Fig 4. Interacting effects of varying light conditions, AMF and rhizobia on the number of produced seeds per plant (a) and germination rate (b,c).

Bars are means + s.e. 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. Different letters indicate statistically different means following Tukey’s post-hoc test (P<0.05).
