Onion storage ability and an inventory of onion post-harvest fungi in Tunisia

Of 13 onion cultivars, red onions had longer storage life than white onions. Storage life was correlated with dry matter content. Botrytis spp., Aspergillus spp., Fusarium oxysporum and Penicillium spp. were frequently isolated from rotted bulbs. Fusarium oxysporum pathogenicity tested on healthy bu...

Description
Summary:Of 13 onion cultivars, red onions had longer storage life than white onions. Storage life was correlated with dry matter content. Botrytis spp., Aspergillus spp., Fusarium oxysporum and Penicillium spp. were frequently isolated from rotted bulbs. Fusarium oxysporum pathogenicity tested on healthy bulbs led to a typical basal rot; this is the first report of Fusarium oxysporum f.sp. cepae in Tunisia. Copyright © 2006 John Wiley & Sons, Ltd
