Fig. 1.

Fresh weight (FW) of V. lychnitis inoculated with a single endophyte (white bars; NM) and subject to inoculation with AMF and endophytic fungi (gray bars; M). Single stars indicate statistically significant differences between V. lychnitis inoculated with both types of fungi and the M control. Double stars indicate statistically significant differences between the NM control and plants inoculated with a single fungal endophyte. Biomass production was lower in NM than M plants in all of the setups tested. Statistical significance was assessed by the t test, P ≤ 0.05. Whiskers represent SD from N = 3–22 (a). Two-way ANOVA was performed to evaluate the effect of double inoculation on plant biomass (b)
