图1 12个树种的根系性状及菌根类型效应(平均值±标准误)。AM, 丛枝菌根; EcM, 外生菌根。Am, 色木槭; AT, 青楷槭; BP, 白桦; EA, 卫矛; FM, 水曲柳; JM, 胡桃楸; LG, 落叶松; PA, 黄檗; PD, 山杨; PK, 红松; QM, 蒙古栎; UD, 春榆。不同小写字母代表不同树种间差异显著(p < 0.05)。括号内的百分数为不同菌根树种的变异系数; *代表混合效应模型中菌根类型效应的显著性水平: **, p < 0.01; ***, p < 0.001。

Fig. 1 Root traits among 12 tree species and the effect of mycorrhizal types on root traits (mean ± SE). AM, arbuscular mycorrhiza; EcM, ectomycorrhiza; N, nitrogen; P, phosphorus. Am, Acer mono; AT, Acer tegmentosum; BP, Betula platyphylla; EA, Euonymus alatus; FM, Fraxinus mandshurica; JM, Juglans mandshurica; LG, Larix gmelinii; PA, Phellodendron amurense; PD, Populus davidiana; PK, Pinus koraiensis; UD, Ulmus davidiana var. japonica; QM, Quercus mongolica. Different lowercase letters indicate significant differences among different tree species (p < 0.05). The percentage in parentheses represent the coefficient of variation on different mycorrhizal tree species; * indicate the significance levels of mycorrhizal type effects in the mixed effects model: **, p < 0.01; ***, p < 0.001.
