Summary

Penicillium hirsutum revealed a longer lag phase at 0 deg C and below, and its growth was reduced as the temperature was lowered. At -4 deg C, the fungus showed slight lengthening of the hyphae only after 19 weeks. Sporulation and germination of conidia were also delayed by low temperatures, and at -4 deg C there was no production or germination. Even at -2 deg C, P. hirsutum colonised all of the cloves after 7 weeks, while at -4 deg C they were all still healthy after 16 weeks. No freezing injury was encountered at temperatures lower than 0 deg C. A storage temperature of -4 deg C is advisable for the prevention of blue mould disease.
