Relationships Between Yield and Crown Disease of Sweet Corn Grown in the Willamette Valley of Oregon

Fig. 3. Mean crown grayscale (A), mean stalk node grayscale (B), and ear weights (C, D) of sweet corn plants sampled from commercial fields in the Willamette Valley when Fusarium species were detected or absent in the crown (C) or stalk node (D). Foxy = Fusarium oxysporum, present in 80 crowns and 58 nodes of 305 plants sampled, Fvert = F. verticillioides, present in 39 crowns and 46 nodes, All Fusaria = any Fusarium species, present in 136 crowns and 120 nodes. Within each bar graph, * indicates significant differences at P = 0.05 and ** at P = 0.01 between adjacent black and gray bars, and ŧ indicates significant differences at P = 0.05 and ŧŧ at P = 0.01 compared to the "no Fusarium recovered" group ("All Fusaria," gray bar) based on two-sample t-tests. Error bars represent pooled error from a two-sample test comparing adjacent black and gray bars.
