摘  要:
香气作为果实品质的一个重要指标,近年来逐渐受到人们的关注。随着化学分析仪器和手段的迅速发展,特别是气相色谱-质谱联用技术的应用和分子生物学技术的广泛应用,香气研究在许多领域都取得了重大的突破。果实香气研究经历了香气组分分析、特征香气鉴定、香气生物合成途径分析及香气的遗传控制和改良等发展阶段。描述了果实香气的主要组成成分(醇类、酯类、醛类、酚类、萜类),对一些代表性水果的特征香气成分进行了归纳总结,重点介绍了与果实香气合成密切相关的脂肪酸途径、氨基酸途径,萜类合成途径以及关键酶的研究进展,展示了最近果实香气成分的遗传控制和转基因研究方面的最新成果,提出了开展桃果实香气性状遗传控制研究思路。

摘  要:
As an important trait of fruit quality,aroma has gained increasing attention in recent years.With the fast progress in plant molecular biology and the advances of analytical apparatus,especially the application of the GC-MS technology,new progress in aroma research has been made in several fields.Fruit aroma research has gone through the following steps:aroma composition analysis,detection of characteristic components,the biochemical pathway and the genetic control of aroma.In this review,we summarized firstly the composition of fruit aroma(alcohol,ester,aldehyde,benzene,terpene),the characteristic aroma compounds of several representative fruits.Then three pathways(fatty acid metabolism,amino acid metabolism,terpene synthesis metabolism)and the key enzymes involving the production of aroma were elucidated.In the end,we showed the recent achievements in the genetic and transgenic analysis of fruit aroma,and put forward some ideas in studying genetic control of peach aroma.
