Abstract:
The tuberose (Polianthes tuberosa L.) is an ornamental plant native to Mexico with flowers that are popular due to their delicate beauty and intense fragrance. However, as a plant resource, it has not been well studied or commercialized. If properly managed and/or exploited, this cut flower crop has the potential to further develop and expand the Mexican ornamental horticultural industry. At present, few studies have focused on increasing its relatively short shelf-life, which lasts about 7–10 day postharvest. As a result, this review focuses on basic aspects of the cut flower’s physiology, biochemistry, water relations, and postharvest floral opening. Also included are its response to cooling, the implementation of different packing strategies, the application of pulsing, preservative, and hydrating solutions, and the use of 1-methylcyclopropene as an inhibitor of ethylene action. A thorough analysis of all these technologies, their mode of action, and their influence on the physiological response of cut tuberose is essential for the improvement of postharvest management strategies. It is hoped that both handlers and distributors can benefit from this information and be successful in prolonging the shelf-life of this valuable ornamental resource.
