Identification and effects of maize silk volatiles on cultures of Aspergillus flavus.

Volatiles emitted from silks of different maize genotypes had a profound effect on the growth of Aspergillus flagvus and, consequently, on aflatoxin production. To determine the underlying cause for this bioactivity. Volatiles emitted from the maize silks were trapped on Thnax glass columns and were analysed by GC-MS. Aflatoxin field-resistant maize gonotypes exhibited a larger relative concentration of the antifungal aldehyde, furfural Z2-furancarboxaledhyde), when compared to the relative concentrations of the field-susceptible varieties tested. In a closed container study, it was observed that freash 1 and 4 day old corn silk samples of aflatoxin-resistant maize genotypes emitted higher concentrations of furfural compardd to those from susceptible genotypes.
