摘　　要：冷害是黄桃果实低温贮藏产生的一种生理性病害,本文选用1-甲基环丙烯(1-MCP)与乙烯吸附剂(EA)联合处理黄桃,研究1-MCP-EA和1-MCP对其果实冷害(CI)与糖代谢的影响。将黄桃在4℃下贮藏28 d,与对照和1-MCP相比,1-MCP-EA处理能够更好地维持果实硬度和可溶性固形物(soluble solid content,SSC)含量,减轻冷害褐变。黄桃果实糖含量与蔗糖代谢相关酶活研究表明,1-MCP单独处理和1-MCP-EA联合处理均能减少蔗糖含量的下降以及果糖与葡萄糖含量的上升,抑制酸性转化酶(AI)与中性转化酶(NI)活性的升高。1-MCP-EA处理可有效抑制黄桃果实的蔗糖合成酶(SS)活性上升和蔗糖单磷酸合成酶(SPS)活性下降。结论:1-MCP-EA处理抑制黄桃冷害效果最好,营养品质保持程度最佳。Chilling injury is a physiological disease of yellow peach fruit during low temperature storage.In this paper,yellow peach was treated by 1-methylcyclopropene(1-MCP)and ethylene adsorbent(EA),and the effects of 1-MCP-EA and 1-MCP on chilling injury(CI)and sugar metabolism were studied.Yellow peach was stored at 4℃for 28 days,compared with the control and 1-MCP,1-MCP-EA treatment could better maintain fruit hardness,soluble solid content(SSC)and reduce chilling injury browning.The results showed that 1-MCP-EA and 1-MCP treatment could reduce the decrease of sucrose content and the increase of fructose and glucose content,and inhibit the increase of acid invertase(AI)and neutral invertase(NI)activities.1-MCP-EA treatment could effectively inhibit the increase of sucrose synthase(SS)activity and the decrease of sucrose phosphate synthase(SPS)activity in yellow peach fruit.Therefore,1-MCP-EA treatment had better effect on inhibiting chilling injury and maintaining nutritional quality in yellow peach.
