摘　　要：为明确玉米近穗位叶有关性状与果穗经济性状的相关性,本试验对12个玉米品种穗位叶的长度和叶形值、近穗位叶茎叶夹角、叶绿素含量与果穗直径、穗行数及产量的关联性进行了分析。结果表明,穗位叶的长度与果穗直径有着密切的关联性,即穗位叶长度较长的品种果穗粗;当叶形值为8.35时,果穗直径、穗行数、产量均达到最大值;近穗位叶的茎叶夹角与果穗直径、穗行数及产量成明显的相关性,即茎叶夹角大的品种果穗直径较小,穗行数较少,产量较低;抽雄期叶片叶绿素含量与产量成正相关性。In order to clarify the correlation between the traits related to the leaf near ear position of maize and the economic traits of the ear,this experiment analyzed the correlation between length of leaves at ear position,leaf shape value,stem-leaf angle of leaves near ear position,chlorophyll content and ear diameter,number of ear rows and yield.The results showed that there was a close correlation between the length of leaf at ear position and the ear diameter,and that was,varieties with longer leaf length at the ear position had thicker ears.When the leaf shape value was 8.35,the ear diameter,number of ear rows and yield all reached the maximum value.The stem-leaf angle near the ear position showed obvious correlation with ear diameter,number of ear rows and yield,that was,varieties with larger stem-leaf angle had smaller ear diameter,fewer ear rows and lower yield.There was a positive correlation between chlorophyll content of leaves and yield at tasselling stage.
