Abstract : Recently, radiation has been used as a fungicidal treatment in the post harvest technology of fruits. The effect of gamma irradiation at doses of 5 - 3000 Gy, on spore germination and mycelial growth of four fungi (Alternaria tenuissima, Botrytis cinerea, Penicillium expansum & Stemphylium botryosum) pathogenic to stored pears were studied. Inhibition of spore germination was found to be directly related to the strength of the radiation dose. B. cinerea and P. expansum were radiation sensitive, while A. tenuissima and S. botryosum were radiation resistant. Exposure of mycelial mat to different radiation doses showed that a dose level of 1000 and 3000 Gy could be considered sufficient for decontamination by the radiosensitive and radio-resistant species, respectively. Regardless of index of mycelial age, young mycelia were more resistant than mature mycelia. The lower doses of gamma radiation increased total proteins and total soluble sugar s of all the tested fungal species but did not effect lipid synthesis.
