An association was found between C6-C12 alkanal and alkenal volatile contents in several maize genotypes, and aflatoxin contamination. Volatiles generated from untreated, ground, field resistant maize kernels affected growth and aflatoxin production by Aspergillus flavus when spores were inoculated on potato dextrose agar in a closed, sealed Petri dish assay. C6-C12 aldehydes were more prominent in the GC/MS total ion chromatograms of the resistant genotypes. Maize genotypes that exhibited a greater inhibition of aflatoxin production also exhibited a larger concentration of linoleic acid in their fatty acid profiles. These results suggest the correlation of decay products of polyunsaturated fatty acids arid plant disease resistance and indicate that the lipoxygenase pathway may contribute to this resistance.
