The impact of cultivar and production conditions on apple quality

Cultivar and production conditions influence the quality of apple fruits, and morphological, biochemical, and organoleptic attributes of apples can vary significantly even within the same cultivar. Numerous factors determine the commercial appearance of apples, as well as their nutritional and gustatory value. By comparing eight apple cultivars across different cultivation environments, this study highlights significant variations in tree growth, fruit yield, and quality. The findings reveal that super-intensive systems optimize land use and enhance yield efficiency but may impose physiological constraints that affect fruit size and biochemical composition. ‘Starkrimson’ and ‘Golden Delicious’ cultivars recorded the highest production in the intensive system, while ‘Granny Smith’ performed best in the super-intensive orchard. ‘Pinova’ demonstrated the highest yield efficiency, supporting its suitability for high-density plantations. Biochemical analyses confirmed substantial variability in dry matter, sugar content, and mineral composition, emphasizing the role of ecological and agronomic factors in shaping fruit quality. Sensory evaluations identified ‘Pinova’ and ‘Golden Delicious’ as the most appreciated varieties, reaffirming the importance of sweetness, texture, and aroma in consumer preferences. The study underscores the necessity of integrating genetic, environmental, and sensory analyses in apple research to optimize production and breeding strategies. These findings contribute to the advancement of orchard management practices, ensuring sustainable apple cultivation while maintaining high fruit quality for commercial markets.
