| 摘要: |
| 冬小麦灌浆期间籽粒蛋白质各组分形成时间不同,清蛋白和球蛋白主要在籽粒形成期和灌浆前期形成;醇溶蛋白和谷蛋白主要在灌浆期形成,直至成熟后仍有增长。增加施N量,或中后期追N或喷N等措施对增加醇溶蛋白和谷蛋白效果显著,对籽粒的加工品质有所改善,但对清蛋白和球蛋白含量影响较小,对改善营养品质作用有限。 |

| Abstract: |
| In the filling duration of winter wheat,the formation time of the component parts in grain protein differs from each other. Grain Albumin and Globulin contents are mainly from the grain formation mainly formed in the whole filling duration and even continue to grow after the grain maturity. Increasing N of todressing N in thd middle or later of grain growth,of spraying N willeffectively promote thd percentage processing grain quality. But these measures will have little effects upon the percentage promotion of grain Albumin and Gluteline contents as well as the improvement of nutrition qualities. |
