Abstract: 
In order to investigate on the interaction between sucrose, honey and citric acid on postharvest life of cut Alstroemeria, a factorial experiment based on RCD carried out with 3 replications with 15 treatments. The treatments included of 5 levels of sugar (control, 2 and 4% sucrose, 2 and 4% honey) and citric acid in 3 levels (0, 200 and 400 mg L-1). Honey 2% in 400 mg L-1 citric acid in most traits had better than other treatments and maximum vase life (18. 7 days) achieved compared to control (9. 84 days). The lowest bacterial solution (3. 66 Log 10 CFU ml-1) and lowest MDA (11. 30 nmol g-1 FW) were observed in flowers treated with honey 2% in 400 mg L-1 citric acid. Control with 48. 72 nl l-1h-1 g-1 F. W. had maximum ethylene, and the 200 and 400 mg L-1 citric acid in without sugar, sucrose 4% in 400 mg L-1 citric acid and honey 4% in without citric acid had lowest ethylene production between treatments, respectively. The results showed that the use of honey (2%) and citric acid (400 mg L-1) reduced the bacterial solution, malondialdehyde and ethylene and delays wilting flowers. So cut flowers treated with these compounds is recommended to maintain vase life of cut alstroemeria.
