1 Estimate based on LS means from analysis of covariance performed in SAS 9.3.
2 Numbers in the same column followed by same letter are not significantly different (P < 0.05) as determined by Tukey-Kramer’s method for pairwise comparisons.
3 Corn-strain FAW were used in all assays.
*indicates P<0.001.
