Comparison of the effect of seed treatments with Acidovorax citrulli
AAC00-1ΔhrcC (type III secretion system mutant), A. avenae (AAA 99-2), or 0.1 M
phosphate-buffered saline (PBS, negative control) on bacterial fruit blotch (BFB)
seedling transmission for watermelon seed naturally infested with A. citrulli. Data
points represent the mean BFB seedling transmission percentage of two experiments
(n = 100 seeds/treatment) and the lines represent the standard error of the
means. B, Bar chart of area under disease progress curves (AUDPCs) calculated
for naturally infested seed treated with AAC00-1ΔhrcC, AAA99-2, or PBS. Bars
represent mean AUDPC values and lines indicate standard error of the means.
Treatments with different letters are significantly different according to Tukey-
Kramer’s honestly significant difference.
