Fig 2. Interacting effects of varying light conditions, AMF and rhizobia on aboveground (a, b, c) and belowground biomass (d, e, f).

Bars are means + s.e. Different letters indicate statistically different means following Tukey’s post-hoc test (P<0.05). Only significant interactions are given as means of the corresponding factorial combinations, thus (a) and (d) include all rhizobial treatments, (b) and (e) include all mycorrhizal treatments and (c) and (f) include all light treatments. Only tests with a significant interaction between two factors are followed by a post-hoc test.
