Abstract : Purpose of the review: Irradiation is an effective quarantine treatment for global trade of fresh produce. The focus of this review is to examine the impact of various crop cultivars and maturity stages on the tolerance of fresh fruits to irradiation for the purposes of quarantine security. Main findings: Tolerance thresholds for irradiated fruit are lacking for a large number of modern cultivars. Cultivar differences in radiation sensitivity are most apparent for bananas, citrus, peaches and mangoes. Some of the variation attributed to cultivars may be maturity effects. For climacteric fruit, maturity stage at the time of treatment impacts the quality and shelf-life of irradiated product. Irradiation applied at the preclimacteric stage may delay ripening, but higher doses can injure less mature fruit. Overall, many fruit types tolerate doses below 500-600 Gy. Directions for future research: The major cultivars in current production should be evaluated at varying stages of maturity following irradiation at the range of doses (>1000 Gy) approved for quarantine treatment. Respiration and ethylene production rates should be monitored for individual varieties of climacteric fruits, before and after irradiation, to properly gauge the physiological maturity of the fruits and the impact of radiation on fruit ripening. Simulated shipping and ripening conditions following treatment at commercial radiation facilities would provide a clear assessment of the potential for successful export of irradiated fresh fruit.
