تأثير بعض المواد الكيمياوية و العوامل الفيزياوية و الكيمياوية على عزلتي فطر Alternaria sp. المسببة لتلف بعض أنواع الحبوب المخزونة و الأغذية المحلية و المعلبة

Abstract EN

The present research studys the effect of some biological and physiological materials on the two isolations Alternaria sp.

The study includes the effects of some species from cultures media on the Alternaria sp.

Growth , it is found that the difference between the two isolations from appearance side in the dishes or microscope .Cultures media appearance is high efficiency in growth fungus Alternaria alternata and get diameter of the colonies as to isolation Alternaria teunissima .Therefore Alternaria teunissima as to isolation appearance on the (PDA) media ,as well as that the effect of a number of chemical materials on the species of Alternaria sp are represented in (sodium chloride ,sucrose ,sodium citrate, sodium carbonate) and it is noticed that their effect on the two isolations with the choice number of concentration it and it is observed that the efficiency on tow isolations .Also it is observed that the effect of the number of heating degrees on isolation and that it used to keep the nutrient , as well as the choice bacillin of fungicide that it is used in that protecting of crops from and prevention the rot getting rather observing it effect on the tow isolations.
