Agronomic Approaches to Enhance Kiwifruit Calcium Content and Investigate Its Impact on Fruit Physiology

Аннотация

Kiwifruit (Actinidia spp.) is a highly nutritious fruit valued for its rich content of vitamins, antioxidants, and minerals, particularly calcium, which plays a crucial role in its physiological processes. Calcium influences several aspects of kiwifruit growth, quality, and shelf-life, yet the optimal strategies to manipulate its levels remain under exploration. This paper reviews agronomic strategies aimed at increasing kiwifruit calcium content, including soil amendments, foliar applications, rootstock selection, and the use of controlled environments. Through a detailed analysis of these strategies, we aim to better understand the relationship between calcium content and fruit physiology, including its impact on fruit firmness, ripening, and resistance to physiological disorders. The findings suggest that while calcium plays a key role in kiwifruit quality, effective agronomic interventions are essential for optimizing its levels and improving overall fruit production. Future research in this area will provide valuable insights for advancing sustainable and high-quality kiwifruit production.
