摘　　要：以陕西省千阳地区主栽苹果品种"金冠""乔纳金""富士"和"澳洲青苹"为试材,测定了各品种成熟过程中硬度、可溶性固形物含量、可滴定酸含量和淀粉指数,分析了各采收期苹果果实横切面淀粉染色程度,制作了4个苹果品种成熟期的碘-淀粉染色图谱,以期为陕西省千阳地区苹果采收期的判断提供参考依据。结果表明:苹果成熟过程中,4个苹果品种的淀粉指数均与果实硬度和可滴定酸含量呈显著负相关,与可溶性固形物含量和着色率呈显著正相关。碘-淀粉染色图谱可以客观反映苹果成熟度。‘Golden delicious＇ ‘Jonakin＇‘Fuji＇and‘Granny Smith＇apples were used as test materials.The changes of firmness,soluble solids content,titratable acid content and starch index were analyzed,the degree of starch staining in the cross section of apple fruit at different harvest stages were measured,and meanwhile,the iodine-starch staining patterns were built for four apple cultivars in order to supply reference for apple harvest in Qianyan of Shaanxi.The results indicated that the starch index showed a significantly negative correlation with the fruit firmness and titratable acid content in the four apple cultivars during ripening process,while a positive correlation was observed between the starch index and the content of soluble solids,coloring rate.Taken together,it suggested that the starch index could reflect apple maturity objectively and the iodine-starch staining pattern built could provide a reference for the apple production in Qianyang,Shaanxi Province.
