The vase life research of cut flowers is important to determine the vase life and to<br />

identify the best postharvest treatments for extending the vase life of cut flowers. This<br />

study investigated the effects of different concentrations of sucrose with combination<br />

of 8-hydroxyquinoline citrate (8-HQC) on the postharvest life of cut inflorescence of<br />

Antigonon leptopus (A. leptopus). These treatments were: Artificial Tap Water (ATW)<br />

as control; 8-HQC (100 mg/L); and combination of 1, 3, 5, 7 or 10% sucrose with 100<br />

mg/L 8-HQC. The effectiveness of the treatments was evaluated based on the relative<br />

fresh weight (RFW), vase solution uptake (VSU), pH, flower drop, vase life, colour and<br />

relative water content (RWC). Sucrose at 7% plus 8-HQC was significantly (P
