （94%）were polymorphic, and the Nei＇s genetic simi- larity coefficients ranged from 0. 134 3 -0. 955 6. According to the UPGMA method,we made the cluster analysis by u- sing the NTSYS software,3g Tillandsia plants could be divided into four groups at the similarity coefficient of 0.78. The geographical distribution was a principal factor for the cluster result. The experiment indicated that TiUandsia juncea and T. subgen. Anoplophytum had close relationship.
