图2. 杉木家系M1 (A)和M4 (B)在不同处理时间下叶、茎和根中吸收外源磷的含量(平均值±标准偏差)。不同小写字母代表低磷(L-P)条件下同一器官不同处理时间吸收外源磷的含量差异达0.05显著水平, 不同大写字母代表高磷(H-P)条件下同一器官不同处理时间吸收外源磷的含量差异达0.05显著水平。
Fig. 2. Changes in concentration of the exogenous phosphorus in leaves, stems and roots of M1 (A) and M4 (B) for Chinese fir with time for each treatment (mean ± SD). Different lower case letters represent the significant levels (p < 0.05) in phosphorus content of the same organ under low phosphorus (L-P) treatment, whereas different capital letters indicate the significance (p < 0.05) under high-?phosphorus (H-P) condition.
