Relationships were examined between environmental conditions mediated by packaging and handling and the deterioration of harvested Geraldton waxflower (Chamelaucium uncinatum) cv. Fortune Cookie. Disease severity plus flower and leaf drop caused by inoculation with Botrytis cinerea were reduced by lowering handling temperatures to 0, 5 or 5/20 deg C alternated daily, vs. 20 deg C. They were also reduced by inhibition of ethylene action with a silver thiosulfate pulse pretreatment. Additionally, treatments that enhanced water loss, such as packing dry, keeping forced air-cooling holes open and strategic placement of extra ventilation holes may also reduce disease severity and flower plus leaf fall. Inclusion of KMnO4-based Bloomfresh ethylene scrubbing sachets in packages did not reduce disease severity or lessen flower plus leaf fall. Thus, deterioration of waxflower packaged in commercial cartons can be minimized by keeping temperatures low, packing plant material dry, use of cartons with strat
egically placed ventilation holes and/or pretreatment with silver thiosulfate.
