Abstract
Foliar calcium applications in peach crops are a strategy that enhances postharvest fruit quality.
However, the differences between cultivars have not been extensively characterized.
Therefore, this study aims to define the potential differences between peach and nectarine cultivars in calcium absorption.
Foliar calcium was applied across different fruit sizes for two cultivars.
Parameters such as production, quality, and nutritional content of fruits were evaluated, along with storage capacity and postharvest quality.
Simultaneously, stable isotope 44calcium applications were applied at the same time to trace calcium movement into different parts of the fruit: epicarp, mesocarp, and endocarp.
Generally, peaches exhibited higher calcium enrichment compared to nectarines, and the epicarp was the most enriched part of the fruit, followed by the mesocarp and the endocarp.
Calcium absorption in fruits from external CaCl2 treatments was significantly influenced by the moment of application during fruit development.
Interestingly, for peaches and nectarines, the higher the fruit size at the time of application, the highest calcium content remained in the mesocarp.
In contrast, the smaller the fruit size at the time of application, the more calcium reaches the endocarp.
Overall, calcium absorption and distribution in peaches and nectarines depend on the cultivar and the timing of the application.
