| Sumario: | Pomegranate (Punica granatum L.) cultivation in southern Italy has recently
gained increasing interest due to putative beneficial effects on human health. Both, in
the field and postharvest product losses, especially in organic fruit production,
represent the chief concern for this high-priced chain. Main postharvest pomegranate
diseases are caused by latent pathogens that infect pomegranates during blooming
stage (Coniella granati, Alternaria spp., Botrytis spp.), and secondarily by wound
pathogens (Penicillium spp., Talaromyces spp., and Aspergillus spp.) affecting fruit
during processing from harvest until the end of storage and shelf life. The aim of this
research was to test the in vitro effect of alternative control means already present on
the market, suitable for controlling pomegranate postharvest pathogens. Particularly,
the effectiveness of a red seaweeds extract, a plant protein hydrolysate, and a chitosan
solution were compared to fludioxonil (chemical control) and water (not treated
control) assessing the mean growth diameter reached by each fungal colony at the end
of the incubation. Chitosan behaved as the most effective substance in controlling all
postharvest pomegranate fungal pathogens. This work was conducted within the
framework of the PRIMA StopMedWaste project, which is funded by PRIMA, a program
supported by the European Union. |
