Abstract : |
Twenty three samples, belonging to 19 corn cultivars with distinct types of germoplasms, endosperm and length of vegetative cycle, were analyzed for fumonisins B1 and B2. The cultivars were grown in experimental fields in three locations (Votuporanga, Ribeirأ£o Preto and Capأ£o Bonito) within the State of Sأ£o Paulo, Brazil, during the 97/98 crop. All samples were contaminated with fumonisins with concentrations ranging from 1.63 آµg/g to 25.69 آµg/g with an average of 5.61 آµg/g for FB1 and from 0.38 آµg/g to 8.60 آµg/g with an average of 1.86 آµg/g for FB2. In terms of fumonisins, these high levels put the corn cultivated in Sأ£o Paulo among the most contaminated in the world reported to date., |
