摘　　要：梨作为我国大宗果树种类之一,具有较高的营养价值和保健功效,深受国内外消费者的欢迎。梨为伞房花序、多花类型,花序形成花朵数量对果实有一定的影响。在生产中常采用疏花疏果措施,来调控树体坐果量,使梨树达到合理的负载量标准,从而保证梨树的产量及品质。因而,了解花序形成机制,对提高梨果产量及品质有一定的帮助。本文从花序演变趋势、花序发育过程、花序坐果位置、内源激素对花序成花的影响及相关基因对成花的调控等方面进行综合论述,并对今后梨花序形成研究方向提出了设想,旨在为今后梨花序形成研究提供思路。Pear is one of the major fruit in China and favorite by domestic and foreign consumers due to its nutritional value and health efficacy.Pear flower is corymb inflorescence and belongs to the multi-flowered type.Fruit setting rate of inflorescence has significant influence on the yield of fruit trees.Artificial control of flowers and fruits is a measure to regulate the amount of fruit set in the tree,to ensure the yield and fruit quality maximizing the commercial profile.Understanding the mechanism of inflorescence formation is of interest to increase fruit yield and improve fruit quality.This paper reviews the evolution of inflorescence,the process of inflorescence development,fruit setting position of inflorescence,effects of endogenous hormones on floral formation,and regulation of related genes on floral formation,etc.Moreover,the future prospective is proposed,in order to provide ideas for the research on pear inflorescence formation.
