摘　　要：以5年生阳光玫瑰(Shine Muscat)葡萄为试验材料,在末花期和末花后12 d用植物生长调节剂赤霉素(GA3)+噻苯隆(TDZ)+氯吡脲(CPPU)混合液处理果穗2次,并以清水处理为对照,在果实成熟期采用顶空固相微萃取结合气相色谱质谱联用(HS-SPME-GC-MS)测定了果实中香气物质种类与含量,研究植物生长调节剂对阳光玫瑰葡萄果实香气物质的影响,旨在为植物生长调节剂在阳光玫瑰葡萄生产上的应用提供参考依据。结果表明:对照共检测出74种香气物质,总含量为352.77μg/kg;植物生长调节剂处理共检测出61种香气物质,总含量为192.10μg/kg;对照确定了7种特征香气物质,而植物生长调节剂处理仅确定了3种;醛类和萜烯类是阳光玫瑰葡萄果实香气物质最主要的组成部分,其中芳樟醇对阳光玫瑰葡萄果实香味贡献最大,为主要的玫瑰香味呈香物质。总体上,使用植物生长调节剂GA_(3)+TDZ+CPPU混合液处理会减少阳光玫瑰葡萄果实香气物质种类和含量,并降低各特征香气物质活性值。Five-year-old‘Shine Muscat'grape was used as the test material.At the end of the flowering period and 12 days after the end of the flowering period,the mixture of plant growth regulator GA_3+TDZ+CPPU was used to treat the cluster twice,and treated with water as the control.Headspace-Solid Phase Microextraction and Gas Chromatography-Mass Spectrometry(HS-SPME-GC-MS)was employed to determine the types and contents of aroma components in the fruit at the fruit maturity stage,and the effects of plant growth regulators on the aroma components of‘Shine Muscat'grape fruit were studied.The aim was to provide reference for the application of plant growth regulators in the production of‘Shine Muscat'grape.The results showed that a total of 74 aroma components were detected in the control,with a total content of 352.77μg/kg.A total of 61 aroma components were detected in the plant growth regulator treatment,with a total content of 192.10μg/kg.The control identified 7 characteristic aroma components,while the plant growth regulator treatment only identified 3 characteristic aroma components.Aldehydes and terpenes are the most important components of aroma substances in‘Shine Muscat'grape fruit.Among them,linalool contributes the most to the aroma of‘Shine Muscat'grape fruit,which is the main rose aroma substance.In general,the use of plant growth regulator GA_(3)+TDZ+CPPU mixture reduced the type and content of aroma substances in‘Shine Muscat'grape fruit,and reduced the activity value of each characteristic aroma substance.
