摘 要 ：供试化杀型(CHA), T型三系杂种小麦及各自亲本在旗叶一生中的净光合速率(PO、叶绿素含量(Ch1)和可溶蛋白含量(Sp)均在全展时达到最大值，以后逐渐下降。在春季生育期中群体光合速率(CAP)的变化趋势呈单峰曲线，于开花期达到最大值。与亲本和对照相比，杂种小麦在生育期间于上述性状上多表现正向优势，且优势随生育进程不断增

Abstract:During flag leaf growth span， the photosynthetic rate (Pn)，chlorophyll Content (Chl) and soluble protein content (Sp) of flag leaf all reached the highest values at the leaf full expansion for tested hybrid wheats and their parents，then gradually declined. During spring growth stage，the canopy
