摘　　要：豆梨(Pyrus calleryana)蔷薇科梨属落叶乔木,原产于中国,集观赏、药用、嫁接砧木为一体。豆梨对外界环境适应性强,最初被美国发掘并培育出了一系列优良观赏品种,我国对豆梨观赏资源的研究利用现多以反引种为主。从豆梨的生物学特征和开发利用价值入手,并对良种引进、繁育栽培、抗逆性以及叶色变化机理4个方面的研究现状进行了综述,提出了存在的问题,展望了其广阔的应用前景。Pyrus calleryana,a deciduous tree in Rosaceae,native to China.It is a kind of grafting rootstock for ornamental and medicinal purposes and has great potential for development.In addition,it is highly adaptable to the external environment,and is initially discovered and cultivated in the United States.Now,the research and utilization of P.calleryana ornamental resources in China are mainly in the form of reverse introduction.We introduced biological characteristics and development and utilization value of P.calleryana,summarized its research status on four aspects such as fine species introduction,breeding culture,stress resistance and leaf color changes mechanism,posed existing problems,prospected the application for the future.
