Different letters within a column indicate statistical significance at p < 0.05. FL, first-order fine-root length (mm); FD, first-order fine-root diameter (mm); FA, first-order fine-root area (mm2); BR, branching ratio; BI, branching intensity. No, number of individual fine roots; CV, coefficient of variation.
