نفذ هذا البحث خلال العام 2015 بهدف معرفة بعض المركبات الكيميائية لثمار عدد من طرز خوخ الدب Prunus ursina K.y المنتشرة في مواقع مختلفة من المنطقة الغربية من سورية. حددت ستة مواقع طبيعية لانتشار هذا النوع (دوير بسنديانة - النبعين - الشوح طي - حيلاتا - بتمازة -وادي حيلين)، إذ تم دراسة (35) طرازاً من حيث النسبة المئوية للسكريات الكلية، و النسبة المئوية للحموضة الكلية T.A، و نسبة المواد الصلبة الذائبة T.S.S، و المادة الجافة في الثمار في مرحلة النضج. أخضعت المعطيات لتحليل التباين ANOVA باستخدام برنامج التحليل الإحصائي Costat و جرت المقارنة بين المتوسطات عند مستوى معنوية 5%، بينت النتائج تفوق الطرز K6-KAB1-KA3 معنوياً على بقية الطرز من حيث المادة الصلبة الذائبة بنسب بلغت (22-22.1-22)% على التتالي، في حين تفوق الطرازان M1-M2 معنوياً على بقية الطرز من حيث محتوى الثمار من السكريات الكلية بنسبة بلغت 13.75% في كلا الطرازين، أما الطراز K1 فقد تفوق معنوياً على بقية الطرز من حيث محتوى الثمار من الحموضة بنسبة بلغت 4.9%، في حين تفوق الطراز K2 معنوياً على بقية الطرز من حيث محتوى الثمار من المادة الجافة و بلغت النسبة 30.5%. بينت شجرة القرابة باستخدام برنامج NTSYS توزع الطرز المدروسة ضمن مجموعتين (A-B) بناءً على الخصائص الكيميائية للثمار. يتبع المجموعة الأولى A الطرازان (J6-KAB5) المتواجدان في موقعين متباعدين جغرافياً و هما بتمازة و دوير بسنديانة، في حين تتبع بقية الطرز إلى المجموعة B و تنتشر في جميع مواقع الدراسة.
This study was carried out during 2015to determine some chemical Composition of the fruit of some distribution phenotypes of Prunus ursina in different regions of Westrens of Syria. six natural distribution sites were determined(Duerbsndiana-Alnabeen-Alshohtte- Helata-Btmazah-Wadeheleen), and 35 trees were determined as samples. Fruits were harvested and following parameters were determined: dry matter, total acids (T.A), total soluble solids (T.S.S), and total sugar. Statistical analysis of investigated phenotypes showed that There were differences between dry matter, total soluble solids (T.S.S), and total sugar between two groups. the trees were distributed in two groups (A, B) .The results showed existence of most trees in whole sits, while (J6 and KA6) were distributed in two different sits(Btmazah and Duerbsndiana) .

This study was carried out during 2011- 2013 to determine some qualitative and
quantitative features of some distribution trees of Prunus ursina in different regions of
Syrian coast.7 natural distribution sites were determined and 43 trees were det
ermined as
samples.
22 features of different plant portions were studied using biological
measurements(leaves, flowers, fruits, seeds). Statistical analysis of investigated phenotypes
showed that trees were distributed in 5 groups (A, B, C, D, E) each one considered
phenotype. The results showed existence of one phenotype in several sites (C, D, E) while
(A and B) phenotypes were distributed in one site, while (A) phenotype was located in one
tree only in " Nabeen" site whereas (B) phenotype was located on only half investigated
trees in "Btmaze" site, while the other half distributed in (D) phenotype.
Terebinth trees have been occupying a good part of the mount of Syrian
(abed elaziz, pelass). The Pistacia atlantica fruit, rich in oil, is used by local
inhabitants in many ways, few studies investigation of the P. atlantica fruit oil
of Syria ha
s been carried out,This study investigates the protein, ash, crude oil
and oil composition of P. atlantica with respect to total phenol, iodine value and
saponification value, in order to classify it among the other known edible oils
thenafter compare the oil composition with the oils of other Pistacia species.
The fruit of P.atlantica appears to be rich in oil. The major fatty acid in the
sample studied are oleic, linoleic, our results show that. The oil has a higher
content of unsaturated FA (oleic + linoleic = 72%). The oil can be classified as
an oleo-linoleic vegetable oil. The biochemical data showed an elevated MUFA
content (50-48%) which may constitute an important property against certain
pathologies for its nutritional and preventive virtues.
Carob pod is the fruit of the carob tree (Ceratonia siliqua L.). The
fruit and its products, sold both in large stores and local markets,
contribute strongly to the diet of people living in the Mediterranean areas
of Europe.
This study reports th
e composition of carob pods sampled in
Homs, Hama and Coast Regions
This research was conducted in Agriculture College (Food Science Dep.,
Damascus U university). The purpose of this research was to evaluate Cherkes
Cheese by determination some Chemical and microbial properties for 40
samples collected randomly fr
om different places Damascus and country sides.
The results showed very deferent changes in Chemical properties. The acidity
ranged between (0.25 - 0.54%), moisture content (38 - 56%), and total dry
matter (44 - 62.7%). Results also showed that all samples were rejected by
(Syrian Normal Standard)for fat content in dry matter (20 -33%). Fifty percent
of samples were rejected for their content of sodium chloride which was
(1.2 - 4.3%). Results also showed that samples were free of Salmonella and
there was no rejection for existence of Staph. aureus but 37.5 % and 10% of
samples were rejected by (Syrian Normal Standard)as per content of coliform
and E.coli, respectively.
This research was carried out during two seasons 2014 – 2015 to study effect of seed
coats on germination of endocarp, seed and embryos of two wild genotypes (M1, M2) of
Mahaleb rootstock (Prunus mahaleb L.) prevailing in Alhaffa area, Lattakia. Th
e
experiments were done at Lattakia Scientific Agricultural Research center and Faculty of
Agriculture at Tishreen University.
The Results of the seeds planted on agar 0.7% in dark at 15 C° showed that no
germination of the M1 endocarp VS late and low germination at 10% for the M2 endocarp
starting after 98 days. As for seeds, the germination was (66.66%) and (53.33%) for M1
and M2, respectively. Removal of the woody coat (endocarp) and seed coat makes the
germination faster. the embryos germination was (80%) and (60%) for M1 and M2,
respectively.
