| 摘要: |
| 通过两年对普通小麦小偃6号和小偃107、硬粒小麦4286，在播前、返青、拔节和抽穗4个关键时期施氮，研究了小麦籽粒粗蛋白含量及其组分含量的变化。结果表明，施氮对普通小麦的调节效应大于硬粒小麦。随施氮时期推迟，各品种蛋白质含量呈递增趋势，但增加程度不同。蛋白质组分中清蛋白和谷蛋白随施肥时期推后，呈递增趋势，但球蛋白以拔节期施肥含量最高，醇溶蛋白以拔节期或返青期施肥含量最高。 |

| Abstract: |
| The changes of protein content and protein fractions in different varieties were studied based on nitrogen applying stages during the development of wheat in 1992 and 1993.The result showed that the protein content,including albumine and giutanine content,increased with the delay of nitrogen applying stage,but the maximum increase of globline and prolamine was in the stage of return green and jointing periods,respec-tively,Among the varieties tested existed significant difference in the contents of theprotein and its fractions. |
