Assessment of vase life and postharvest quality of cut rose (Rosa hybrida cv. Angelina) flowers by application of cumin (Cuminum cyminum L.) essential oil and 8-hydroxyquinoline sulfate

Abstract

Natural preservatives such as herbal essential oils have potential ability for extending postharvest vase life of cut flowers. In this study, application effect of cumin (Cuminum cyminum L.) essential oil and 8-hydroxyquinoline sulfate on vase life and postharvest quality of cut rose (Rosa hybrida cv. Angelina) flowers were investigated. A factorial experiment with three levels of each in different time after harvesting was conducted. Results showed that usage of different level of cumin essential oil and hydroxyquinoline sulfate had significant effects on rose attributes at the level of 0.05. The results showed that the interaction effect of cumin essential oil and hydroxyquinoline sulfate in measuring time was significant (P<0.05) on all of parameters except for anthocyanin content in rose petals in a way that the highest amount for measured traits was obtained with treatment of 150 mg L-¹ cumin essential oil and 400 mg L-¹ 8-hydroxyquinoline sulfate.
