摘　　要：试验以三年生‘北陆’越橘品种为材料,在果实、叶片发育的不同时期进行取样,测定葡萄糖、果糖、蔗糖、山梨醇含量及蔗糖合成酶和转化酶活性的动态变化。结果表明,山梨醇是越橘叶片光合作用的主要产物;叶片中分解方向的酶远大于合成方向的酶,酸性转化酶活性一直较高;蔗糖含量与酸性转化酶活性呈显著负相关。越橘果实中糖分积累以葡萄糖和果糖为主,葡萄糖含量高于果糖;且酸性转化酶和蔗糖合成方向的酶是越橘果实糖分积累的关键酶。The experiment used three-year-old Blueberry varieties as materials and samples were taken at different stages of fruit and leaves development to determine the dynamic changes of glucose,fructose,sucrose,sorbitol,and sucrose synthase and invertase activities.The results showed that sorbitol is the main product of photosynthesis in blueberry leaves;the enzymes in the decomposition direction were much larger than those in the synthesis direction,and the acid invertase activity was always higher;the sucrose content and acid invertase activity were significantly negatively correlated.The sugar accumulation in blueberry fruit is mainly glucose and fructose,and the glucose content is higher than fructose;and acid invertase and enzymes in the direction of sucrose synthesis are the key enzymes for sugar accumulation in blueberry fruit.
