mean BFB seedling transmission of 82 and 76.5%, respectively
(Table 1). The mean A. citrulli populations per seed for
these lots were 3.5 × 104 and 2.8 × 104 CFU/seed, respectively
(Table 1). The pistil-inoculated seed lots 3 and 4 displayed mean
seed germination of 80 and 72%, respectively, and BFB seedling
transmission of 74 and 75%, respectively (Table 1). A. citrulli
populations were 4.5 × 104 and 1.8 × 104 CFU/seed for seeds from
lots 3 and 4, respectively (Table 1). A. citrulli colonies were not
recovered from seeds from the negative control lots whose stigmas
were treated with PBS, and samples from these lots displayed
0% BFB seedling transmission (data not shown).
