图1. 淹水和干旱生境下铅污染对芦苇地下器官和地上子株数的影响(平均值±标准误差, n = 40)。不同的小写字母表示同一水分处理水平上, 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. 1. Effects of Pb pollution on growth of below-ground organs and abundance of above-ground offspring shoots of Phragmites australis 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.
