摘　　要：研究结果表明,郑单18上中部叶片夹角小,下部叶片夹角大;叶绿素、蛋白质、可溶性糖含量高,过氧化物酶活性高,丙二醛积累少,叶片功能强,衰老慢;叶面积系数大;灌浆时间长;千粒重高,产量高于郑单958。The study result showed that corn Zhengdanl8 has a smaller intersection angle on upper and middle leaves, has a bigger intersection angle on lower leaves. Zhengdanl8 has higher content on chlorophyll, protein, soluble sugar, higher activity of peroxidease, lower accumulation on the third second aldehyde, more powerful function of leaves, lower growing old; bigger leaf area index, longer grain filling time.. The vield and thousand kernel weight of Zhengdan18 are weightier than that of Zhengdan958.
