摘　　要：以千重浪2号(23 g/1 000粒)和润宇1号(30 g/1 000粒)为试材,研究不同粒重北方粳稻品种的颖壳发育动态。结果表明,在颖壳发育过程中,供试品种颖壳大小和干重都表现为强势粒>中势粒>弱势粒,发育动态均呈慢快慢的变化规律;强势粒的颖壳生长最快时期为叶龄余数0.5至叶枕距+2.0时,弱势粒为叶枕距+2.0至+6.0时;对于中势粒,千重浪2号与强势粒的颖壳生长变化规律相同,而润宇1号与弱势粒的颖壳生长趋势相同。The field experiment were carried out with two japonica varieties, Runyu No.1（30 g / 1 000 g rain weight）and Qianchonglang No.2（23 g / 1 000 g rain weight）. It studied glume growth development of Northern japonica rice of different grain weight varieties. The result indicated that the size and dry weight of glume of tested cultivars were in order of superior grainsmiddle grainsinferior grains in the process of glume development, and the growth showed a sequence of slow, fast and slow variation; the fastest stage of glume growth of superior grain is at leaf remainder 0.5 to distance between pulvinus ＋2.0, yet for inferior grain, it showed distance between pulvinus from ＋0.2 to ＋0.6; for middle grains of Qianchonglang No.2, its variation of glume growth is the same as superior grain, and Runyu No.1 is the same as inferior grain.
