Abstract：Components and contents of soluble sugars and organic acids in mature fruit of watermelon germplasm were determined and analyzed by 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 and showed very significant positive correlation with total sugars,the value varied from 3.02-41.58 mg· g-1 and 0-46.03 mg· g-1 among germplasm respectively.The major organic acid was malic acid,which accounting 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.The content of soluble sugars and organic acids were highly different in different watermelon germplasm,and the variable coefficient of citric acid in Citrullus lanatus ssp.mucosospermus was up to 133％ while the variable coefficient of sucrose is 0.These results provided scientific basis for understanding the difference of fruit quality in different watermelon germplasm and a reference for evaluation germplasm resources and variety breeding in the future.
