Jonathan apples were irradiated with /sup 60/Co gamma rays, in doses of 0 (control), 2.5, 5, 7.5, 10, 50, 100 krad (dose rate: 20 krad/hr), and 50krad (dose rate: 100 krad/hr), and stored at 0 deg C in three controlled atmosphere rooms (oxygen 3 to 5%, carbon dioxide below 0.5%; oxygen 21%, carbon dioxide 2 to 2.5%; oxygen 3 to 5%, carbon dioxide 2 to 2.5%) and in a common refrigerated room for 4.5 months. Irradiation of apples with doses of 10 krsd or more seemed to lower slightly their qualities and the same tendency was obseved in CA apples. Generally, the effects of CA storage, especially in 3 to 5% O/sub 2/ and 2 to 2.5% CO/sub 2/, on the qualities of apples, i.e., respiration, organoleptic properties, changes in weight, surface color, were stronger than the irradiation effect. However, it seems to be true that the treatment with doses of about 5 krad is not at all inferior to the other treatment. So, as the pretreatment of CA storage of apples the irradiation dose of about 5 krad may be recommended. (auth)
