| Materials and methods: Nine fungal isolates namely Emericill anidulans, Mucor racemosus , Alternaria pluriseptata Penicillium canescens, Syncephalastrum racemosum, Aspergillus fumigatus, Alternaria chlamydospora, Aspergillus parasiticus and Ulocladium atrum were isolated from AL – SHEGA area at AL- QASSIM region. Results: The influence of different sodium chloride concentrations on the growth rate, morphological and ultrastructure were studied. Considerable differences in their growth rate and morphology were detected on medium containing different concentrations of sodium chloride (NaCl). Low growth rates were obseved on high NaCl concentrations . At 15 % NaCl, low growth of Emericill anidulans, Penicillium canescens, Syncephalastrum racemosum, Aspergillus parasiticus and Mucor racemosus was detected , whereas all fungal isolates were failed to grow at 20% NaCl. Scanning Electron Microscope (SEM) revealed that all fungal asexual reproduction organs were metamorphosed at higher NaCl concentration, fungal heads and sporangia were speculated or elongated. Sporangiophores and conidiophores were shortened and dwarfed ,little number of conidia or spores were detected. | ||
