تعد مسببات ذبول و عفن جذور غراس الحمضيات Fusariumoxysporum و F. solani ممرضات متنوعة, أجريت هذه الدراسة لمعرفة تأثير مستنبتات مختلفة في الصفات المورفولوجية, التبوغ و إنتاش الأبواغ لعزلات من جنس فيوزاريوم تم الحصول عليها من بذور و بادرات حمضيات. أظهرت النتائج أن مستنبت PSA كان الأفضل لنمو مستعمرات أغلب العزلات تلاه مستنبت PDA لنمو عزلات النوع F.oxysporium, و المستنبت CDA لنمو عزلات F.solani.كما أظهرت أن أفضل تبوغ لغالبية العزلات كان على مستنبت PSA تلاه مستنبت CDA .و كان مستنبت PDA هو الأفضل لإنتاش أبواغ غالبية العزلات.
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.

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.
The effect of six bacterial isolates of Proteus genus were studied the on
causative of Fusarium axysporum f.sp ciceris in both the glasshouse and
the field.
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.
