摘要： 摘要：以中筋小麦豫麦49和弱筋小麦豫麦50为材料，采用盆栽方法研究了40%FC、60%FC和80%FC对旗叶和籽粒中谷氨酰胺合成酶（GS）籽粒产量的影响。结果表明：旗叶中GS活性较籽粒中GS活性高，不同水分处理下豫麦49叶片在籽粒形成和灌浆盛期GS活性表现为60%FC>80%FC>40%FC，其它时期表现为80%FC下最高，40%FC最低，其籽粒和豫麦50叶片和籽粒GS活性均以80%FC下最高。两个品种的产量以80%FC最高，40%FC最低，60%FC居中。且旗叶和籽粒GS活性在籽粒灌浆盛期与产量都达到了极显著水平。

Abstract: Abstract：In order to understand the effects of 40%FC、60%FC和80%FC on Glutamine Synthetase (GS) activity of flag leaves and grain and quality of winter wheat with specialized end-uses,pot experiments were carried out.The results showed that GS activity in flag leaf was Higher than in grain,he activity among three water treatments showed: In grain formation and filling, GS activity in flag leaves showed: 60%FC>80%FC>40%FC,In other stage showed that: 80%FC>60%FC>40%FC with Yumai 49. The GS activity of grain of Yumai 49 and the leaves、grain of Yumai 50 showed: 80%FC>60%FC>40%.The highest grain yield in the 80%FC treatment and 40%FC had the lowest grain yield. There was a significant correlation between GS activity of flag leaves and grain and grain yield during the middle stage of grain filling.
