The Dynamics of Starch and Total Sugars during Fruit Development for Ionathan, Starkrimson and Golden Delicious Apple Varieties

Apples represent one of the most important elements in the human diet. The research carried out involved three apple varieties (Starkimson, Ionathan and Golden Delicious) harvested during development, which were analyzed in terms of physico-chemical profile. During fruit development, diameter and mass increased continuously for all the three apple varieties studied, acidity decreased and total soluble solids content increased significantly. The pH values of the apple pulp also increased confirming the results obtained for the acidity. The starch concentration was reduced in the early stages of fruit development in all three varieties of apple studied. Starch concentration significantly increased (p
