[Susceptibility of hybrid varieties of sunflower to the formation of aflatoxins].

Aflatoxin is produced on sunflower varieties and hybrids. Since it has been demonstrated that sunflower seed are a natural substrate for aflatoxin production in our country, 4 varieties and 11 hybrids were studied to determine aflatoxin susceptibility. The samples were analyzed after 7 days of inoculation with A. parasiticus NRRL 2999. The varieties and hybrids showed different capacity of toxin production being the varieties more susceptible than the hybrids.
