Abstract:

The taxonomic disorder in genus of Arundinaria Michaux is the disputing focus in the taxonomic study of leptomorph bamboos.For a long time,there is no suitable strategy to study the genus of Arundinaria and the related genera.In this paper we presented a method of using the SSR primers of rice to settle the problem according to the near phylogenic relationship between bamboo and rice.Differing to the traditional taxonomy,it showed that there was a large differentiation beween genus of Bashania Keng f.et Yi and related genera of Arundinaria Michaux,and proved that Bashania Keng f.was regarded as a distinct and isolated genus.The taxonomic problem of Arundinaria amabilis (McClure) Keng f. was also discussed in this paper.It provided a new result for the relationship of the genus of bamboo related to Arundinaria Michaux from different aspects comparing to the traditional study.It also offered a reference for the phylogenic study of Arundinaria Michaux in a broad sense by modern molecular biotechnique.This study put forth new thought and strategy to carry out molecular biology research in bamboo.
