marginally significantp = .1
Comparing plant species, we found a marginally significant plant species effect with Dogbane showing longer SRL compared Ironweed (Figure S2 ; F 3,4.56 = 3.935, p = .1). 3.3 Mycorrhizal growth response Overall, plants grew significantly larger with AMF than in the sterile treatment, both in terms of aboveground (rank: p < .0001, F 1,175 = 312.98; permutation: p < .0001) and belowground (rank: p < .0001, F 1,178 = 201.16; permutation: p < .0001) biomass.
