In order to study the effect of external ethylene on postharvest display and activity of some senescence-related enzymes in potted miniature roses, this experiment was carried out in a completely randomized design, using three treatment levels with three replications. In glass chambers, potted miniature rose plants were exposed to ethylene concentrations of 0, 5 and 10 μL L-1 for 12 h. The results of study showed that the application of ethylene affected morphological and physiological properties and activity of antioxidant enzymes, as well as laccase enzyme in treated plants. Stress of ethylene in miniature roses caused to increase the percentage of leaf abscission and laccase enzyme activity. Studying defensive mechanism by measuring antioxidant enzymes showed that after using stress of ethylene activity of peroxidase enzyme was gradually decreased. Ethylene concentration of 10..
