Abstract: 

The aim of search was to investigate the presence of field fungi and storage fungi on Syrian wheat hard and soft, stored in the concrete silos for two consecutive years, collected (control samples) during purchases immediately after the harvest of the 2012 season in Center Silos of Kalet-Almdek Hama, sorted by the category of second degree hard wheat (S2/2) and Second Degree Soft Wheat (S4/2), stored separately in a large cell 1,200-ton, studied the colonies Alternaria and Fusarium from the field fungal and the colonies of Aspergillus and Penicillium from the fungal stores. The results showed a decrease in the number of colonies of field fungal Alternaria from183.67 to 9.17 and Fusarium from2.26 to 0.9 CFU/g for hard wheat, as soft wheat Alternaria from 2.24 to 1.27 and Fusarium from 2.27 to 0.92 CFU/g, with significant differences in continuing storage operations during the first six months, and then stabilizing during the last 18 months of storage. The study also recorded increased by significant differences the number of fungal colonies stored on Aspergillus hard wheat (1.27 to 2.78) CFU/g and Penicillium from1.04 to 2.62 CFU/g, as on soft wheat Aspergillus from 1.26 to 2.79 CFU/g and Penicillium from 1.03 to 2.63 CFU/g, with a significant differences between them in increase of Aspergillus in grains stored in concrete silos from June 2012 to June 2014, significant increase their number in the last six months of storage for both hard and soft wheat.
