摘　　要：【目的】研究不同矮化中间砧(M7、JM7、SCI、SH1、SH6、SH38、M26、T337)对嘎啦苹果果实品质的影响,为甘肃陇东地区生产高质量嘎啦苹果提供理论依据.【方法】测定8种矮化中间砧嘎啦果实的单果质量、果形指数、果实色泽、果实硬度、可溶性固形物、可滴定酸和香气成分,对果实品质指标进行综合分析.【结果】与对照相比,M7单果质量增加9.22%;SCI单果质量增加7.13%,果皮蓝黄色度增加22.98%,可滴定酸含量增加了0.04%;SH6果实硬度增加34.26%、可滴定酸含量增加了0.04%;SH1果皮蓝黄色度增加17.79%,果皮红绿色度增加20.98%;M26可溶性糖含量高了1.59%,香气总含量增加60.99%,酯类物质总含量增加70.50%,特征香气种类最多;SH38醛类物质总含量最高;M26、JM7、T337、SCI、SH6、SH38各含一种独特香气.【结论】嘎啦/M26、JM7/新疆野苹果这2个砧穗组合果实品质综合表现优于其它组合,对提高果实品质有益.【Objective】To study the effects of different dwarfing interstocks(M7,JM7,SCI,SH1,SH6,SH38,M26,T337)on the fruit quality of Gala apple,and to provides a theoretical basis for high-quality Gala apple production in Longdong of Gansu.【Method】The fruit quality indicators including individual fruit weight,fruit shape index,fruit color,fruit hardness,soluble solids,titratable acid and aroma components of Gala fruits grown from 8 dwarfing interstocks were measured and comprehensively analyzed.【Result】Compared with the control,the single fruit weight in M7 and SCI groups increased by 9.22%and 7.13%respectively;The peel blue-yellowness and titratable acid content in SCI group increased by 22.98%and 0.04%;The fruit hardness and titratable acid content in SH6 group increased by 34.26%,and 0.04%;The peel blue-yellowness and peel red-green color in SH1 group increased by 17.79%and 20.98%;The soluble sugar,total aroma and total ester contents of fruits in M26 group increased by 1.59%,60.99%and 70.50%respectively.Fruits in M26 group contained most types of characteristic aroma,and those in SH38 group showed the highest content of total aldehydes.Fruits in M26,JM7,T337,SCI,SH6 and SH38 groups contained a unique aroma.【Conclusion】In terms of general fruit quality,M26 and JM7 are better.
