Influence of Developmental Stage on Susceptibility of Tomato Fruit toPseudomonas syringaepv.tomato

Getz, S., Stephens, C. T., and Fulbright, D. W. 1983. Influence of developmental stage on susceptibility of tomato fruit to Pseudomonas syringae pv. tomato. Phytopathology 73:36-38. Tomato flower buds, flowers, and fruit were inoculated with fruit decreased as diameter at the time of inoculation increased. Lesions did Pseudomonas syringae pv. tomato (= P. tomato) at various developmental not develop on inoculated pink or red fruit. In field studies, lesions did not stages in greenhouse and field studies. In greenhouse studies, inoculation at develop on fruit inoculated when >3 cm in diameter. These results indicate the open corolla stage resulted in a significant decrease in marketable yield that uninjured tomato fruit are most susceptible to infection by P. syringae compared to the uninoculated control. Lesions did not develop on fruit pv. tomato in the period following anthesis and before the fruit reach 3 cm when flower buds were inoculated prior 'to anthesis. Susceptibility of green in diameter.
