a
C, D, H, and F, control, damage, heat, and flood treatments, respectively. The presence of a letter (C, D, H, or F) indicates a significant difference between the two plants compared for that group, while “none” indicates no significant differences. Statistical analyses were performed by two-way ANOVA. —, no data were available because infectivity titers were below the method's detection limit.
