| Abstract: | 【Objective】 To study the rule of soluble sugar accumulation in fruit of muskmelon, and lay a foundation for cultivation management and breeding high-sugar varieties of muskmelon.【Methods】 Three Xinjiang thick-skinned melons with significant difference in soluble sugar content were used as test materials. From 10 days after pollination until the fruit was completely ripe, the heart and edge flesh was collected, and the soluble sugar content was determined by HPLC. 【Results】 In the maturity stage of HH, HL and LL,the total sugar contents of the heart flesh were 110.8, 88.0 and 70.7 mg/g, and the total sugar contents of the edge flesh were 85.2, 36.8 and 26.5 mg/g, respectively. Beyond that the total sugar contents between the edge flesh of HH and the heart flesh of HL, and the total sugar content between the edge flesh of HL and LL were not significantly different, respectively, the total sugar contents in the flesh of the three materials were all significantly different between each other. The starting time of rapid accumulation of total sugar and sucrose in HH heart flesh was at least 10 days earlier than that in HH edge flesh and other materials. In the process of fruit development, the contents of fructose and glucose were similar, and the overall fluctuation was relatively small, showing a trend of first increasing and then decreasing. The increase amplitude of sucrose and total sugar was large, while sucrose showed a trend of continuous increasing, while total sugar showed a trend of first increasing and then decreasing. There was a significant positive linear correlation between total sugar and sucrose, glucose, fructose and fruit development period, and the correlation coefficient with sucrose was the highest, up to 0.96.【Conclusion】 Sucrose content and the starting time of sucrose accumulation were the main factors that caused the difference of total sugar content in the heart and the edge of different materials and the same material. The change tendency of soluble sugar content of the three materials was basically the same, total sugar, glucose and fructose increased first and then decreased, while sucrose increased continuously. |
