| 摘 要： | 检测了三唑酮拌种对３个小麦品种京双１６、丰抗８号、燕大１８１７二叶期幼苗叶片中还原糖含量、游离氨基酸种类与含量的影响。结果表明：还原糖含量提高２０．４６％～３１．１２％；天门冬氨酸含量分别降低４９．６％，１８．８％和１５．５％。苏氨酸、异亮氨酸、亮氨酸、苯丙氨酸、赖氨酸、精氨酸等含量降低３．３％～１００％，缬氨酸含量却提高２９．７％～８４．１％，丝氨酸等９种氨基酸未呈现出一致性变化。１７种氨基酸总含量分别降低２８．３％，１４．９％和４．２％．

| Abstract: | The result showed that the reducing sugar contents increased 20. 46%～31.12% in the seedlings leaves of wheat seeds (three cultivars: Jingshuang 16, Fengkang 8,and Yanda 1817) treated with triadimefon. Asp. contents reduced 49. 6 %, 18. 8 %, and 15. 5 %, total 17 free amino acid reduced 28. 3%, 14. 8% , and 42. %, in leaves of treated seedlings of the above three cultivars respectively. Also, contents of Thr. , Ile. Leu.,Phe., Lys., and Arg. reduced 3. 3 % ～100%, but Val. contents increased 29. 7～84.1%.Contents of Ser. and other free amino acid did not reveal similar changes in treated and untreated leaves of the three wheat cultivars. |
