Abstract

The long apple cultivar is in increasing demand in the markets thanks to its unique shape, aroma, and its endemic and delicious taste. This study aimed to determine the physical and chemical changes throughout the fruit development, which indicates its optimum harvest time. Fruit samples were collected every two weeks from the last week of May to the middle of October. The fruit harvest time was evaluated depending on different quality note attributes including physical, mechanical, chemical, physicochemical, and pomological properties. The weight, fruit size, sphericity, color, soluble solids content, pH, firmness, elasticity, phenolic content (gallic acid and catechin), and organic acids (citric acid and ascorbic acid) were analyzed. Throughout the ripening period, fruit weight, fruit size, sphericity, and SSC gradually increased. There was a negative correlation between organic and phenolic contents and harvest dates. The optimum harvest time of Kagizman long apple was approximately 18 weeks after the full bloom.
