Abstract

A hot water dip at 50°C for 2 min was more effective than 1 KGy of gamma radiation in reducing Botrytis cinerea and Rhizopus stolonifer decay in inoculated light-red tomatoes. The combined hot water and radiation treatment acted synergistically on fungal development resulting in 1.7% and 10.0% infection by B. cinerea and R. stolonifer, respectively, after 5 days at 23°C compared with 67% and 100% infection in the non-treated controls. Under natural infection conditions, hot water dip followed by irradiation at 0.5 KGy totally eliminated decay by Alternaria alternata during 8 days at 23°C. All treatments caused more rapid fruit softening, with 20% soft fruit in the combined treated fruit compared with zero soft fruit in the non-treated control.
