نفذ هذا البحث خلال العامين 2011 و 2013 بهدف تحديد بعض الموصفات الكمية و النوعية لبعض أشجار خوخ الدب Prunus ursina K.y المنتشرة في مناطق مختلفة من الساحل السوري. حددت سبعة مواقع طبيعية لوجود و انتشار تلك الأشجار، و من ثم حددت (43) شجرة لإجراء الدراسة عليها، استخدمت القياسات الحيوية على 22 صفة لأجزاء النبات المختلفة (أوراق- أزهار- ثمار- نوى). بين التحليل الإحصائي للصفات الكمية و النوعية للطرز المدروسة توزع تلك الأشجار ضمن خمس مجموعات ( A-B-C-D-E) اعتبرت كل منها طرازا مظهريا. و قد أظهرت النتائج انتشار طراز مظهري واحد في عدة مواقع مثل الطرز (C-D-E) التي انتشر كل منها على حدة في أكثر من موقع، بينما الطرازين (A-B) انتشرا في موقع واحد حيث ظهر الطراز (A) على شجرة واحدة فقط دون غيرها في موقع النبعين في حين ظهر الطراز (B) في موقع بتمازة على نصف الأشجار المدروسة فقط بينما توزع النصف الآخر ضمن الطراز (D).
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 determined 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.

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-Alnab
een-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) .
Morphological and molecular characterization for six seedling genotypes of
Pistachio vera L (V1,V2,V3,V4,V5, and V6) in comparison with the most
commercial and wide spread varieties, Ashoury andWhite batoury was carried
out in Swaida province, sou
thern of Syria. Nuts chemical contents (dry
substance, moisture, total sugar and oil content) for both fresh and dry nuts
weight were also evaluated.
Seedling genotypes showed obvious differences toward the main diagnostic
traits, such as alternate bearing phenomena, the ratio of kernel weight to total
nut weight, split nuts percentage and loss percentage. Genotype V4 was
recognized by some important characters compared with the other genotypes
studied. Cluster analysis was assessed according to the existence or absence of
the most important studying morphological and agronomic indexes. All
genotypes studied and comparative cultivars were clustered into four groups.
RAPD technique was achieved using 25 randomly primers, 19 of which were
polymorphic with an average of polymorphism percentage of (66.47%). The
highest value of genetic similarity (0.81) was between Ashoury and V5
genotype, whereas the lowest value (0.56) was between V3 and V6. Cluster
analysis depending on RAPD data divided the population studied into two main
groups. RAPD unique band was estimated (37 unique band, 21 positive and 16
negative).
It was concluded that RAPD technique can be used efficiently to emphasize,
identify, insure and evaluate the genetic diversity of Pistachio vera.
This research was conducted to detect the morphological and molecular
differences between golden henbane (Hyoscyamus aureus L) collected from
south Syria. Seeds were collected from six locations, then sterilized and grown
In Vitro. Grown plants we
re described for some morphological characters. The
molecular characterization was carried out using the method of Inter Simple
Sequence Repeats (ISSR) to detect genetic variations. The plants showed
significant (p<0.01) morphological differences among studied locations, Plant
height ranged from 14.97 to 18.97 cm and stem color ranged from red to green.
Trichome density also ranged between medium, high and very high.
Furthermore, significant differences in leaves dimensions were observed
according to the plant geographical location. The main root length ranged from
6.09 to 8.37 cm. Molecular analysis by ISSR produced a total of 56 bands, 49 of
which were polymorphic (87.5%), resulted from using 11 non-specific primers.
A genetic distance dendrogram was drawn. based on the results of genetic
characterization of plant from different locations. The plants collected from
Salkhad separated with a genetic distance of 0.312 while the plants collected
from other locations were grouped together, at the same time, they were
divided into two sub groups, the first group comprised plants collected from
Qalamoun and Dimas regions with a genetic distance of 0.032, whereas sub
group II content Bosra plants which separated clearly from those of Dara' dam
and Wadi Al-Zaidi by a genetic distance of 0.017, These results may indicate a
relationship between genetic characters of this plant species with geographic
distribution.
The study has been done in many farms which are producing sweet
cherry in Lattakia during the season (2014-2015).
This research focuses on study timing of phonological stages of
sweet cherry in two regions (sluonfa , aen alhaeat) in Lattakia ciety
and studies the effect of some climatological conditions like
temperature and rain on this plant .
The result of this study revealed clear variation in the climatological
conditions between the two regions under study.
T his variation in climatological conditions led to variation in the
phonological stages of sweet cherry in two regions under study.
Morphological Characterization Has Been Achieved For (10) Phenotype Wild
Apple(Malus trilobata (Lab) ) In JABLEH mountains During The Period (2013-2014) In
Five Area (Pichraghe, Helbako, Almonaizlah, Raas al chaara, Aldalia),In Height Between

-1250) m On See Standard, Morphological Characterization Included The
Characteristics Of The Tree, Stem, Shoots, Leaves, Flowers, Fruit And Seed. The Cluster
Analysis For (12) Characteristics Were Divided Into Two Groups Variation Ratio Even (57
%) , The First Group Included Four Types(Two Types Of Rass al chaara(R1, R2), One
Type Of Pichraghe(P1) And One Type Of Almonaizlah(M2) ), Variation Ratio Was The
Least(29.4%) Between (P1) And (R1), The Second Group Included Six Types (Tow
Types Of Pichraghe (P2, P3), Two Types Of Helbako, One Type Of Almonaizlah(M1)
And One Type Of Aldalia (D1).The Second Group Included Tow Sup Group Variation
