Fig. 1. Mean mycorrhizal colonization levels per treatment of those plants grown in the presence of mycorrhizal inoculum. It was observed that 95% of all plants inoculated for this experiment demonstrated some level of mycorrhizal infection, with no evidence of colonization observed in the nonmycorrhizal treatments. Error bars indicate one standard error. Means with letters in common are not significantly different (P > 0.05).
