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、籽杆比、产量结构等生理特性进行了研究。结果表明 :小偃 1 0 7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 2 2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。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 are 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.
