图1 阔叶红松林幼苗在不同根级以及菌根类型间细根性状的比较。AM, 丛枝菌根; C, 全碳含量; C:N, 碳氮比; D, 根直径; EM, 外生菌根; N, 全氮含量; P, 全磷含量; RTD, 根组织密度; SRL, 比根长。不同小写字母表示同一菌根类型内根级间差异显著(p < 0.05), 不同大写字母表示同一根级内两种菌根间差异显著(p < 0.05)。

Fig. 1 Comparison of fine root traits of seedlings across different root orders and mycorrhizal types in mixed broadleaf-Korean pine forests. AM, arbuscular mycorrhiza; C, total carbon content; C:N, carbon nitrogen ratio; D, root diameter; EM, ectomycorrhiza; N, total nitrogen content; P, total phosphorus content; RTD, root tissue density; SRL, specific root length. Different lowercase letters indicate significant differences among different root orders in the same mycorrhizal type (p < 0.05), and different uppercase letters indicate significant differences between two mycorrhizal types within identical root orders (p < 0.05).
