| 摘 要： | 采用盆栽方法研究了光照强度对不同玉米品种生长发育和产量的影响。结果表明：2个玉米品种在全生育期遮光条件下株高、穗位增高，单株叶面积减小，开花日期延后，雄穗变短；干物质在根、茎、叶、穗等器官内的累积量降低，干物质在各器官中的分配存在差异；由于遮光处理减少行粒数和千粒重，导致玉米单株产量降低，“瑞秋”遮光处理比ck减产26．1％～28．1％，“郑单958”遮光处理比ck减产43．4％。45．9％。说明在单株水平上，“瑞秋”比“郑单958”具有较强的耐荫性。

| Abstract: | The effects of light intensity at full growing stage on the growth and yield of different maize varieties were studied with the method of pot cultivating.The results showed that shading at full growing stage increased plant height and ear height,and retarded flowering date,but decreased leaf area per plant,tassels length and lower stem diameter.Accumulation of dry matter in root,stem,leaf and ear was decreased when shading at full stage,dry matter distributive rate of every apparatus significantly differed.... |
