Figure 1.

Fungal contamination of portions of the wheat plants evaluated by morphological analysis, shown as percentage of infected plants on the total plants. The contamination of different treatments (blank; FG = wheat inoculated with F. graminearum; FG oat = uncontaminated wheat in proximity of oat kernels contaminated with F. graminearum) was shown at different stages of plant growth. In 2007 samples derived from eight plants for replicate, while in 2009 samples derived from 24 plants per replicate. Different letters within each group indicate statistically significant differences between treatments. Same letters within each group indicate not statistically significant differences between treatments. (a) 1st year experiment (2007); (b) 2nd year experiment (2009).
