Polyamine treatments: an effective strategy to improve crop yield and fruit colour and to preserve quality of ‘Mollar de Elche’ pomegranate fruit during storage at chilling temperatures

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change in Spain is altering the optimal conditions for producing high‐quality ‘Mollar de Elche’ pomegranate fruit, due to reduced colour development in husk and arils. In addition, the pomegranate requires storage above 7–10 °C, depending on cultivar, to preserve its quality because it is susceptible to chilling injury (CI ...
