瓜类水果因其味道甘甜、香气宜人而深受人们的喜爱。嫁接已广泛用于瓜类，以减轻非生物胁迫和控制土传疾病。但利用嫁接技术改良蔬菜果实品质的研究较少。在现代，水果质量尤其是感官质量特征对于消费者的眼睛来说至关重要。我们进行了液相色谱-质谱法和代谢组学分析，以检查嫁接到十种不同南瓜砧木上的甜瓜的感官果实品质。根据我们的研究结果，检测到478种代谢物，其中184种代谢物由脂质、氨基酸和有机氧化合物组成，在嫁接甜瓜果实中差异表达。代谢组学、理化和感官分析的结果解释了两种对比砧木甜瓜果实风味的差异。总之，与本研究中使用的其他砧木相比，天真1号砧木的果实表现出更好的感官特性和更高的可溶性糖含量[葡萄糖（19.87 mg/g）、果糖（19.68 mg/g）和蔗糖（169.45 mg/g）]。此外，与四庄12号嫁接瓜相比，天镇1号嫁接瓜果实中L-精氨酸、L-天冬酰胺、组氨酰组氨酸、乙酰DL-缬氨酸等引起苦味的氨基酸含量较低。这些果实品质特性使得天珍1号砧木适合玉娘瓜的商业化种植。
Melon fruits are popular because of sweet taste and pleasant aroma. Grafting has been extensively used for melons to alleviate abiotic stresses and control soil borne diseases. However, use of grafting for vegetable fruit quality improvement is less studies. In modern age fruit quality particularly sensory quality characteristics have key importance from consumer eye lens. We performed liquid chromatography-mass spectrometry and metabonomic analysis to examine sensory fruit quality of melon grafted onto ten different pumpkin rootstocks. Bases on the result of our study, 478 metabolites were detected and 184 metabolites consisting of lipids, amino acids and organic oxygen compounds were differentially expressed in grafted melon fruits. The results from metabolomic, physiochemical and sensory analysis explain the differences in melon fruit flavor from two con-trasting rootstocks. In conclusion the fruits from Tianzhen No. 1 rootstock exhibited better organoleptic char-acteristics and higher soluble sugars content [glucose (19.87 mg/g), fructose (19.68 mg/g) and sucrose (169.45 mg/g)] compared with other rootstocks used in this study. Moreover, the contents of bitterness causing amino acids such as L-arginine, L-asparagine, Histidinyl-histidine and Acetyl-DL-valine were found lower in Tianzhen No. 1-grafted melon fruits compared with Sizhuang No. 12-grafted melon fruits. These fruit quality character-istics made Tianzhen No. 1 rootstock suitable for commercial cultivation of Yuniang melon.
