Citrus fruit rind exhibits a 'curing' response when it is damaged which can be affected by the protein synthesis inhibitor cycloheximide and the fungicide potassium phosphonate. If the curing process can occur fast enough it can prevent the development of decay caused by the moulds Penicillium digitatum and P. italicum. Previous research has shown that holding fruit at 35 deg C and humidities greater than 75% for 2 to 3 days enhances this biochemical process, resulting in the formation of lignin and antifungal coumarin compounds. This treatment can prematurely age and soften the fruit. Curing at lower temperatures was enhanced by the use of the non-toxic compound potassium phosphonate, which increased the rate of curing and prevented mould development in inoculated oranges. The response was most noticeable at 15 deg C, while only slightly detectable at 35 deg C when compared to the control. The compound itself had no effect on the moulds in vitro.
