Abstract:
‘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.
