| 摘 要： | 采用系统聚类的方法对我国20世纪80年代以来的50个主栽玉米品种进行划分,通过密度调控,对不同穗型玉米品种粒、叶内源生理特性进行了深入探讨,试验结果如下:各穗型玉米品种同一生育时期相比较,叶片的功能强弱依次为紧凑大穗型品种掖单13、紧凑小穗型品种掖单4号、平展大穗型品种沈单7号.密度对不同穗型玉米品种叶片生理的影响

| Abstract: | different commercial maize varieties were investigated by cluster analysis.Some physiological characteristics on kernel and leaf sink of different spike types were explored in field.The main results were as follows:At the same period,the genotype order on ear leaf function showed Yedan 13>Yedan 4>Shendan 7.The planting density's influence to the different spike type of maize was different,which was Shendan 7>Yedan 13>Yedan 4.The ability of kernel to acclimatize oneself to the change of the density was different,which seemed Yedan 4>Yedan 13>Shendan 7. |
