يعد الماعز الشامي في سورية من الحيوانات الزراعية المحلية الهامة لما يملكه من مزايا ومواصفات تمكنه من الإنتاج والتناسل تحت الظروف البيئية القاسية لهذا فقد استخدم في برامج الخلط التربوي مع الماعز الجبلي كمعطي لمورثات صفة إنتاج الحليب الجيدة للحيوانات الخليطة
Random Amplified Polymorphic DNA (RAPD) was used to evaluate genetic
diversity among 11 Yemeny pomegranate types. Samples were collected in 2004
from three main regions: east, middle and north of the country (Rada, Hada
and Saada). PCR amplificati
on of pomogranate DNA with 30 random primers
generated 1013 bands, 118 of them were polymorphic 11.5%. Results showed
that the genetic diversity within the tested types was limited. Similarity values
ranged between 59 –96 % with a mean of 79 %. Statistical analysis showed
that the types can be divided into two clusters: cluster 1 with Orkobi and
Mellies types found in the Hada region; cluster 2 includes nine types belonging
to the Saada and Radaa regions .High similarity (90–96%) was obtained with
Khazemy, Liessy 1, Liessy 2, Taefi, Ahmer and Balady types. Whereas, some
types could be considerd as separate cultivars due to their high genetic
diversity such as, Orkoby and Mellies (Hada region) in addition to Bohssom,
Sommaty and Liessy 3 in the Saada region.
We continue in this work studying a new Algol (Arabic name) star, which we discovered during our survey on a field located at the edge of the Pleiades open cluster. We have observed this field in the period 2007 – 2010 with three different CCD-camera
s at the University Observatory Jena in Germany using three telescopes from 0.25 to 0.9 m. Our discovered star has an orbital period of days. The location of this star in the HRD is consistent with the age and distance of the already known Pleiades stars in this field. The derived spectral type of the primary star is G9 and K7 for the secondary one. Assuming that our star is a main-sequence star, the derived mass and radius are and for the primary, and for the secondary. refers to the primary star, where refers to the secondary star. is the solar mass, and is the solar radius.
This research was conducted during the 2009-2010 seasons in order to
inventory and locate the spread of wild olive in 17 locations in the province of
Hama. GIS and digital maps were used to characterize the sites of wild live
distribution geo- gra
phically, topography and the dominant vegetation. Results
showed highly environmental flexibility of Olive wild toward the sea level rise.
It was observed prevalence at high 185 m of sea level in Naora Shatha and
grading up to 994 m in the western side of Abu Qubeis protected area and more
prevalence at the wet and top wet bioatmosphere. Chemical and physical
analyses for soils of locations showed dominancy of the mud structure in most
locations which reach in some of them to 74% and this help in retaining soil
moisture. The vegetation prevalent in locations showed spreading of Oak trees
in addition to morphological varieties of wild Olives the sites studied with
different forms of degradation in most or all locations.
Ecological and morphological characterization and geographical distribution of caper plant, Capparis spinosa L. samples collected from various parts of Syria were investigated during 2010-2014. The antioxidant contents of caper samples were analyzed and the genetic diversity and genetic relationship among the samples were determined using the ISSR technique
