In a study of symptom development of internal rot of netted melon fruits inoculated with Pantoea ananatis group II strain SUPP1791, symptoms did not develop immediately, even when bacterial populations reached 10E6～7 cfu/g of fruit tissue. Symptoms in the placenta of the fruit were visible at 40 days post-inoculation, when the bacterial population was ca. 10E7 cfu/g for at least 10 days. Sugar content was significantly lower in symptomatic tissues than in the asymptomatic. SUPP1791 caused internal rot of fruits of several other cucurbit plants except for cantaloupe and cucumber.
