Abstract:

In order to make clear the taxonomic status of Acer trialum L. in Acer genus, the genetic relationship between Acer trialum L. and Acer buergerianum Miq. was studied based on AFLP (amplified fragment length polymorphism) technique. A tree diagram was constructed using UPGMA method. The results showed that 202 bands were amplified with 8 primer pairs. Among them, 99 bands were polymorphic (49.01%). The result showed that AFLP could be used to analyze genetic relationship between Acer trialum L. and Acer buergerianum Miq.. Cluster analysis showed that Acer trialum L. and Acer buergerianum Miq. were divided into 2 different groups, respectively. According to the results, Acer trialum L. was a new specie of the genus of Acer by AFLP molecular evidence.
