Abstract
The cut flower business has been growing rapidly worldwide, with a positive and significant impact on the economies of many countries. Maintaining quality and extending the vase life of cut flowers are crucial aspects of the floral industry. Synthetic preservatives (silver nitrate, silver thiosulfate, nano-silver, hydroxy quinoline, thiabendazole, and aluminum compounds) have been commercially used in the vase to maintain the quality and longevity of cut flowers for a long time. However, these preservatives may persist in the environment, causing severe health hazards and environmental pollution, and are also expensive. Therefore, cut flower industries seek low-cost, eco-friendly, and safer alternatives. In this context, natural preservatives (NPs), including plant extracts (PEs) and essential oils (EOs), offer a promising and sustainable alternative to synthetic preservatives in the vase. This review highlights the potential NPs and their role in enhancing the quality and vase life of cut flowers. We discussed how these preservatives exert their beneficial effects, such as inhibiting microbial growth, reducing ethylene production, and enhancing water uptake, and also explored the potential issues associated with them. We conducted a structured literature review and summarized the most commonly used EOs and PEs, their optimal dosages, efficacy, and combinations, and concluded with future directions to enhance the vase life of cut flowers sustainably.
