摘　　要：植物韧皮部卸载包括一系列复杂的过程,韧皮部卸载在园艺植物(果树、蔬菜、观赏植物)同化物的运输和分配中具有重要作用。本研究概述了韧皮部卸载的主要途径,并重点综述了韧皮部卸载在园艺植物生长发育方面的主要研究成果,内容包括:①韧皮部运输的主要糖分物质;②韧皮部卸载方式;③韧皮部卸载研究方法;④园艺植物韧皮部卸载研究。随着研究的深入和新技术的出现,园艺植物韧皮部卸载过程中涉及的关键酶与蔗糖转运蛋白等需得到更深入地阐释,进一步助力解析植物韧皮部卸载参与园艺植物生长发育的分子调控机制,并有望为更多的植物韧皮部卸载研究提供新的思路。Phloem unloading contains a series of complex processes.Phloem unloading plays an important role in the transportation and distribution of assimilates in horticultural plants(fruit trees,vegetables,ornamental plants).This study summarizes the main ways of phloem unloading,and focuses on the main research results of phloem unloading in the growth and development of horticultural plants,including:(1)the main sugar substances transported by phloem;(2)phloem unloading mode;(3)research approaches for phloem unloading;(4)research on phloem unloading in horticultural plants.The key enzymes and sucrose transporters involved in phloem unloading process need further clarification with in-depth research combining the emergence of new technologies,which will help to further elucidate the underlying molecular regulation mechanism of phloem unloading during the key economic and ornamental traits formation in horticultural plants,as well as to provide new ideas for detail research on phloem unloading in other plants.
