基于代谢组揭示雪兔和妙香7号草莓果实香气物质的差异
Aroma compounds differences in strawberry fruits of Snow Rabbit and Miaoxiang No.7 revealed at metabolome level
摘要
Abstract
To clarify the differences in aroma compounds between white strawberry Snow Rabbit and red strawberry Miaoxiang No.7,the basic fruit quality and aroma compounds of the two varieties at the maturity stage were determined in this study.Basic qualities including single fruit weight,anthocyanin content,soluble solids content,and total phenolic con-tent were measured.Gas chromatography-mass spectrometry(GC-MS)was employed to detect volatile compounds in the fruits of the two strawberry varieties.The results showed that the fruit shape index of Miaoxiang No.7 was 1.41,the fruit was long conical in shape,while the fruit shape index of Snow Rabbit was 1.15,and the fruit was short conical in shape.The total phenolic content and anthocyanin content of Mi-aoxiang No.7 were 4.10 mg/g and 1.21 mg/g,respective-ly,both were significantly higher than those of Snow Rab-bit.A total of 471 metabolites in 15 categories were detec-ted in the two strawberry cultivars,of which 117 were up-regulated,24 were down-regulated,and 96 were differen-tially expressed metabolites,accounting for 20.38％ of the total metabolites.The eight differential metabolites with high quantities were alcohols,aldehydes,acids,terpenoids,hydro-carbons,ketones,heterocyclic compounds,and esters.These compounds were mainly enriched in the biosynthetic pathway of terpenoids.The main volatile compounds in Snow Rabbit strawberry fruit were esters,while those in Miaoxiang No.7 fruit were terpenoids.There were 20 characteristic aroma compounds in Snow Rabbit strawberry,with a herbaceous aroma type,and there were 22 characteristic aroma compounds in Miaoxiang No.7 strawberry,with a fruity aroma type.关键词
