摘 要 ：1985—1986年在中等肥力下对3种不同叶夹角玉米杂交种的研究表明,在本试验的密度范围中,平展叶中单2号产量与密度呈显著负相关(r=-0.779~* n=9),直立叶(无叶舌)中单2号产量与密度呈极显著正相关(r=0.970~(**) n=9),上挺叶 Mo17/Lg×黄早四产量与密度呈显著正相关(r=0.797~(**) n=9)。在光合性状与产量关系研究中发现,平展叶中

Abstract:This study was carried out in 1985 and 1986,in Taiyuan,Shaanxi province.Theresults could be summerized as follows:In the range from proper to high plant densities,the correlation coefficients between yields and densities for Zhong Dan No.2 with flat leaf was significantlynegative(r=-0.779~*, n=9),hi
