Eleven-kilogram parcels of 2-row and 6-row barley initially at 18% moisture content were implanted in dry bulk oats in a farm granary in Manitoba for 60 weeks between August 1983 and October 1984. Temperature, moisture content, O2 and CO2 levels, fat acidity values, seed germination, microfloral incidence and abundance and the presence of major mycotoxins (aflatoxins, sterigmatocystin, ochratoxin A, citrinin, penicillinic acid, patulin) were monitored. Ochratoxin A reached maximum levels of 0.97 ppm by week 24 in the 6-row barley, and 0.05 ppm by week 28 in the 2-row; no other mycotoxins were detected. The effect of cultivar type was significant (P less than 0.01) with greater effects in the 6-row barley for the following parameters: fat acidity value, germination, incidence of Alternaria alternata, Penicillium spp. and Helminthosporium sativum, total fungal propagule count and ochratoxin A levels. The effect of time was significant (P less than 0.05) for all variables except oxygen, carbon dioxide, Aspergillus versicolor, and total fungal propagule count. The interaction between cultivar and time was significant (P less than 0.01) for Alternaria and Helminthosporium only.
