图4 不同林型岷江冷杉幼苗各器官间(A, 叶-根; B, 茎-根; C, 叶-茎)生物量的异速生长方程。所有回归模型均在α = 0.001水平上显著。p表示斜率与1.0的差异显著性。AP, 岷江冷杉原始林; BA, 红桦-岷江冷杉针阔混交林; BB, 红桦阔叶林。

Fig. 4 Allometric relationships for different dimensions (A, leaf-root; B, stem-root; C, leaf-stem) of Abies fargesii var. faxoniana seedlings in different forest types. All regression models were significant at the α = 0.001 level. p indicates a significant difference in slope with 1.0. AP, Abies fargesii var. faxoniana primary forest; BA, Betula albosinensis - Abies fargesii var. faxoniana needleleaf-broadleaf forest; BB, Betula albosinensis broadleaf forest.
