Effect of apple position on the tree on maturity and quality

Abstract
A study was made on the effect of the position of the apple on the tree, its size and colour on maturation and quality at the post-harvest ripe stage. Position influenced the rate of maturation. Fruits at the bottom of the tree matured earlier than those at the middle and top. There was also a variation in maturation rate between full coloured and less coloured, interior and exterior fruits, and small and large ones on the same bunch and on separate stalks. Post-harvest ripened bottom apples had a poor colour but good eating quality whereas top fruits had a better colour and poorer aroma and taste. For better storage and organoleptic quality it is desirable to harvest apples from the bottom half of the tree earlier than from the top with a gap of 7–10 days between harvests.
