图1 内蒙古温带草地不同功能群和草地类型植物叶片(Le)、茎(St)、生殖器官(Re)、细根(Fr)和粗根(Cr)平均N含量(A)、P含量(B)、N:P (C)、比叶面积和比根长(D)以及叶片和细根的组织密度(E)的比较。用单因素双差分析(Tukey post hoc)检验不同功能群和草地类型之间的差异; 显著性差异(p < 0.05)用不同字母标记。误差棒为标准误差。

Fig. 1 Comparisons of leaf (Le), stem (St), reproductive structure (Re), fine root (Fr) and coarse root (Cr), mean N concentrations (A), P concentrations (B), N: P ratios (C), specific leaf area, specific root length (D) and tissue density of leaves and fine roots (E) among different function groups and vegetation types in Inner Mongolia grassland. Differences between each group were tested using a One-Way ANOVA with a Tukey post hoc test of significance; significant differences at p < 0.05 are indicated by different letters. Errors bars are standard errors. SLA, specific leaf area; SRL, specific root length.
