  要:本研究采用离子色谱法对20个不同西瓜种质资源的成熟果实中的可溶性糖和有机酸组分及含量进行测定和分析。结果表明,西瓜果实中的可溶性糖主要是果糖和蔗糖,共占总糖含量的80.06%,与总糖呈极显著正相关,在不同种质间变化幅度较大,变幅分别为3.02-41.58 mg.g-1.FW0-46.03 mg.g-1.FW;有机酸主要是苹果酸,占总酸含量的83.88%,与总酸呈极显著正相关,变幅为1.66-5.38 mg.g-1.FW不同种质西瓜果实中的可溶性糖和有机酸存在明显差异,粘籽西瓜中蔗糖的变异系数最大,达到了133%,而蔗糖的变异系数最小为0。研究结果为了解西瓜种质间的果实品质差异提供科学依据,以及为今后开展不同品种资源的品质评价及品种选育提供参考。

Abstract: Components and contents of soluble sugars and organic acids in mature fruit of watermelon germplasm were determined and analyzed Ion Chromatography. The results indicated that the soluble sugars in watermelon were fructose and sucrose, which accounted for 80.06%of the value of total sugars, showed very significant positive correlation with total sugars, the value ranged from 3.02-41.58 mg.g-1.FW and 0-46.03 mg.g-1.FW, respectively; the major organic acid was malic acid, which accounted for 83.88%of the value of total acids, showed very significant positive correlation with total acids, the value ranged from 1.66-5.38 mg.g-1.FW; the soluble sugars and organic acids were highly different in different watermelon germplasm, and the coefficient of variation of citric acid in egusi seed watermelon was up to 133% while the coefficient of variation of sucrose is 0. These results provide scientific basis for understanding the difference of fruit quality in different watermelon germplasm, while providing a reference for evaluation germplasm resources and variety breeding in the future.
