Boxplots and means (black rhombus) of ratios between (a) DON3G and DON, (b) 3+15-AcDON and DON, (c) 3+15-AcDON + DON3G and DON, (d) α-ZEL and ZEN (mol%) in forage maize samples of four different cultivars (Cv I–IV). Five statistics are represented in each boxplot from bottom to top: the smallest observation, lower quartile, median, upper quartile, and largest observation, respectively. Different letters describe significant differences between cultivars for each ratio (p ≤ 0.05). The p-values describe significant or insignificant differences of mean ratios from zero. DON = deoxynivalenol; DON3G = deoxynivalenol-3-glucoside; 3+15-AcDON = sum of 3- and 15-acetyl-deoxynivalenol; ZEN = zearalenone; α-ZEL = α-zearalenol. n = 120.
