图6 不同氮肥处理下小麦植株地上部全部营养器官的平均干物质运转量(A)、运转率(B)和对籽粒贡献率(C) 各箱体中, 实线表示中位数, 虚线表示平均值。箱体上方不同字母表示处理间差异显著(P < 0.05)。

Fig. 6 Amount (A), efficiency (B), and contribution rate of dry matter remobilization to grain (C) averaged over all vegetative organs and water treatments of wheat shoots under different N supplies In the box, solid lines represent the median while dashed lines represent the average. Data were also analyzed by one-way ANOVA, different letters above the boxes indicate significant difference at P < 0.05.
