【摘要】 梨的原种起源于第三纪甚至更古的中国西部或者西南部的山区。从梨的发祥地北上向东移动,形成了以中国大陆为次生中心的东亚梨种群(东方梨)。向西移动中,形成了两个次生中心,产生了西方梨种群。现代分子生物学方法在梨系统关系研究中的应用,初步揭示了梨属植物的演化规律,将为最终建立反映梨属进化历史的分类体系奠定基础。更多还原

【Abstract】 The basic Pyrus stock arose during the Tertiary period or even a more ancient period in the mountainous regions in western and southwestern China. Three secondary centers of Pyrus species diversity for the genus formed. One was the Chinese center, where Oriental pears have evolved. The others were the central Asian, and the Near Eastern/Asia Minor centers, where Occidental pears speciated. The use of molecular biological methods has provided some new information about the evolution of Pyrus, which will be of help for phylo-genetic systematics of Pyrus.更多还原
