Relationship Between Fruit Quality, Storability and Mineral Composition of Apples

The analyses of mineral composition of 22 apple cultivars showed that the cultivars containing more cali-um and potassium and less copper and maganese have good flesh texture, high storability and an flavourous . Calium and potassium play an important role in raising flesh firmness and crispness, retarding the fruit softening and weightless process and keeping good flesh texture. The cultivars with crisp flesh have little copper and the cultivars with tenacious flesh contain much more copper. It seem that copper has something to do with raising fruit tenacity and reducing flesh crispness. The zinc in apple fruits is not remarkably related to storability and flesh texture, but good quality cultivars contain much little zinc.
