Abstract
Blue mold caused by Penicillium expansum causes most of the losses during the storage period in the world. In this study, the inhibition effect of different doses of gamma radiation on spore germination and mycelial growth of Penicillium expansum was investigated. As a result, the Penicillium expansum was recovered from infected apple fruits. In order to evaluate the gamma radiation effect on the spore germination, spore suspension (104 spore/ml) exposed to 0, 100, 300 and 600 grey, using Co-60 gamma cell with a dose rate of 0.2 Gy/Sec. Also, a disk of mycelium (0.5 cm2) was removed from the edge of a three-days colony and transferred to PDA plates and irradiated to 0, 1500, 2000, 2500, 3000 and 3500 Gy. The results showed that, the irradiation has completely inhibited the spore germination at 600Gy. While, a dose of 3000Gy completely inhibited the mycelial growth of Penicillium expansum.
