دراسات على الفلورا الفطرية لساحل البحر الأحمر بمحافظة القنفذة المملکة العربية السعودية STUDIES ON THE MYCOFLORA OF THE RED SEA COAST AL QUNFIDAH REGION, SAUDI ARABIA

Document Type : Original Article

Abstract

الملخص :




تم في هذه الدراسة الکشف عن الفطرياتفي 27 عينة تربة جمعت على امتداد ساحل البحر الأحمر لمحافظة القنفذة بالمملکة العربية السعودية، کما تم تحليل التربة کيمائيا وفيزيائيا وقد أثبتت النتائج أن عينات التربة المختبرة ذات محتوى فقير في المادة العضوية ونسب مختلفة ضئيلة من الرطوبة النسبية وتحتوي على نسب قليلة ومتفاوتة في الأملاح الکلية الذائبة وکان الرقم الهيدروجيني للأنواع المختلفة من التربة التي حللت يتراوح بين 7.1-7.4. أما العناصر السالبة والموجبة (الانيونات والکاتيونات) فقد کانت متفاوتة ووجد أن الکلوريدات والکبريتات والصوديوم والبوتاسيوم عالية في بعض العينات بالنسبة للعناصر الأخرى.
 عند درجة حرارة  28±2مْ تم عزل وتعريف 34 نوعا فطريا وصنفان من الاسبرجيللس Aspergillus تنتمي إلى 21 جنسا فطريا، وعزل جنسAspergillus  بکثافة بنسبة 51.01% تلاها جنسPenicillium وعزل بنسبة 50.08٪  ثمجنسي Botryotrichum و Chrysosporiumوعزلا بنسبة مئوية 32.61 و 31.38٪ على التوالي، أما Nectria فقد عزلت بنسبة 22.89%.  وعزلت باقي الأجناس بنسب مئوية منخفضة وهي:
 Fusarium,Alternaria, Chaetomium, Hormodendrum,Gilmaniella, VerticilliumFennellia, Mucor,Setosphaeria,Phoma,Cochliobolus,Syncephalastrum,  Rhizoctonia, Blastomyces,Humicola,   andCurvularia.
 عند درجة حرارة 45±2 م ْ تمعزل 5 أنواع فطرية تنتمي إلى 4 أجناس فطرية فقطحيث نمت الفطريات في 11 عينة فقط من ال 27 عينة عند هذه الدرجة ممثلة في أربعة أجناس فطرية فقط متحملة للحرارة وهي:  Blastomyces,Nectria,Aspergillus andFusarium.
 
Twenty seven samples were representing different localities along the red sea coast in Al-Qunfidah region, Soil fungi were isolated and identified. The soil samples were tested, generally, were poor in their organic matter content, different in the total soluble salts, moisture and total metal content, the pH value were generally neutral. At 28±2ْC (mesophilic fungi) 34 fungal species in addition to 2 varieties of Aspergillus which belong to 21 genera were isolated and identified. The most common fungal genera were  Aspergillus 51.01%,  Penicillium 50.82% , Botryotrichum followed by Chrysosporium, 32.61% and 31.38% respectively, Nectria 22.89% Whereas the following genera  Fusarium, Blastomyces, Humicola, Curvularia, Alternaria, Chaetomium, Hormodendrum, Gilmaniella, Verticillium, Fennellia, Mucor, Setosphaeria, Phoma, Syncephalastrum, Cochliobolus and Rhizoctonia recovered in 3.22 – 0.07%.
At 45±2ْC, 4 fungal genera of thermotolerant fungi were isolated from 11 soil samples out of 27 soil samples, the most common genus was Blastomyces which represented 22.2% of the total fungi, Nectria, Aspergillus and Fusarium represented by 18.5%, 11.1% and 3.7% of the tested soil samples, respectively.
