图4 玉米生理成熟后茎秆基部节间力学强度的变化 图A、C、E 为河南新乡夏玉米, 图B、D、F 为新疆奇台春玉米; RPS: 穿刺强度; CS: 压碎强度; BS: 弯曲强度。图中不同小写字母分别表示同一样点不同取样期在0.05 水平下的差异显著。

Fig. 4 Changes in mechanical strength of maize basal internode after physiological maturity Fig. A, Fig. C, and Fig. E show summer maize in Xinxiang, Henan. Fig. B, Fig. D, and Fig. F show spring maize in Qitai, Xinjiang. RPS is rind penetration strength, CS is crushing strength, and BS is bending strength. Values within the same sampling location indexed with different lowercase letters are significantly different at P < 0.05.
