• Resumen

  • The postharvest storage of ‘Mollar de Elche’ pomegranate fruit during long periods, around 3 months, in optimum conditions (6-9ºC), could increase chilling injury incidence accompanied with quality losses of pomegranate fruits. In this experiment, the effect of methyl jasmonate (MeJa) at 5 mM, such as elicitor, by foliar treatment was study. This treatment was applied in differents plots, safeguarded by Protected Designation in Origin (PDO). The results showed that this preharvest treatment reduced a 40-60 % of chilling injury incidence in the internal and external husk compared to the untreated fruits during postharvest storage. On the other hand, treated fruits showed a greater physical-chemical property than control, leading into a higher fruit acceptability by consumers.
