FIG. 2.

Interaction set 1 (Fusarium verticillioides, F. subglutinans, and F. proliferatum) mean colony area values of solo control or secondary colonizers on the BOA-amended medium (a) and on the BOA-free medium (b). Solo control, growth of a species on previously uncolonized medium; primary col., growth of secondary colonizer following F. verticillioides, F. subglutinans, or F. proliferatum as indicated. Error bars indicate standard errors. Tukey-Kramer HSD tests were used to compare mean colony area values of the same species in different treatments. The same letter above two bars indicates that there is no significant difference between means.
