Postharvest characteristic of Backhousia myritifoliaBackhousia myritifolia id a canopy rainforest species found along the eastcoast of Australia. The inflorescences are comprised of umbles containing six small (approximately 20-30 mm diameter)white flowers protruding from auxiliary nodes in the upper or terminal shoots. Recently, the cut stems of-1 have generated strong demand from florists in Japan, but there are frequent reports of poor quality. This paper investigates the effects of storage temperature on the vase life of B. myritifolia flower and foliage inflorescence respiration at 0°C was 4.5 mol kg-1h-1 and cut stems had respiratory Q10 of 2.3 between 0 and 10 °C for one week. However, no correlation was found between chlorophyll fluorescence parameters and symptoms of chilling injury. At storage temperatures of 5 and 10°C, desiccation was the primary cause of vase life termination. A postharvest anti-transpirant was applied to inhibit water loss but did not prevent desiccation. Storage at 15 °C caused flower and leaf abscission. The postharvest biology of B. myritifolia will continue to be investigated to further understand postharvest abscission, desiccation and blackening.
