Fig. 7 Dry weight of the entire seedling (A), shoot length (B), and
colonization rate of mycorrhizal fungi (C) of the tested tree species on
brown rot logs, white rot logs, and soil. Different lowercase letters on
the boxes indicate a significant difference across the substrates
(Steel-Dwass test, P < 0.05). Ns indicate no
significant differences across the three substrates (Steel-Dwass test,P > 0.05). Numbers indicate the number of replicate
seedlings used for the measurements. Upper row: arbuscular mycorrhizal
trees. Bottom row: ectomycorrhizal trees. Dry weight was not measured
for Clethra and Betula seedlings because they were too
lightweight.
