Use of Self-Organizing Map to Analyze Images of Fungi Colonies Grown fromTriticum aestivumSeeds Disinfected by Ozone Treatment

[摘要] We submitted to ozone treatmentTriticum aestivum(common wheat) seeds severely contaminated by fungi. Fungi colonies developed when seeds were placed over malt agar medium in Petri dishes;Fusarium sp. andAlternaria sp. were identified. However, conventional colonies counting did not allow a clear assessment of the effect of ozone disinfection. We thus used self-organizing maps (SOMs) to perform an image analysis of colonies surface area that clearly showed a significant disinfection effect onFusarium sp.
