Factors Affecting Fruit Quality in Strawberries Grown in a Subtropical Environment

摘要

Variations of strawberry fruit quality due to year, harvest date, cultivar, and nutrition were studied in Tucumdn, Argentina. 'Camarosa', 'Camino Real', 'Candonga', and 'Ventana' were fertilized with "C" (control; 120 kg N/ha, 70 kg P_20_5/ha, 220 kgK2Ofha, 40 kg CaO/ha, and 20 kg MgO/ha) and "1.5C" in 2006, "C", "1.33C", and "1.66C" in 2007, and "C", "1.5C", and "2C" in 2008, without affecting fruit quality. Fruit weight decreased with temperature and crop load. Firmness decreased with rainfall andtemperature. Redness increased with temperature and decreased with rainfall. Soluble solids content decreased with crop load. Titratable acidity increased with temperature.
