The effects of different levels of naphthalene acetic acid were investigated on vase life and postharvest quality of cut Alestroemeria flowers in Islamic Azad University, Rasht Branch (Iran). Experiment carried out based on completely randomized design with naphthalene acetic acid (NAA) at 3 levels (0, 10 and 20 mg L-1) in 3 relplications. Analysis of variance showed that effect of NAA on the number of open florets, vase life, dry matter percentage and chlorophyll a (chl a) was significant (p≤0/05). Results demonstrated that maximum vase life, dry matter and number of open florets was achieved by 10 mg L-1 NAA with 9.85 days, 17.07% and 4.67 respectively. Highest chlorophpll a content was obtained by 20 mg L-1 NAA(3/02 μg /ml).
