| 摘 要： | 对生产中正在种植的7个小偃小麦新品种顶三叶功能期、灌浆速度、籽秆比、产量结构等生理特性进行了研究。结果表明：小偃107叶功能好，叶面积系数最高。小偃6号灌浆速度最快，籽粒饱满。小偃22籽杆比最大，产量最高。产量与穗数、穗粒数、千粒重、籽杆比、叶面积系数皆呈正相关，株高与籽杆比负相关。

| Abstract: | The numbers of green top three leaf and coefficient of leaf area,the filling speed,the grain-straw ratio,the yield and its composing factors of 7 Xiaoyan new wheat varieties were studied. The result indicates:the leaf functions of Xiaoyan 107 are good,and its leaf-area coefficient is the highest. The filling speed of Xiaoyan No.6 is the quickest,its seed grain is full. The grain-straw ratio and the yield of Xiaoyan 22 arc the highest. It presents positive correlation between the yield and the spikes,grains,grains weight,the grain-straw ratio,the leaf-area coefficient.Plant height is negatively related with grain-straw ratio. |
