图3 基于LFe 效应值的32个玉米品种的聚类分析及性状变异 A表示基于不同性状的LFe效应值对32份玉米杂交种的聚类;B表示不同组中的16个性状在正常Fe和低Fe水平下的变化。图例中1、2、3、4和5代表不同组别;“*”表示2 Fe素处理差异显著（P<0.05）;不同小写字母代表同一Fe水平下组间差异显著（P<0.05）

Fig.3 Clusters of 32 maize varieties and the variations analysis between different traits based on LFe condition A means clustering of 32 maize varieties based on LFe effect of different traits; B means change patterns of ten traits in the different groups under NFe and LFe levels in the legend. 1, 2, 3, 4 and 5 represent different groups; Significant difference between two Fe treatments is indicated by "*" (P <0.05); Significant difference between groups in ferritic level is indicated by different small letters (P < 0.05)
