“烟富6号”和“烟富7号”短枝富士果实品质评价分析

Fruit Quality Evaluation of Two Spur-type Fuji Apple Varieties"Yanfu 6"and"Yanfu 7"

短枝富士品种是富士苹果中一个非常重要的芽变类型,具有易成花、结果早等突出特点,本试验研究了套袋条件下“烟富6号”“烟富7号”2个短枝富士苹果果实品质、糖酸组分和香气物质的差异。结果表明,2个品种均为酯香型品种,“烟富7号”品种果实的平均单果质量、果形指数、果实硬度、琥珀酸、草酸、柠檬酸以及蔗糖和山梨醇含量均高于“烟富6号”;2个品种的主要香气成分存在差异,“烟富6号”主要香气成分为乙酸己酯和2-甲基丁酸己酯,“烟富7号”主要香气成分为2-甲基丁酸己酯和丙酸己酯;套袋果实摘袋后,“烟富6号”先条纹状着色再变为片红,而“烟富7号”为片状着色。

Spur-type Fuji apple variety,as one important bud mutation has the characteristics of early fruiting and compact tree shape.In this experiment,the difference of fruit quality,sugar and acid components and aroma components were researched on the 2 spur-type Fuji apple varieties"Yanfu 6"and"Yanfu 7"in the fruit bagging.The results showed that the contents of average fruit mass,fruit shape index,fruit hardness,succinic acid,oxalic acid,citric acid,sucrose and sorbitol from"Yanfu 7"were higher than those of"Yanfu 6".The main aroma components of"Yanfu 6"were Acetic acid,hexyl ester and Hexyl 2-methylbutyrate,and those of"Yanfu 7"were Hexyl 2-methylbutyrate and Hexyl propionate.After picking the bagging,the color of"Yanfu 6"was striped and then turned to flake red,while that of"Yanfu 7"was flake colored.
