图3. 不同处理对根瘤生物量响应比(RR)(A)和根瘤投资(B)的影响(平均值±标准误)。图A中,虚线位置代表RR = 1, 如果误差线没有跨越虚线表示处理与对照存在显著差异(p < 0.05)。*, p < 0.05; **, p < 0.01; ***, p < 0.001。 |
Fig. 3. Responses of the nodule biomass response ratio (RR)(A) and investment to nodulation (B) under different treatments (mean ± SE). In Fig. A, response ratio values with error bars not overlapping RR = 1 (horizontal dotted line), indicate significant difference between treatment and control (p < 0.05). *, p < 0.05; **, p < 0.01; ***, p < 0.001. |
