Associated fungi with seed of Sunflower

A total of /13/ fungal species belonging to /10/ genera have been obtained from nine samples of sunflower seeds. The isolation was on potato dextrose agar media and blotter paper with tow treatments (surface-sterilized seeds- seeds without sterilization). The species were Aspergillus flavus ; A. niger ; A. fumigatus ; ؛Alternaria alternate ; Fusarium solani; F. moniliforme ; Macrophomina phaseolina ; Mucor racemosus ; Penicillium chrysogenum ; Rhizopus stolonifer ; Trichotheium rosum ; Rhizoctonia solani and Absidia ramosae . The most prevalent species was Aspergillus flavus with percent frequency 100% and 55-77% for Alternaria alternata. The percentage of seeds germination was between (0-77%) on PDA media and (20-81%) on BP, and it was low in the non-sterile seeds treatment. The moisture content of the seeds was between (7.4-13%), and there is no correlation (R2=0.06) between the percentage of the infected seeds and its moisture content.
