探讨天水地区大樱桃香气成分差异，为甜樱桃优良品种的香味遗传育种、香气合成代谢、分子生物学研究方面提供理论依据。以天水地区主栽的 7个大樱桃品种为试材，使用顶空固相微萃取气相色谱质谱联用技术( HS-SPME-GC-MS)鉴定果实中存在的香气物质，应用 TIC峰面积归一法测定了各成分的相对含量。结果表明， 7个大樱桃品种中共检出 77种香气物质，其中布鲁克斯有 24种、含香有 25种、美早有 16种、萨米脱有 26种、拉宾斯有 35种、斯坦勒有 14种、红灯有 12种。 7个大樱桃品种果实香气物质含量各有差异，其中红灯醇类物质含量最高，为 432.4g/kg；斯坦勒酯类物质含量最高，为 2.26 %；含香醛类物质含量最高，为 488.8 g/kg；布鲁克斯酮类物质含量最高，为 68.8 g/kg；其他类物质拉宾斯含量最高，为 255.8 g/kg。7个大樱桃共有的物质为苯甲醛，被认定为关键香气成分；特有香气物质拉宾斯 11种、布鲁克斯 10种、萨米脱 9种、含香 7种、斯坦勒 3种、美早 2种。

This study investigated the differences in aroma components of sweet cherry in the Tianshui area, aiming to providetheoretical basis for aroma-related genetic breeding, aroma biosynthesis metabolism, and molecular biology research of superior sweetcherry variety. Using 7 main cultivated sweet cherry varieties in Tianshui area as test materials, aroma compounds present in the fruitwere identified using headspace solid-phase microextraction combined with gas chromatography-mass spectrometry (HS-SPME-GC-MS), and the relative content of each component was determined using the TIC peak area normalization method. Results showed that a to.tal of 77 compounds were detected in the 7 sweet cherry varieties, including 24 in Brooks, 25 in Hanxiang, 16 in Meizao, 26 in Summit,35 in Lapins, 14 in Stella, and 12 in Hongdeng. The Aroma compounds content in the fruit of the 7 sweet cherry varieties varied. Hong.deng variety had the highest content of alcohol substances at 432.4 g/kg, Stella variety had the highest content of esters at 2.26%, Hanx.iang variety had the highest content of aldehydes at 488.8 g/kg, Brooks variety had the highest content of ketones at 68.8 g/kg, and Lapinsvariety had the highest content of other substances at 255.8 g/kg. The substances shared by the 7 sweet cherries were benzaldehyde,which was identified as key aroma component. Unique aroma compounds were also identified, including 11 in Lapins, 10 in Brooks, 9 inSummit,7inHanxiang, 3inStella,and 2 inMeizao.
