Abstract


The objectives of this research were to classify fungal species associated with Zea mays L. grains, and to study the percentage of these fungi. Six tons of corn grains were used for the experiment, and were stored in-doors in warehouse of Animal Wealth Research Administration. Three samples were taken every three months (at the mid of every season) by using international sampling method (ISO 950). Results showed that the Fungi Associated with Corn were: Aspergillus spp., Penicillium spp., Fusarium spp., Mucor spp. and Rhizopus spp. And the species' of genus Aspergillus spp. were: Aspergillus flavus, A. niger, A. tamarii, A. oryzae, A. flavipes, A. versicolor, A. raperi, A. sydowii, A. penicilloides. There were dynamic series of fungi frequency, and the genus Penicillium was dominant in winter, summer and autumn, while, the genus Aspergillus was dominant in spring. The statistical analysis (ANOVA) showed that there were significant differences of percentage average between the existence of Aspergillus and Penicillium in comparison with other genera. whereas the higher percentage average of genus Penicillium was 53%, then the genus Aspergillus was 42.5%, then the genus Rhizopus was 2.2%, then the genus Fusarium was 1.3%, and finally the genus Mucor was 0.5%, in other words there was difference of genera existence between seasons. According to above results, it was concluded that warehouses storage of Corn in Syrian storage conditions was not safe.
