The response of habituated embryogenic ovular callus of the "Shamouti" orange, Citrus sinensis, to gamma irradiation was studied. Stimulation of embryogenesis was observed when only callus, but not when the medium, was irradiated. Age of callus prior to subculture modified the response to irradiation as regards optimal dose for embryogenesis and radiosensitivity. Radiation intensities also modified callus response to radiation dose. Addition of unirradiated IAA to irradiated callus cultures increased embryo formation and furthered development of embryos into plantlets, with some combinations of radiation dose and IAA concentration. Addition of IAA also decreased radiosensitivity at high doses (32 kR). © 1977.
