图3. 芦苇各器官生物量分配比例(平均值±标准误差, n = 40)。不同的小写字母表示同一水处理水平上, 不同铅处理间差异显著(p ≤ 0.05), *表示同一铅处理水平上, 淹水和干旱处理间差异显著(p ≤ 0.05)。
Fig. 3. The percentage of different organ biomass in total biomass of Phragmites australis subjected to Pb concentration in flood and dry environment (mean ± SE, n = 40). Different lowercase letters indicate significant differences (p ≤ 0.05) between Pb levels within one water treatment level, and * indicates significant difference (p ≤ 0.05) between water treatment and drought treatment within one Pb level.
