Identification and pathogenicity of Penicillium spp. isolated from onion seeds

Abstract

Onion seed production is performed over 600 ha in Mendoza and San Juan provinces, Argentina. Colonies of Penicillia are normally found on seed blotter tests and reported as contaminants, but no evidence has been found about efforts to identify pathogenic seedborne strains of Penicillium on onion seeds.The aim of this work is to isolate and identify colonies of Penicillium spp. and to investigate its pathogenicity.
