比较了14个不同品种龙眼果实成熟期品质，以及在室温（25 ℃）和低温（4 ℃）条件下品质的变化和贮藏性的差异。结果表明：“储良”、“双孖木”、“赐合种”、“罗伞木”、“东壁”和“福眼”单果重>10 g；“东莞大果”、 “古山二号”、 “绿珠”和“水眼”单果重8~10 g；其余品种单果重<8 g。“储良”单果重最大，果形指数>1.05，可食率>70%，是较优质品种。综合常温和低温条件下不同品种在感官指标和营养品质上的变化差异，将龙眼分成三种类型：不耐贮藏品种、耐贮藏品种和中等耐贮藏品种。其中‘福眼’皮厚率<4%，果皮最薄，失重率最高，TSS含量和Vc含量较低，果皮褐变指数最高，果肉自溶指数较高，是不耐贮藏的品种之一。“石硖”果形较小，Vc含量和TSS含量较高，失重率较小，褐变指数最低，属于耐贮藏品种之一。

The quality of 14 varieties of longan fruits (‘Guangzao’, ‘Dongguan Daguo’, ‘Shixia’, ‘Luosanmu’, ‘Gushan No.2’, ‘Lvzhu’, ‘Shuiyan’, ‘Jidanben’, ‘Cihezhong’, ‘Fuyan’, ‘Shuangmamu’, ‘Dongbi’, ‘Chuliang’ and ‘Fengliduo’) at mature stage, and their storabilities under room temperature (25 ℃) and low temperature (4 ℃) conditions were studied. The results showed that 14 varieties of longan can be devided into big, middle and small fruits by its single fruit weight. ‘Chuliang’, ’Shuangmamu’, ‘Cihezhong’, ‘Luosanmu’, ‘Dongbi’ and ‘Fuyan’ belong to big fruits and the single fruit weight is more than 10 g; ‘Dongguan Daguo’, ‘Gushan No.2’, ‘Lvzhu’ and ‘Shuiyan’ belong to middle fruits and the single fruit weight is among 8~10 g; the other varieties belong to small fruits and the single fruit weight is less than 8 g. Among these varieties, ‘Chuliang’ has the largest single fruit weight, with a fruit shape index bigger than 1.05 and an edible rate more than 70%, showing a good fruit quality. The 14 varieties are classified into the high storability, the low storability and the middle storability based on their storabilities at normal and low temperatures. Among 14 varieties, ‘Fuyan’ is one of the varieties of the low storability. ‘Fuyan’ fruit has the thinnest pericarp thickness, lower contents of TSS and Vc in aril, and higher mass loss rate, pericarp browning index and aril breakdown index during storage. ‘Shixia’ is one of the varieties of the high storability. ‘Shixia’ fruit has the smaller fruit size, lower mass loss rate and pericarp browning index, and higher contents of TSS and Vc in aril during storage.
