图2. 不同物种组合、密度、种子比例处理下互花米草(Sa, A、B)、海三棱藨草(Sm, C、D)、芦苇(Pa, E、F)种子的萌发率及平均萌发时间(平均值±标准误, n = 4)。不同大写字母表示不同密度处理间存在显著差异(p < 0.05), 不同小写字母表示同一物种组合及密度下不同种子比例间存在显著差异(p < 0.05)。
Fig. 2. Germination rate and mean germination time of Spartina alterniflora (Sa, A, B), Scirpus × mariqueter (Sm, C, D), Phragmites australis (Pa, E, F) seeds in different species combination, density and seed proportion treatments (mean ± SE, n = 4). Different uppercase letters denote significant differences between different density treatments (p < 0.05). Different lowercase letters denote significant differences among different seed proportion treatments of the same species combination and density (p < 0.05).
