摘要: 为探究套袋对‘红花鹰嘴桃’果实品质的影响,采用气相色谱-串联质谱(gas chromatography-tandem mass spectrometry,GC-MS/MS)技术分析套袋组与未套袋组桃果实的代谢物。结果表明,在‘红花鹰嘴桃’果实中共鉴定出634 种代谢物,包括糖类11 种、游离脂肪酸33 种、挥发性物质590 种。其中显著差异代谢物107 个,包括上调物质59 个,下调物质48 个。与未套袋组相比,套袋组果实外观品质提升,山梨醇和油酸含量显著降低(P<0.05),挥发性物质种类更丰富,果实青香味减弱而花果甜香味增强。但套袋组果实的甜度值以及糖类物质、游离脂肪酸和挥发性物质总含量与未套袋组相比均无显著差异(P>0.05)。本研究可为桃果实套袋品质提升提供重要的理论依据。

Abstract: To investigate the effect of bagging on the fruit quality of ‘Honghuayingzui’ peach, gas chromatography-tandem mass spectrometry (GC-MS/MS) was used to analyze the metabolite profiles of bagged and unbagged peach fruits. The results showed a total of 634 metabolites were identified, including 11 sugars, 33 free fatty acids, and 590 volatile compounds. Among these, 107 significantly differential metabolites were identified, including 59 up-regulated substances and 48 down-regulated substances. Compared with the non-bagged group, the bagged fruit exhibited improved appearance quality and significantly reduced contents of sorbitol and oleic acid (P < 0.05). Additionally, the bagged fruit had a greater diversity of volatile compounds, with a weakened green aroma but enhanced floral, fruity and sweet aromas. However, no significant differences (P > 0.05) were observed in sweetness, total sugar, total free fatty acid, or total volatile compound contents. This study provides an important theoretical basis for improving the quality of bagged peach fruit.
