In this research effect of Artemisia oil was studied on postharwest longevity and quality of cut chrysanthemum cv. White flowers. Experiment carried out based on completely randomized desingn with Artemisia oil treatment at 4 levels (0, 10, 30 and 50%) in 3 replications. Analysis of variance showed that all of treatments had significant effect on measured traits (p≤0.05). Mean comparison showed that 30% Artemisia oil had the highest vase life, flower diameter and solution uptake with 10 days, 63.11mm and 1.09 ml g-1 F.W. respectively.
