摘　　要：株型是园林植物的重要观赏性状,培育丰富的观赏性状是园林植物的育种目标之一。莲作为我国重要的园林植物,其理想株型育种应向高大型和极微型2个极端株型发展。本研究对莲株型调控的细胞学基础、生理机制、分子机理进行了系统地综述,提出了深入探究茎顶端分生组织、居间分生组织的发育模式及基因调控机理,挖掘GAs、AUX在合成和信号传导过程中的关键基因、利用分子标记技术开发莲株型相QTL位点和相关基因精准定位的未来研究方向。Plant type is an important ornamental trait of garden plants,and cultivating abundant ornamental traits is one of the breeding goals of garden plants.As an important garden plant in China,Nelumbo nucifera's ideal plant type breeding should be developed into two extreme plant types:high,large and extremely small.In this study,the cytological basis,physiological mechanism and molecular mechanism of N.nucifera type regulation were systematically reviewed.The future research directions of exploring the development model and gene regulation mechanism of stem apex meristem and intermediate meristem,mining the key genes of GAs and AUX in synthesis and signal transduction,and exploiting the QTL locus and related genes accurately by using molecular marker technology were proposed,in order to provide references for the development and utilization of N.nucifera germplasm resources.
