图4. 7个亚热带典型树种根毛属性与根属性的Pearson相关关系。HD, 根毛直径; MC, 菌根真菌侵染率; RD, 根直径; RH, 根毛出现率; RHD, 根毛密度; RHL, 根毛长度; RTD, 根组织密度; SRL, 比根长。7个有根毛树种根毛和根属性间的相关系数(对角线以下)和系统发育独立对比(对角线以上), 存在显著相关性(n = 28; *, p < 0.05; **, p < 0.01)。

Fig. 4. Pearson correlation coefficients between root hair traits and root traits of seven typical subtropical tree species. HD, root hair diameter; MC, mycorrhizal colonization rate; RD, root diameter; RH, root hair occurrence rate; RHD, root hair density; RHL, root hair length; RTD, root tissue density; SRL, specific root length. Pearson correlation coefficients (below the diagonal) and phylogenetically independent contrasts (above the diagonal) among seven functional traits for seven root hair tree species (n = 28; *, p < 0.05; **, p < 0.01).
