Resumen : | To detect and quantify Aspergillus flavus (FV), Fusarium
verticillioides (FV), aflatoxin (AFLA) and fumonisins (FUM) on maize
grains was tested in Sabana de Parra, Yaracuy State, Agua Blanca
and Santa Cruz de Turén, Portuguesa State during the dry season of
2005-2006 cycle and San Javier, Yaracuy State during the dry season
of 2006-2007. Fungal incidence was determined by direct seeding of
whole grains, disinfected, on malt salt agar. The content of AFLA
and FUM in Sabana de Parra, Agua Blanca and Santa Cruz de Turén
was determined by specific immunoassay. In San Javier AFLA
quantification was performed by ELISA and specific immunoassay
FUM. In Sabana de Parra, Agua Blanca and Santa Cruz de Turén
significative differences between genotypes in the incidence of AF
and FV, and not significative for the contents of AFLA and FUM were
detected. In San Javier significative differences in the contents of
AFLA and FUM, and not significative for AF and FV were observed.
The incidence of AF was low in Agua Blanca and San Javier, low in
Sabana de Parra except P30F94 and low to high in Santa Cruz de
Turén. The incidence of FV was low in Sabana de Parra, and low to
high in the other localities. In Sabana de Parra FUM and AFLA
contents were low and just under the limit permissible, but in the
other localities several samples exceeded 20 ng/g maximum permitted
tolerance.
Additional key words: aflatoxins, fumonisins, Zea mays. |
