摘　　要：为探究常温条件下ClO_(2)结合1-MCP处理对荔枝的保鲜效果,为荔枝的常温贮藏提供理论依据。以采摘后新鲜的无核荔枝为试材,分别进行ClO_(2)、1-MCP、ClO_(2)+1-MCP处理,并于(25±2)℃下贮藏,定期测定其好果率、可溶性固形物含量、褐变指数、色泽参数、细胞膜渗透率、多酚含量、抗氧化能力多项指标。结果表明:与对照相比,3种处理均能提高荔枝的好果率,有效抑制荔枝可溶性固形物含量的降低和褐变指数、相对电导率的升高,延缓多酚降解,保持果实较强的抗氧化能力。整体上看,以ClO_(2)+1-MCP处理的荔枝常温保鲜效果最佳。In the present study,the preservation effects of ClO_(2) combining 1-MCP treatments on seedless litchis at room temperature were researched,which would provide theoretical basis for room-temperature storage of litchis.Fresh-picked seedless litchis were used as materials and treated with ClO_(2),1-MCP and ClO_(2)+1-MCP under(25±2)℃storage respectively,then the healthy fruit rates,soluble solid contents,browning indices,color parameters,cell membrane permeabilities,polyphenols contents and antioxidant capacities of fruits were measured regularly.Results showed that these treatments could all improve the marketable fruit rates of litchis,and effectively control the reduction of soluble solid contents and the increase of browning indices and relative conductivities,delay the degradation of polyphenols,and keep the strong antioxidant capacities of fruits.Overall,ClO_(2)+1-MCP treatment exhibited better preservation effects on seedless litchis at room temperature.
