In this research effect of Artemisia oil on vase lifeand postharvest quality of cut chrysanthemum (Dendranthemagrandiflorum) were investigated. The experiment were conducted based on randomized completely design with 4 levels of Artemisia oil (0, 10, 30 and 50%) and 3 replications. Analysis of variance showed thateffect of Artemisia oil on vase life, brix in final day (p≤0.05), protein content and chlorophyll a(p≤0.01) was significant. Results showed that 30% Artemisia oil with 10 days vase life, 32.76% protein content, 1.62 chlorophyll a and 3.16 °brix was the best treatment compared to other levels of Artemisia oil.
