| 摘 要： | 应用徒手切片和石蜡切片，系统观察了玉米穗、粒发育期间穗轴及小穗柄内维管束的分化、发育和联络，测量了不同维管束的横截面积；收集测定了果穗发育过程中果柄伤流液；探讨了穗、粒维管束的发育与穗粒库容的关系。结果表明，果穗内维管束联络系统的分化发育与穗分化相一致；穗柄—穗轴—籽粒的维管联络在双小穗期初步建成，

| Abstract: | In recent years, most works about grain yield forming focused on sink-source relationship, and set up a series of theory and technique of high yield using in crop production. There were few studies on sink-flow, which is important for grain yield forming. The spike vascular bundle is an essential or |
