Currently, the cut flower market seems to be an export revenue in the world trade of the flower industry. The amount of exported cut flowers is impressive with increased production in various countries, especially in Korea. In the Fourth Industrial Revolution, automatic technologies are continuing to develop agricultural effective tools in the challenge of digital innovation. Thus, the low production costs set up in the field, greenhouse, or smart farm set up, and the short time of harvest must be considered within a few months. The postharvest quality of cut flowers presents freshness and long vase life, and the tools for postharvest handling are expected to optimize these. This review highlights the most important factors improving postharvest quality of cut flowers, the potential standard applicable techniques for commercial handling outlines of cut flower vase life, and recommendations for improving postharvest handling in the flower industry.
