摘要
基于形态学特征,目前山茶属植物分类主要有Sealy、张宏达和闵天禄所创立的3种系统.由于所关注的表型特征不同,这3种分类观点存在较大争议.本文从国内外山茶属分类研究历史出发,对山茶属分类和系统发育研究进展进行综述,主要对基于不同的标记类型对山茶属植物系统发育重建的相关研究进行整理总结,评价不同标记在山茶属物种系统发育分析中的利弊.提出目前分类中的问题和今后的重点研究方向,以期为重建山茶属物种间系统关系和解决分类争议提供一定的参考.
Abstract
The genus Camellia comprises a vast number of species that are widely distributed across various regions.The frequent inter-specific hybridization results in,controversial and unstable taxonomy and systematics among different species,which also poses a greater challenge for infrageneric classification within Camellia.Based on morphological features,Sealy,Chang Hongda,and Min Tianlu have established three classification systems for species in the genus.However they hold different opinions on the taxonomic significance of each character.This paper presents a comprehensive overview of the classification and phylogenetic research progress on the Camellia genus from a global perspectives.Pertinent research on phylogeny reconstruction of Camellia genus based on various marker types were summarized,appraise the merits and demerits of these markers in elucidating phylogenetic relationships,and propose future research directions to address current classification issues.The paper provides valuable insights into reconstructing the systematic relationship within the Camellia genus and resolving classification disputes.
