小麦穗部器官发育与幼穗分化发育时期早晚有很大关系。穗分化时一些栽培措施也能影响器官分化强度。所以在生产上根据穗分化各时期与叶龄的对应关系,从外部形态上掌握小麦幼穗分化发育过程,采取相应的措施促进穗部各器官的发育,可以获得高产。我们在适期播种条件下对辽宁省几个春小麦品种进行了初步研究。一、材料和方法试材为辽宁省几个主要春小麦品种:铁春1号、辽春10号、辽春9号,外加春小麦新品系87鉴5。1991年3月30日播于辽宁省农科院
The development of wheat spike organs has a great relationship with the development of young spike differentiation. Some cultivation measures during spike differentiation can also affect organ differentiation intensity. Therefore, according to the corresponding relationship between the stages of ear differentiation and leaf age in production, we can master the differentiation and development of wheat spikes from the external morphology, and take corresponding measures to promote the development of various organs of the ear to obtain high yield. We conducted a preliminary study of several spring wheat varieties in Liaoning Province under suitable sowing conditions. MATERIALS AND METHODS The test material was selected from several major spring wheat varieties in Liaoning Province: Tiechun 1, Liaochun 10 and Liaochun 9, plus 87 new spring wheat lines.5 On March 30, 1991, ASTRI
