ACCUMULATION OF THE MYCOTOXIN BEAUVERICIN IN KERNELS OF CORN HYBRIDS INOCULATED WITH FUSARIUM SUBGLUTINANS

摘要

The accumulation of the mycotoxin beauvericin (BEA) after artificial inoculation of corn ears with Fusarium subglutinans is reported here for the first time. Ears of nine hybrids have been examined using a trace analytical method capable of detecting BEA down to 0.05 mg/kg (recovery 82.6%). Fusarium-damaged kernels contained 6.5-15.8 mg of BEA/kg and healthy looking kernels 0.07-0.13 mg of BEA/kg. The hybrids Mona and Anna, which showed the lowest susceptibility to Fusarium ear rot, accumulated the lowest amounts of BEA in the total ear, on average 0.40 and 0.85 mg/kg, respectively. Ears of the remaining hybrids accumulated 1.02-5.77 mg of BEA/kg.
