Construction of an identification system in considering molecular phylogeny and phytochemistry

为了给胡椒属植物资源的开发利用提供依据，尝试建立一个易于使用的胡椒属植物鉴定系统。形态学数据库已准备好，但由于材料培养条件不满意，尚未完成。几种化学物质，包括secolignan，是潜在的工具，用于确定分类群被确认。构建了包含29个已知序列的69个OTU的分子系统树。正在整合所获得的信息。

For the bases of development of plant resources in the genus Peperomia (Piperaceae), an easy-to-use identification system was tried to construct. Morphological database was prepared but still not completed due to unsatisfied condition of the material cultivated. Several chemicals including secolignan that are potential tool for the identification of taxa were recognized. And a molecular phylogenetic tree with 69 OTUs including 29 known sequences was constructed. Integration of the obtained information is on the way.
