Fig. 6 Germination rate (A) and survival rate (B) of 12 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 replicates, which was originally 9 but was reduced in some cases due to accidental disturbances by animals. Upper row: arbuscular mycorrhizal trees. Bottom row: ectomycorrhizal trees.
