| 摘 要： | 选用经多年筛选抗感程度较稳定的１０个小麦品种，于小麦拔节期对其旗叶中１７种游离氨基酸含量进行了全面测定。应用主成分分析方法研究了多处游离氨基酸中影响品种抗蚜性的主要氨基酸种类，并对游离氨基酸含量与品种抗蚜性的关系进行了探讨。结果表明：小麦品种中谷氨酸、丙氨酸、赖氨酸、天冬氨酸的含量与麦长管蚜的内禀增长率呈正相关；而亮是亮氨酸、脯氨酸、缬氨酸的含量与麦长管蚜的内禀增长率呈负相关。说明小麦品种中前４种

| Abstract: | In this paper,ten wheat varieties of different resistances were studied.Their contents of seventeen species free amino acids were determined at jointing stage.The analysis results showed that the resistance of winter wheat to Macrosiohum aven ae Fab is higher when contents of Leucine,Isoleucine,Proline,Valine are greater; the resistance of winter wheat to M.ave nae is lower when contents of Glutamate,Alanine,Lysine,Aspartate are higher. |
