The duration of the half‐embryo test used for identification of gamma‐irradiated grapefruit was shortened by increasing germination temperature to 35°C. Maximum shooting percentages were reached within 3 days. Gibberellin application reduced the required incubation time to 2 days. Half‐embryos extracted from irradiated orange and lemon gave similar results to those of grapefruit. This half‐embryo test is proposed as an identification method for irradiated citrus. Assessment can be made after 3 to 4 days when shooting percentage is greater than 50%.
