Fusarium oxysporum and F. solani, causal agents of wilt and rot root in citrus seedling are variable pathogens. This study was conducted on the effect of different media in characters, sporulation, and spore germination of fusarium spp. Isolates that were isolated from seed and seedling of citrus. The data revealed that the maximum mycelial growth was obtained in most isolates on Potato Sucrose agar for F. oxysporum and F. solani, followed by Potato Dextrose agar for F. oxysporum, and by Czapek’sDox agar for F. solani. The maximum sporulation was recorded in Potato Sucrose agar medium followed byCzapek’sDox agar . The study also showed that Potato Dextrose agar was the best for germination of spores.

Research summary
تتناول هذه الدراسة تأثير مستنبتات مختلفة على بعض خصائص عزلات فطر الفيوزاريوم، التي تسبب ذبول وأعفان جذور غراس الحمضيات. تم الحصول على عزلات الفطر من بذور وبادرات الحمضيات، وتمت زراعتها على مستنبتات مختلفة مثل Potato Sucrose Agar (PSA)، Potato Dextrose Agar (PDA)، وCzapek's Dox Agar (CDA). أظهرت النتائج أن مستنبت PSA كان الأفضل لنمو مستعمرات أغلب العزلات، يليه مستنبت PDA لنمو عزلات النوع F. oxysporum، ومستتبت CDA لنمو عزلات النوع F. solani. كما أظهرت النتائج أن أفضل تبوغ لغالبية العزلات كان على مستنبت PSA، فيما كان مستنبت PDA الأفضل لإنتاش الأبواغ. خلصت الدراسة إلى أن مستنبت PSA هو الأنسب لنمو وتبوغ عزلات الفيوزاريوم، بينما كان مستنبت PDA الأفضل لإنتاش الأبواغ.
Critical review
تعتبر هذه الدراسة مهمة لفهم تأثير المستنبتات المختلفة على نمو وتبوغ فطر الفيوزاريوم، الذي يسبب أمراضاً خطيرة للحمضيات. ومع ذلك، يمكن أن تكون الدراسة أكثر شمولية إذا تم تضمين مستنبتات إضافية أو ظروف بيئية مختلفة. كما أن الدراسة تركز بشكل كبير على الجوانب المورفولوجية دون التعمق في الجوانب الجينية أو البيوكيميائية للفطر. بالإضافة إلى ذلك، كان من الممكن أن تكون الدراسة أكثر فائدة إذا تم تطبيق النتائج على نطاق أوسع من المحاصيل الزراعية وليس فقط الحمضيات.
Questions related to the research
  1. ما هو المستنبت الأفضل لنمو عزلات فطر الفيوزاريوم حسب الدراسة؟

    المستنبت الأفضل لنمو عزلات فطر الفيوزاريوم هو Potato Sucrose Agar (PSA).

  2. ما هي العزلات الفطرية التي تم دراستها في البحث؟

    تم دراسة عزلات فطر Fusarium oxysporum وFusarium solani.

  3. ما هو المستنبت الأفضل لإنتاش الأبواغ؟

    المستنبت الأفضل لإنتاش الأبواغ هو Potato Dextrose Agar (PDA).

  4. ما هي التوصيات التي قدمتها الدراسة؟

    أوصت الدراسة بدراسة الصفات المورفولوجية لأنواع الفيوزاريوم الأخرى واستخدام مستنبتات أخرى لدراسة فطر الفيوزاريوم عليها.

The experiment was carried out at the research stations of Salo in Deir- Azzor agricultural research center and Tel Sandal in Idlib agricultural research center. Land plots infected previously with sesame wilt disease, Macrophomina phaseolina (Tas si) Goid, and Fusarium oxysporum Schlecht were cultivated for two growing seasons (2007 and 2008) with medicinal species such as, Cumin (Cuminum-sativum), Black seed (Nigella sativa L.) and Fenugreek (Trigonella foeniculum L.) and another infected plot was left blank as a control plot. Zuri, a local sesame variety, was cultivated in all plots for two growing seasons (2008 and 2009). Results showed that the control plots had the highest percentage of infected sesame plants compared to the lowest percentage found in those plots that had been cultivatd previously with Black seed, Cumin, and Fenugreek. Plots cultivated previously with Black seed gave the highest sesame yield and followed by those plots of Cumin. The The average percentage of germination of sesame, as a phenological growth indicator, was increased in those plots planted before with Cumin and the average number of capsules per plant was increased at both locations by 36.75 capsules after Black seed in comparison with the control.
A field survey for chickpea wilt disease Fusarium oxysporum f.sp ciceris was conducted in different provinces of north Syria during 2011 cropping season with the objectives to determine chickpea wilt distribution and factors affecting its develop ment. Two hundred and fifty samples were collected from Alhasakah, Aleppo and Idleb fields. The results showed varying levels of incidence between and within provinces (2-90%), and the highest incidence was recorded in Alfouaa- Idleb (90%). The incidence and distribution of this disease seemed to be affected by many factors especially date of sown and soil kind. The pathogenicity test of 60 isolates related to Fusarium oxysporum on susceptible cultivars Ghab1 was shown that 54 isolates related to Fusarium oxysporum f. sp. ciceris; 32 isolates of them were caused yellowing symptoms and 22 were caused wilting symptoms.
The effect mycorhizal fungi on tomato wilt disease caused by Fusarium oxysporum was studied. The results showed that % of disease incidence reduced in treatment whit mycorrhizal fungi . % of disease incidence reached to 33% when plants infected wit h mycorrhizae and Fusarium wilt compared to plants infected with Fusarium wilt just where% of disease incidence reached to 70% .The results showed a sighificant increased in plant height ,leaf number , fresh and dry matter of shoot and root in treated plants with mycorrhiza and Fusarium wilt compared whit treated plants with Fusarium wilt.The increase in plant height reached 24.13% ,16.93% in leaf number,36.13% in wet weight of shoot ,48.14 in wet weight of root,30.37% in dry weight of shoot and 29.18% in dry weight of root in treated plants with mycorrhiza and Fusarium wilt.
In order to evaluate the important role of climate on soil formation, three different locations (Nawa, Dael and Nasib) in southern part of Syria, representing the North West, Middle and Southern parts of Hauran Plateau were selected and differ mai nly in the amount of annual precipitation and relatively with other factors. Three profiles, replicated three times, were prepared one profile for each area.
