| Abstract: | Effectiveness of γ-irradiation as a protective means against post-harvest decay in ‘Donner’ strawberries produced in Gumma Pref., Japan, was investigated. In case when strawberries were kept at 23°C, 10-% infection due to saprophytic fungi, such as Botrytis cinerea, Rhizopus and Penicillium, was found 3 days after zero-kiloroentgen (kR) irradiation, 4 days after 100-kR irradiation, and 5 to 6 days after 200-kR irradiation. For the purpose of wrap-film, ordinary cellophane was found to be more favorable than water-proof cellophane at room temperature.Main saprophytic fungus of ‘Donner’ berries was isolated and identified to be Botrytis cinerea Persoon. Lethal dose of B. cinerea was determined from its survival curve. |
