Strigolactone (SL) is a signal factor that plays a vital role in plants. The application of SL for the storability of horticultural products has recently received attention. In this experiment, fresh-cut apples were treated with SL at diverse concentrations and stored at 4 °C for 10 days, and the changes in quality characteristics, antioxidant system, hydrogen sulfide metabolism, and nitric oxide metabolism were determined. Compared with other treatments, the results showed that SL treatment at 0.50 µmol L−1 had excellent effects on maintaining fruit surface color, weight, firmness, reduced respiration rate, soluble solids content, and electrolyte leakage. SL treatment increased antioxidant enzyme activities, reduced reactive oxygen species (ROS) accumulation, altered the nitric oxide synthase (NOS)-like pathway to promote endogenous NO production in the fruit, and facilitated the L-cysteine-catalyzed process to increase the endogenous hydrogen sulfide (H2S) content. In addition, SL treatment affected the mRNA transcription levels of several genes related to the antioxidant system, H2S metabolism, and NO synthesis, including MdSOD, MdCAT, MdPOD, and MdSAT. Taken together, the results indicated that 0.50 µmol L−1 SL treatment improves the endogenous synthesis of NO and H2S, enhances the antioxidative system, and maintains the quality of fresh-cut apples during their shelf life. Therefore, the present study opens up the possibility of using the exogenous application of strigolactone in the fresh-cut processing industry.

The increasing global population has heightened the demand for food, leading to escalated food production and, consequently, the generation of significant food waste. Factors such as rapid ripening, susceptibility to physiological disorders, and vulnerability to microbial attacks have been implicated as contributing to the accelerated senescence associated with food waste generation. Fruits and vegetables, characterized by their high perishability, account for approximately half of all food waste produced, rendering them a major area of concern. Various postharvest technologies have thus been employed, including the application of phytohormone treatments, to safeguard and extend the storability of highly perishable food products. This review, therefore, explores the physicochemical properties and biological aspects of phytohormones that render them suitable for food preservation. Furthermore, this review examines the effects of externally applied phytohormones on the postharvest physiology and quality attributes of fresh produce. Finally, the review investigates the mechanisms by which exogenous phytohormones preserve food quality and discusses the associated limitations and safety considerations related to the use of these compounds in food applications.
