Table 1. Biomass, leaf area, and root traits in faba bean, wheat, and their mixture grown in the absence (–myc) or presence (+myc) of arbuscular mycorrhizal fungi.

Cs, cropping system (faba bean, wheat, mixture); M, absence or presence of AMF.

^# In parenthesis percent contribution of faba bean on the total of the mixture. Data are means of 5 replicates.

^†, *, ** and *** indicate significant differences at P ≤ 0.10, 0.05, 0.01, and 0.001, respectively; ns indicates differences not significant.
