图3. 杉木家系M1 (A)和M4 (B)吸收的外源磷的分配动态(平均值±标准偏差)。不同小写字母代表低磷条件下地上部分或根系不同处理时间吸收外源磷分配率差异达0.05显著水平, 不同大写字母代表高磷条件下地上部分或根系不同处理时间吸收外源磷的含量差异达0.05显著水平。
Fig. 3. Dynamics of the exogenous phosphorus (P) allocation in roots, stems and leaves of M1 (A) and M4 (B) for Chinese fir under different P treatments (mean ± SD). Different lower case letters indicate the significance (p < 0.05) in P allocation of different periods under low P (L-P) treatment, whereas different uppercase letters represent the significance (p < 0.05) under high P (H-P) treatment.
