The location of seedborne fungi in different parts of discoloured maize seeds was determined by seed component plating and microtomy. Seedborne inoculum of Bipolaris maydis [Cochliobolus heterostrophus] (responsible for black and white streaks), Botryodiplodia theobromae (responsible for black pointed dots), Curvularia lunata [Cochliobolus lunatus] (responsible for dark black streaks) and Fusarium moniliforme [Gibberella fujikuroi] (responsible for white streaks) were detected in all components (tip cap, pericarp, embryo and endosperm) of maize seeds, whereas Curvularia pallescens [Cochliobolus pallescens] and Bipolaris carbonum were detected in the tip cap and pericarp; and tip cap, pericarp and endosperm regions, respectively.
