摘　　要：小麦开花后各器官的硝酸还原酶和谷氨酰胺合成酶均具有一定的活性 ,旗叶中硝酸还原酶和谷氨酰胺合成酶活性最高。开花后旗叶和根系硝酸还原酶和谷氨酰胺合成酶活性逐渐降低 ,颖壳和籽粒中硝酸还原酶和谷氨酰胺合成酶活性先升高 。After flowering, the activities of nitrate reductase (NR) and glutamine synthetase (GS) in different organs of wheat were recorded, especially in flag leaf, their activities were highest. The activities of NR and GS in flag leaf and root gradually reduced after anthesis, but in husks and grains first raised, then reduced.
