Spiegel-Roy P. and Padova R. Radiosensitivity of Shamouti orange (Citrus sinensis) seeds and buds. Radiation Botany 13, 105-110, 1973.-Seeds, budwood and plants of the orange cv. Shamouti were irradiated with a 60Co gamma source. The LD50 for seeds was between 8 and 10 kR, with 12·5 kR being 90 per cent lethal. Peeled seed germinated earlier, but showed no differences in radiosensitivity. Some stimulation of germination rate and early growth with low doses was found, but the effect was inconsistent and in most cases temporary. Buds from shoots originating on plants irradiated with 4-8 kR, did not sprout as well as the control, when budded to rootstocks. Buds from shoots irradiated after being detached from the tree, had a LD50 below 5 kR, with few buds surviving the 7·5 kR dose. No appreciable differences in radiosensitivity between buds of nucellar and 'old clone' origin were noted. © 1973 Pergamon Press Ltd.
