应用DELTA系统对几种球束梗孢Gibellula spp.的分类研究

Classification of Gibellula spp. by DELTA system

摘要:

【目的】通过DELTA数据库及其功能扩展，对所采集的球束梗孢标本进行分类鉴定。【方法】利用基于30个表型特征建立的DELTA数据库，通过生成的检索表，自然语言描述，分类单位聚类树及交互式自动鉴定系统进行鉴定。【结果】全部标本鉴定分属为3个种，它们是尾生球束梗孢(粗壮球束梗孢) Gibellula clavulifera var. clavulifera (Petch) Samson & H.C. Evans，密球束梗孢G. leiopus (Vuill. ex Maubl.) Mains和丽球束梗孢G. pulchra Cavara。【结论】 基于DELTA系统所建立的的球束梗孢属表型特征数据库及其功能扩展，为该属后续的分类研究和系统发育重建提供了一个有价值的信息平台。

Abstract:

[Objective] To identify some specimens of Gibellula spp. collected in China, the DELTA expert system and its function extension were performed. [Methods] The DELTA expert system was built based on 30 characters of the genus Gibellula, and then, the key, natural descriptions, distance matrix, phenetic tree and interactive automatic identification were performed. [Results] All the specimens were identified as three species as follows, respectively: Gibellula clavulifera var. clavulifera, G. leiopus and G. pulchra. [Conclusion] Based on the DELTA expert system, a database of phenotype characters and its function extension could provide a valuable information platform for the taxonomic and phylogenetic study of the genus Gibellula in the future.
