chinois. 以不同类型的蓝莓（Blueberry）两个品种（蓝丰和粉蓝’为试材，分析了喷施不同浓度（0．1％、0．5％和1％）的蔗糖溶液对蓝莓果实发育期叶片和果实中可溶性糖含量、组成的影响，并进行了相关性分析。结果表明：在整个果实发育过程中（蓝丰：五月初至七月中旬；粉蓝：五月底至八月中旬），两品种叶片中可溶性糖总含量逐渐增加，但各个可溶性糖含量变化规律有所不同；两个品种果实成熟时期主要是积累葡萄糖和果糖为主，蔗糖含量很少，葡萄糖和果糖含量相当，并且随着果实的发育，各处理都可以不同程度的增加蓝莓果实的可溶性糖含量，其中，喷施0．5％的蔗糖溶液增加的最多；通过对各个处理叶片和果实可溶性糖含量的相关性分析可以看出，叶片和果实中可溶性糖含量显著相关。对叶片喷施0．5％的蔗糖浓度对增加蓝莓果实中的糖度提高最多。
Afficher plus [+] Moins [-]anglais. Two Blueberry varieties(Bluecrop’and f’owderblue’)were used as materials. Seasonal changes of solu- ble sugar contents in fruits and leaves and their relationship were studied, which were spraied different sucrose （0.1% ,0.5% and 1% ）. Result showed that two varieties of the total soluble sugar content in leaves gradually increased during the whole period of fruit development （Bluecrop： early May to mid ‘ July; Powderblue： the end of May to mid -August）, However, changes of soluble sugar content of each is different;The content of glucose and fructose were mainly accumulated in mellow fruit kept a high level, and sucrose content was at a low lever, the process can be different increased levels of soluble sugar content of blueberry fruit during the whole period of fruit development,of which 0.5% sucrose solution spraying increased the most; leaves and fruit soluble sugar content was significantly related 0.5% sucrose solution spraying increased the sugar content in blueberry fruit the most.
