An effective postharvest protocol for Acacia branches cut in bud is described. Branches of A. retinodes were cut at the yellow bud stage. Yellow buds were opened with a 16 h pulse at 10, 20 or 30 deg C with solution containing 0.01% Agral (wetting agent), aluminium sulfate and 1-2% sucrose. The addition of Agral to bud opening solutions at 10 or 20 deg C significantly enhanced the number of buds that opened as well as improving flower vase life. Agral and aluminium sulfate pulsing at 10 or 20 deg C was significantly more effective at opening buds than pulsing with sucrose solutions at 30 deg C, currently in use commercially. Branches transported at 20 deg C for 2.5 days with stems immersed in 5% sucrose + 50 mg chlorine/litre lasted longer than those transported dry in plastic sleeves in fibreboard boxes, but dry transported branches effectively rehydrated after 2.5 days of simulated transport at 20 deg C. Those branches transported dry required a 16 h posttransport pulse containing sucrose, or

a vase solution containing 1% sucrose, to maximize vase life, while branches transported in sucrose solution did not require a further supply of sucrose. Pulsing with 0.01% Agral was vital to ensure Acacia flowers withstood transport, whether shipped in solution, or tightly packed in plastic sleeves in flower boxes.
