摘　　要：源库关系研究在作物产量和品质形成中具有重要的理论研究和技术应用价值。随着作物遗传育种、植物生理和分子生物学等多学科的交叉融合,源库关系研究近年来整合运用分子生物学技术、植物激素信号转导等众多新技术和新方法取得了重要进展。本文综述了源库关系理论和源库关系调控两方面研究进展,重点阐述了糖代谢、激素调控源库关系的机理,分析通过栽培措施协调源库关系提高产量的机理。同时结合热带重要经济作物橡胶树的排胶机理与调控研究进展,论述乙烯利刺激和割胶处理调节源库分配与橡胶树产量形成之间的关系,以期推动天然橡胶源库关系理论研究,为排胶调控技术创制提供技术指导。The study of source/sink relationship has important theoretical research and technical application value in crop yield and quality formation.With the interdisciplinary integration of crop genetics and breeding,plant physiology and molecular biology,the study of source-sink relationship has made important progress in recent years by integrating molecular biology techniques,plant hormone signal transduction and many other new technologies and methods.In this paper,the research progress is reviewed from two aspects:source/sink relationship theory and regulation.The mechanism of glucose metabolism and hormone regulating source/sink relationship was emphasized,and the mechanism of cultivation measures improving yield by coordinating source/sink relationship was analyzed.Combined with the research progress on the mechanism and regulation of rubber trees,an important tropical cash crop.This lay a foundation for the theory of source/sink relationship in natural rubber industry and provide technical guidance for the creation of rubber latex flow control technology.
