هدف البحث إلى تحديد بعض أنواع الفطور الجذرية (الميكوريزا) المتعايشة مع جذور نبات البندورة في البيوت البلاستيكية في الساحل السوري. جمعت العينات من موقعي البرجان و سيانو في محافظة اللاذقية و مواقع حريصون و ميعار شاكر و مجدلون البحر في محافظة طرطوس. جمعت أربع عينات مكونة من تربة و جذور نبات البندورة من كل موقع، و خلطت مع بعضها لتمثل عينة مركبة. عزلت الفطور المتعايشة و ثم وصفت مورفولوجياً و صنفت وفقاً لمفاتيح التصنيف المعتمدة عالمياً. تم تحديد ستة أنواع من فطور الميكوريزا متعايشة مع جذور البندورة في مناطق الدراسة و هي Paraglomus laccaltum عزل من موقع سيانو فقط و Septoglomus constrictum عزل من موقعي ميعار شاكر و مجدلون البحر و Claroideoglomus etunicatum عزل من موقعي ميعار شاكر و سيانو و عزل Simiglomus hoi من مواقع سيانو و البرجان و حريصون و Glomus fasciculatum عزل من جميع المواقع باستثناء مجدلون البحر و Glomus clarum عزل من جميع المواقع باستثناء موقع البرجان.
The objective of this study is to identify some species of mycorrhizal fungi coexisting with tomato roots in the Syrian coast. Samples were collected from five sites in two different regions: Lattakia (sites: Siano and ALbrjan) and Tartous (sites: Majdalon Elbahr, Mayaar Shaker and Hrysoon). Four samples of soil and tomato roots were collected from each site and mixed together to form a composite sample/site. Morphological characterization of isolated fungi was based on universally adopted taxonomic keys, and on the classification keys approved by the Plant Protection Research Institute of Iran. Six types of mycorrhizal fungi belonging to 5 species were identified in the different sites. Paraglomus laccaltum was present in one site (Siano), Septoglomus constrictum was isolated from 2 sites (Mayaar Shaker and Majdalon Elbahr), Claroideoglomus etunicatum was also isolated from 2 sites (Mayaar Shaker and Siano), Simiglomus hoi was present in 3 sites (Siano, Majdalon Elbahr and ALbrjan), Glomus fasciculatum was present in four sites (Siano, Mayaar Shaker, ALbrjan and Hrysoon) and Glomus clarum was present in four sites (Hrysoon, Siano, Mayaar Shaker, and Majdalon Elbahr).

This research was done at Syrian coast (Lattakia and Tartous) where the research
information were gather from 4 distributor area in (Tartous, Banias, Jableh, Kerdaha)
during the period 2011-2012. (20) areas were choosed and Questionnaire was used w
ith
personality interview form for tomato farmers. The results signed to presence very strong
correlation (r = 0.968) between production as dependent variable (y) and planted area at
Syrian coast level as independent variable (x), whereas correlation was average (r = 0.620)
between productivity as as dependent variable (y) and area as independent variable (x).
The results also signed that (72.98%) of producing protectorate tomato was being
marketed to wholesale market, whereas (22.07%) of production was being marketed to
tomato past factories, (4.95%) was being marketed to processor factories for exterior
export.
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.
Objective:
To examine associations between hematological parameters ( hemoglobin,
hematocrit, platelet (PLT(, red blood cell (RBC), and white blood cell (WBC)) and
components of metabolic syndrome (MS) among the Syrian Coast population.
Methods:
Study subjects were 304 patients (140 men and 164 women), aged between 20-75 years,
who attended endocrine and cardiac clinic in Tishreen and Al-Assad University Hospitals
during the period from February 2015 to April 2016. MS was classified according to the
International Diabetes Federation criterion. Odds ratios (OR) and 95% confidence intervals
(95% CI) of MS were calculated using logistic regression procedures.
Results:
Hematologic parameters were significantly associated with MS components (Ptrend<0.05).
and they increased with increasing number of MS components in both men and Women,
All haematological parameters were positively associated with BMI, waist circumference,
Triglycerides and negatively associated with HDL in male and female subjects. Among
men, MS risk increased across successive quartiles of HB (OR= 4.43,9.27 and 10.18),
HCT (OR= 3.57, 6 and 7.2), PLT (OR= 2.19, 4.18 and 20.86), WBC (OR= 1.59, 5.7 and
7.13) and RBC (OR= 4.49,5.32 and 9.68) as compared with those in the lowest reference
group (P ≥ 0.0001). Among women, those in the highest quartiles of (HB, HCT, PLT ,
WBC and RBC) had respectively (1.26, 1.88, 10.93, 3.93 and 3.55)-fold increased odds of
MetS as compared with those in the lowest reference group. Our findings provide further
evidence in support of using hematological markers for early detection of individuals at
risk for MS.
This study was conducted in Tobacco fields in the Syrian coast to investigate Root-knot Nematode on two varieties of tobacco (Burley and Flue-cured). Two hundred and five samples of the roots of infected plants were collected from 32 fields in the pe
riod between early August and early October. The results showed that the degree of infestation was high (fifth degree) to Flue-cured tobacco (average was 179.20 knot for one sample), and fourth degree to the Burley tobacco (average 39.95 knot on one sample).
There were three species of Meloidogyne: M.javanica, it had the most frequency 46.25 % and 43.7 % of Burley and Flue-cured tobacco respectively, followed by M.incognita 26.25 % and 24.44% of samples respectively. These species were present together in less frequency on both studied varieties. Whereas the third specie M.arenaria only appeared in three sites of Flue-cured tobacco in less frequency (5.18 %) and was associated with M.incognita.
This study aims to investigate the means of the mesio-distal crown
width of CPMs, their correlations, gender discrepancies and
symmetry according to the sagittal plane in the Syrian Coast
population .The sample consisted of 300 students with a mea

age of 16.7 years old .
