摘　　要：硫化氢(H_(2)S)被认为是继一氧化氮(NO)和一氧化碳(CO)之后的第3种气体信号分子,近年来,研究证明H_(2)S在果蔬成熟衰老和抗病应答中具有重要的调控作用。结合最新的研究成果和课题组的研究工作,总结了H_(2)S在果蔬贮藏保鲜上的应用,以及从呼吸与能量代谢、乙烯调控、活性氧代谢、细胞壁降解、信号分子互作以及蛋白质翻译后修饰等方面概述了其可能的作用机制,并展望了H_(2)S在调控果蔬成熟衰老机制上的研究方向,为H_(2)S在果蔬贮藏保鲜上的应用提供理论依据。In recent years,hydrogen sulfide(H_(2)S),as an emerging endogenous gas signal molecule after nitric oxide(NO)and carbon monoxide(CO),has attracted more and more attention of researchers.In people’s traditional concept,H_(2)S is a colorless,highly corrosive gas with the smell of rotten eggs.However,researchers found that low concentrations of H_(2)S have a positive effect in cells,studies have shown that H_(2)S has the functions of inducing seed germination,promoting the growth and development of roots,stems,leaves and other organs,and enhancing resistance to biotic and abiotic stresses.In recent years,there have been many researches on the preservation and disease resistance of fruits and vegetables,which started with Hu’s research on strawberries in 2012,and then applied to various fruits and vegetables,and attracted wide attention from scholars in postharvest physiology of fruits and vegetables.As a signal molecule,the application concentration of exogenous H_(2)S is very low,so the treated fruit and vegetable products are safe.Some studies have shown that the exogenous H_(2)S treatment plays a positive role in the preservation of postharvest fruits and vegetables like kiwifruit,mulberry,banana,sweet cherry,hawthorn fruit,strawberry,litchi,broccoli,daylily flower,pak choy,sweet potato,pear,lotus root,apple and so on.During postharvest storage,fruits and vegetables will be affected by fruit softening,decay,and pathogen infection,which will lead to the decline of fruit quality and shortening of shelf life.The latest research showed that H_(2)S treatment could significantly delay fruit ripening and senescence.The quality of postharvest fruits and vegetables is reflected by color,firmness,soluble solid content(SSC),titratable acid(TA)and vitamin C(Vc)content.Some studies have shown that exogenous H_(2)S treatment could maintain the SSC,Vc and chlorophyll content,and inhibit the decrease of firmness.From the perspective of postharvest physiology,the researchers elaborated the role of H_(2)S in the process of fru
