在进行竹类种质资源研究,承建世界竹藤标本馆(国际代码:ICBR)等项目的过程中,根据实地调查、野外采集、文献调研与专家随访等形式,基于与世界体系接轨的中国植物志英文及修订版Flora ofChina第22卷34属体系,以及巴山木竹属Bashania ***&***替代青篱竹属ArundinariaMichaux等后续研究成果的基础上,初步整理报道处于我国亚热带季风性湿润气候区的重庆市,其下辖23个市辖区、11个县、4个自治县,共82402.95km2的土地上,有竹类植物16属72种(表1),珍稀、特有种质比较丰富.基于Fo C 22,对易同培等先生编著,分别于2008年出版的《中国竹类图志》、1997年出版的《四川植物志·第12卷》、1997年出版的《四川竹类植物志》等专著及其后续研究文献所涉及到重庆的单竹属、慈竹属、绿竹属、茶秆竹属、筇竹属、月月竹属进行了系统学修正,将倭竹属中名更名为鹅毛竹属。将易书之马甲竹、笔秆竹、菲白竹、无毛翠竹,菲黄竹、铺地竹、翠竹、钓竹、南川镰序竹、坝竹、丰都镰序竹等进行学名更新,以便于国内、外对称应用。随着重庆竹类资源考察与采集深度的增加,可以逐步探明其多样性情况。

[Objective] The aim was to research the relationship and genetic diversity of Indocalamus. [Method] Using 13 samples of Indocalamus and 3 samples of Sasa as materials, the intergenic regions of trnL-trnF gene in chloroplast were amplified by PCR, and sequence analysis and phylogenetic trees construction were carried out. [Result] Using the universal primer, the intergenic regions of trnL-trnF were amplified, the lengths of the segments varied from 1 008 bp to 1 103 bp, of which 940 bp was compared. The dendrogram of trnL-trnF sequences showed that Indocalamus and Sasa were clustered together and they were homologous by 99%. All the samples were divided into five groups, the first group included 12 samples such as Indosalamus pedalis, I. pumilus, I. victorialis, I. longiauritus, I. tessellatus, Sasa sinica, Sasa pygmaea, I. barbatus, I. guangdongensis, I. herklotsii, I. Hirtivaginatus and S. fortunei. I. decorus, I. lacunosus, I. Latifolius and *** were respectively divided into four groups. [Conclusion] The high homology of all samples showed the low evolution speed and little information sites which suggested that the phylogeny of Indocalamus could not be well resolved by the intergenic region of trnL-trnF.
