果蔬采后品质变化生理生化机制及保鲜技术研究进展.doc

学年论文学生姓名朱鸿淼学号学院生命科学学院专业生物技术题目果蔬采后贮藏品质劣变生理生化机制研究现状指导教师宋虎卫2023年11月果蔬采后贮藏品质劣变生理生化机制研究现状摘要：果品蔬菜采后生理衰老是制约其贮藏保鲜的重要因素，同时由于人们生活质量的提高和外贸输出的增长等因素，探明果蔬采后生理变化规律对于开发果蔬、贮藏保鲜新技术、延长贮藏保鲜期尤为重要。该文综述了国内外关于果蔬采后呼吸生理、乙烯生理以及活性氧代谢等相关研究现状，以及冷害、高氧、多胺等因素对其的影响，在相关保鲜贮藏技术方面的应用，并展望了果蔬采后生理研究前景。关键词:果蔬；采后生理；现状；ResearchonthephysiologicalandbiochemicalmechanismofstoragequalitydeteriorationoffruitsandvegetablesAbstract:FruitsandvegetablesafterharvestphysiologysenescenceisanimportantfactorrestrictingitsPreservation,atthesametimeduetoincreasedoutputandforeigntradeincreasedqualityoflifereasons,afterprovenpostharvestphysiologyvariationforthedevelopmentoffruitsandvegetables,storageofnewtechnologytoextendthestorageandpreservationisofparticularlyimportance.Thispaperreviewstheresearchstatusrelatedrespiratoryphysiology,physiologicalandactiveoxygenmetabolismofethyleneandotherwellonpostharvest,andtheimpactofcoldinjury,hyperoxia,polyaminesandotherfactorsonthis,pplicationofthetechnicalaspectsrelatedtothepreservationstorageandtheprospectofpostharvestphysiologyresearchprospects.Keywords:Fruitsandvegetables;Postharvestphysiology；Statusquo.目录1，前言.................................................................................................................2，果蔬采后生理研究的发展过程...................................................................43，果蔬采后品质变化的生理生化机制的研究现状...............................33.1采后重要的生理变化........................................................................................43.1.1品质变化...........................................................................................................3.1.2呼吸作用..........................................................................................................3.1.3蒸腾作用..........................................................................................................3.1.4乙烯生成..........................................................................................................3.1.4活性氧代谢.....................................................................
