Fig 1. Mycorrhizal colonization (MC) of R. pseudoacacia was affected by Pb stress levels.

Fig 1

NM, non-inoculated control; Fm, inoculated with F. mosseae; and Ri, inoculated with R. intraradices. The results are reported as the mean (n = 6) ± SD. The same letter indicates no significant difference among treatments (Duncan’s test, P < 0.05). Two-way ANOVAs were used to determine the significance of the effects of the Pb level (Pb), AMF inoculation (AMF), and their interactions (Pb × AMF) on the MC of black locust seedlings, as shown in S1 Table.
