以采自甘肃紫轩葡萄酒业葡萄园的酿酒葡萄赤霞珠为试验材料，对果实中葡萄糖、果糖、蔗糖含量及糖代谢相关酶活性进行测定。结果表明，随着赤霞珠葡萄果实的生长，蔗糖、葡萄糖、果糖含量显著上升。不同生长发育阶段，赤霞珠果实中酸性转化酶、中性转化酶、蔗糖合成酶、蔗糖磷酸合成酶活力不同。相关性分析表明，整个发育期的葡萄糖、果糖、蔗糖与酸性转化酶活性存在显著正相关，R值分别为0.789、0.726、0.719；葡萄糖、果糖、蔗糖与中性转化酶活性、蔗糖磷酸合成酶、蔗糖合成酶活性均表现为极显著正相关。

Cabernet sauvignon was selected from the vineyard of Gansu Zixuan Wine Industry as the experimental material， the contents of glucose， fructose， sucrose and the activities of enzymes related to sugar metabolism in fruits were determined. The results showed that the content of sucrose， glucose and fructose increased significantly with the growth of Cabernet sauvignon grapes. The activities of acid invertase， neutral invertase， sucrose synthase and sucrose phosphate synthase were different in Cabernet sauvignon fruits at different growth and development stages. Correlation analysis showed that glucose， fructose， sucrose and activity of acidic invertase activity in the whole development period were significantly positively correlated， R values of 0.789， 0.726 and 0.719， respectively. The activities of neutral invertase， sucrose phosphate synthase and sucrose synthase were significantly positively correlated with glucose， fructose and sucrose.
