Relationships between seed germination, fumonisin content, and Fusarium verticillioides infection in selected maize samples from different regions of Costa Rica.

Thirty five maize seed samples from three geographic regions of Costa Rica were analysed for fumonisin content, germination and Fusarium verticillioides infection. The concentration of fumonisins in the maize samples varied from 4 to 16,000 mg/kg with an overall average of 2,500 mg/kg. There was a significant difference in fumonisin content between samples freom Alajuela and Guanacaste. There was a significant negative correleation between fumonisin content and seed germination, but no significant correlation was found between fumonisin content and F. verticillioides infection, or between F. verticillioides infection and seed germination. Most of the high fumonisin seed samples had some mechanical or insect damage.
