摘要

利用分子鉴定和形态学分析, 对采自广东湛江的江蓠科物种进行了分类学研究。经鉴定, 共发现4种江蓠科物种, 即细基江蓠Gracilaria tenuistipitata、硬江蓠G.firma、帚状江蓠G.edulis和异枝拟江蓠Gracilariopsis bailinae。文章详细讨论了此4种江蓠的分类学特征和系统发育关系, 在此基础上结合文献数据, 明确了细基江蓠、细基江蓠繁枝变种G.tenuistipitata var. liui与长喙江蓠G.longirostris为同一个种, 以及硬江蓠与张氏江蓠G.changii为同一种。本研究修订了我国南方沿海江蓠科物种的分类信息, 也为湛江海域大型海藻资源的保护和开发提供了分类学依据。

Abstract

According to the molecular and morphological analysis, the species of Gracilariaceae was studied using the samples collected from Zhanjiang, Guangdong province, China. Four Gracilariaceae species were identified, namely: Gracilaria tenuistipitata, G.firma, G.edulis and Gracilariopsis bailinae. Their taxonomic characters and phylogenetic relationships were discussed in detail, and combined with data from the literature, it was clarified that G. tenuistipitata, G. tenuistipitata var. liui and G. longirostris are the same species, and G. firma and G.changii are the same species. This study revised the taxonomic information of Gracilariaceae species in the coastal waters of southern China, and also provided a taxonomic basis for the conservation and development of macroalgae resources in Zhanjiang sea area.

Key words： Zhanjiang; Morphology; Gracilaria; Phylogenetic analysis
