摘要: 【目的】 研究新疆厚皮甜瓜果实可溶性糖积累规律,为新疆厚皮甜瓜高糖品种培育及栽培管理奠定基础。【方法】 以可溶性糖含量具有明显差异的3份新疆厚皮甜瓜为材料,从授粉后10 d至果实完全成熟,采集心部和边部果肉,利用高效液相色谱仪测定可溶性糖含量。【结果】 材料HH、HL和LL成熟期心部果肉总糖含量依次为110.8、88.0和70.7 mg/g,边部果肉总糖含量依次为85.2、36.8和26.5 mg/g。除HH边部与HL心部、HL边部与LL边部果肉总糖间差异不显著外,其它两两之间均差异显著;HH心部果肉总糖及蔗糖快速积累的起始时间比HH边部及其它材料心部和边部果肉均至少提前了10 d;在果实发育过程中,果糖和葡萄糖含量相近,且整体波动相对较小,呈先增加后降低趋势,蔗糖和总糖变幅较大,蔗糖呈持续增加趋势,而总糖呈先增加后降低的趋势;总糖与蔗糖、葡萄糖、果糖、果实发育期均呈极显著线性正相关,其中与蔗糖相关系数最高,达0.96。【结论】 蔗糖含量及其积累起始时间是造成不同材料间及同一材料心部、边部总糖含量差异的主要因子;3份材料可溶性糖含量变化趋势基本一致,总糖、葡萄糖和果糖呈先增加后降低趋势,蔗糖呈持续增加趋势。

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.
