摘要： 研究表明，与对照品种晋麦53号及北京841比较，长治5608上部三叶叶夹角较小，叶面积较大，后期叶面积大，旗叶功能期长，灌浆速度快，从而使得千粒重高、穗粒数多。这为冬小麦长治5608高产、稳产性显著优于对照奠定良好的形态生理基础。同时，此研究也为指导超高产品种选育和高产栽培提供了理论参考。

Abstract: Compared with control cultivars Jinmai-53 and Beijing-841, Changzhi-5608 features smaller leaf included angle, larger leaf areas, longer flag leaf function sustain period and quicker grouting speed, therefore its 1000-grain weight is high and the grains of a ear are more. This has not only laid a good morphological and physiological foundation for firm and high grain yield, but also provided theoretical reference for high-yield breeding and high-yield cultivation.
