【摘要】 为探究环剥后‘夏黑’葡萄果实发育代谢机制，利用生理指标测定和气相色谱-质谱（GC-MS）联用技术对其进行代谢分析。结果表明：环剥后果实中可溶性固形物、可溶性糖含量显著提升，可滴定酸含量显著下降。环剥后差异代谢物在半乳糖代谢、淀粉和蔗糖代谢、ABC转运蛋白、乙醛酸和二羧酸代谢通路中显著富集，蔗糖和酒石酸是参与上述通路的关键代谢物，其含量分别表现为增加和降低，促进果实成熟和品质提升。更多还原

【Abstract】 To investigate the metabolic mechanism of ’Summer Black’ grape fruit development after trunk girdling, physiological parameters and gas chromatography-mass spectrometry(GC-MS) were used to conduct metabolic analysis. It was found that the contents of TSS and SSC in fruits after trunk girdling were significantly increased, while the contents of TA were significantly decreased. Differential metabolites were significantly enriched in the pathways of galactose metabolism, starch and sucrose metabolism, ABC transporter, glyoxylic acid,and dicarboxylic acid metabolism. Sucrose and tartaric acid were the key metabolites involved in the above pathways, and their contents increased and decreased, respectively, thereby collectively promoting fruit ripening and improving fruit quality.更多还原
