| 摘 要： | 研究1-甲基环丙烯(1-MCP)处理对采后‘中青’台湾青枣果实贮藏品质与烟酰胺腺嘌呤二核苷酸激酶(NADK)活性、烟酰胺腺嘌呤二核苷酸(NAD)、烟酰胺腺嘌呤二核苷酸磷酸(NADP)、还原型烟酰胺腺嘌呤二核苷酸(NADH)、还原型烟酰胺腺嘌呤二核苷酸磷酸(NADPH)、能量物质三磷酸腺苷(ATP)、二磷酸腺苷(ADP)、一磷酸腺苷(AMP)]及能荷(EC)的关系。采后台湾青枣果实用1.8μL/L的1-MCP处理12 h后在(15±1)℃下贮藏,定期测定能量物质、NAD、NADP、NADH和NADPH含量、NADK活性及细胞膜透性,并在贮藏前后测定果实品质指标和腐烂率。结果表明:1-MCP处理保持‘中青’台湾青枣果实较高的ATP、NADP、NADPH含量,NADK活性和能荷值,较低的NAD和NADH含量,延缓贮藏期间细胞膜透性的增加;保持较高的果实硬度、可溶性固形物(TSS)、有机酸(TA)和维生素C含量,延缓果皮叶绿素含量下降,降低腐烂率。据此认为,1-MCP处理延缓采后台湾青枣果实衰老降低腐烂率可能与细胞保持较高的能荷水平有关。

| Abstract: | The effects of 1-methylcyclopropene (1-MCP) treatment on the storage quality of the harvested Ziziphus mauritiana Lamk.cv.Zhongqing fruit were investigated,with regard to its relationship with the activity of nicotinamide adenine dinucleotide kinase (NADK) activity,contents of nicotinamide adenine dinucleotide (NAD),nicotinamide adenine diuncleotide hydrogen (NADH),nicotinamide adenine dinucleotide phosphate (NADP) and nicotinamide adenine diuncleotide phosphate hydrogen (NADPH),contents of adenosine triphosphate (ATP),adenosine diphosphate (ADP)and adenosine monophosphate (AMP),and energy charge (EC).The harvested fruits were treated with 1.8 μL/L 1-MCP for 12 h then stored at (15±1)℃.The cellular membrane permeability,contents of ATP,ADP and AMP,NADK activity and contents of NAD,NADH,NADP,NADPH were determined regularly during the storage,while fruit quality was evaluated on the first and the last day of storage.The results showed that 1-MCP treatment could maintain higher activity of NADK,lower the content of NAD and NADH,increase the content of NADP and NADPH,delay the decrease of ATP content and energy charge,and retard the increase of cellular membrane permeability during storage;In addition,it could also keep higher firmness,contents of vitamin C,total soluble solids (TSS) and titratable acid (TA) in fruits,retard the decrease of chlorophyll content in pericarp and decrease fruit decay.Therefore,it could be concluded that 1-MCP treatment could maintaine the quality and delay the senescence of harvested Ziziphus mauritiana fruit due to higher retained cellular energy charge. |
