Abstract: Hydrogen sulfide, as a gas signal molecule in plants, regulates the metabolism of plants and affects the physiological activities and nutritional quality of postharvest fruits and vegetables during storage. Hydrogen sulfide participates in the regulation of ripening and senescence of fruits and vegetables, stimulates the expression of defense genes, induces the formation of disease damage response and resistance of plants, delays their postharvest senescence and prolongs shelf life. This paper summarized the research progress of hydrogen sulfide in the storage and preservation of postharvest fruits and vegetables at home and abroad. From the perspective of postharvest physiology, the role of hydrogen sulfide was expounded in the metabolism of fruits and vegetables. six aspects of sensory quality, energy metabolism, respiratory intensity, ethylene generation, browning and disease were discussesed in order to study the application of hydrogen sulfide in the preservation of fruits and vegetables in the future for reference.
