图2 玉米果穗上不同部位的百粒重 Upper: 果穗上部籽粒; Middle: 果穗中部籽粒; Basal: 果穗下部籽粒。同一试验穗上不同部位间比较, 柱上字母不同表示在 P <0.05水平上差异显著。
Fig. 2 100-kernel weight of kernels at different positions on a maize ear Upper: the kernels at the upper position on an ear; Middle: the kernels at the middle position on an ear; Basal: the kernels at the basal position on an ear. Bars superimposed by different letters are significantly different at P <0.05 level within the same experiment.
