摘　　要：【目的】研究不同时期对克瑞森无核葡萄进行主干环剥后,果实中可溶性糖含量和组分特性与差异,为环剥对果实可溶性糖的影响奠定理论基础。【方法】在4个不同时期,对克瑞森无核葡萄进行主干环剥,监测果实的生长发育情况,用高效液相色谱法测定其成熟期果实中可溶性糖组成成分和含量并进行相关性分析。【结果】5个试验处理中,第1次环剥处理的果实的果形指数最大,比对照处理大5.67%,单粒重也最大,达2.99 g。成熟期最早的是第3次环剥处理, 5个试验处理的果实的可溶性糖主要由果糖、葡萄糖和蔗糖组成,其中葡萄糖和果糖含量高,变化幅度大,蔗糖含量相对稳定,葡萄糖的含量略高于果糖。其中葡萄糖含量最高的是第2次环剥处理,极显著大于对照处理,比其高21.67%;果糖含量最高的是第3次环剥处理,极显著大于对照处理,比其高21.4%;蔗糖含量最高的是第4次环剥处理,比对照处理高29.65%;总糖含量最高的是第2次环剥处理。葡萄糖和果糖与可溶性总糖间存在极显著的正相关,葡萄糖与果糖之间呈极显著正相关,果糖与可溶性总糖间的相关性最大,略高于葡萄糖与可溶性总糖间的相关系数。蔗糖与可溶性总糖间的相关性最小,且无显著相关关系。【结论】主干环剥有利于克瑞森无核果实的生长和可溶性糖的积累,前期(坐果后到果实膨大期)进行环剥明显可以达到增产目的,后期(果实膨大期过后)环剥有利于果实提前成熟。【Objective】The project aims to contrast the differences and analyze the characteristics of soluble sugar content and components in different stage of Crimson seedless grape with trunk girdling in four different periods in the hope of laying a theoretical foundation for revealing the effect of girding on soluble sugar in fruits.【Method】The trunk girdling of Crimson seedless grape was carried out in four different periods to monitor the growth and development of the fruit.The soluble sugar components and content in the mature fruit were determined by high performance liquid chromatography and the correlation analysis was carried out,too.【Result】Among the five test treatments,the fruit shape index of the first girdling treatment was the largest,5.67%larger than that of the check treatment,and the single grain weight was also the largest,reaching 2.99 g.In terms of maturity,the third ring stripping treatment was the earliest.The soluble sugar of the fruit was mainly composed of fructose,glucose and sucrose in the five experimental treatments,among which the content of glucose and fructose was high,the amplitude of variation of which was large,the content of sucrose was relatively stable,and the content of glucose was slightly higher than that of fructose.The highest content of glucose was the second girdling treatment,which was significantly higher(21.67%higher)than that of the check treatment.The highest content of fructose was the third girdling treatment,which was significantly higher(21.4%higher)than the control treatment.The highest content of sucrose was the fourth girdling treatment,which was 29.65%higher than that of the check treatment;the highest total sugar content was the second ring stripping treatment.There was a significant positive correlation between glucose,fructose and soluble total sugar,and between glucose and fructose.The correlation between fructose and total soluble sugar was the largest;The analysis found that the correlation of fructose and soluble total sugar was the highest,whi
