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.

The findings demonstrate the potential of PAs, especially SPD at 0.01 mmol L⁻¹, as an effective and sustainable tool to improve crop yield, mitigate CI and preserve the quality of 'Mollar de Elche' pomegranate fruit during cold storage. Thus, PA treatments would lead to an increase in growers' income and health benefits for consumers, due to the enhanced bioactive compound content.
