图2. 开阔和林下生境的4种被子植物和5种蕨类植物的气孔密度和气孔长度(平均值±标准误差)。物种缩写同表1; A, F分别代表被子植物(n = 4)和蕨类植物(n = 5); U, O分别代表林下生境(n = 6)和开阔生境(n = 3); **, p < 0.01; *, p < 0.05。

Fig. 2. Stomatal density (SD) and stomatal length (SL) for 4 angiosperms and 5 ferns in open and understory habitats (mean ± SE). Abbreviations of species name see Table 1; A and F represent angiosperms (n = 4) and ferns (n = 5), respectively; U and O represent plants in understory (n = 6) and open habitats (n = 3), respectively; **, p < 0.01; *, p < 0.05.
