梨属植物分类研究进展

Advances in the research on the taxa of Pyrus plants

梨属植物主要分布在欧亚大陆和北非,一般认为起源于中国西南部山区。通过简要回顾梨属植物的主要分类研究成果,比较不同学派专家对梨属植物分类研究的分歧,分析了梨属植物形态分类困难的形成原因,梨属植物的配子体自交不亲和性导致了植物形态分类研究的差异,结合生化指标的分类研究和结合分子技术的分类研究部分验证了形态分类的结果。并结合最新命名法规"墨尔本法规"和人工智能,对梨属植物分类研究提出了展望,梨属植物的分类对种质资源保护、评价和利用具有重要意义。

Pyrus is mainly distributed in Eurasia and North Africa,and is generally believed to originate from the mountains in Southwest China.By briefly reviewing the main taxonomic research results of Pyrus,comparing the differences of experts from different schools on the taxonomic research of Pyrus,this paper analyzes the causes of the difficulty in morphological classification of Pyrus.The self-incompatibility of gametophytes of Pyrus leads to the differences in plant morphological classification,combined with the classification of biochemical indexes and molecular technology,the results of morphological classification were verified.Combined with the latest naming regulation“Melbourne regulation”and artificial intelligence,the prospect of Pyrus plants classification is put forward.The classification of Pyrus plants is of great significance to the protection,evaluation and utilization of Pyrus germplasm resources.
