قُيمت في هذا البحث ستة طرز بيئية من شجيرات الوردة الشامية المنتشرة في سورية و المزروعـة في كلية الزراعة بجامعة دمشق. لوحظ وجود تباين كبير بين تلك الطرز في صفاتها الإنتاجية؛ فقد تفـوق الطراز (مسرابا) من حيث عدد الأزهار الذي بلغ 4.182 زهرة/نبات و وزنها الرطب و الجاف، و من ثم فقد وصلت الإنتاجية إلى 2.112 غ/نبات، كما أوضحت النتائج تفوق الطراز (عرنة) من حيث نـسبة الزيـت التي بلغت 071.0 % و قد بينت نتائج التحليل النوعي للزيت الناتج من الطرز المدروسـة الـذي أُجـري بواسطة جهاز MS/GC في مختبرات جامعة سليمان دوميريل في مدينة إسبارتا التركية وجود المكونات التاليـة بتراكيـز مرتفعـة: جيرانيـول (28-31%) سـيترونيلول (26-30 %) نيـرول (12-14%) جيرماكرين-د (6-8%) نوناديكان (4-6 %) لينالول (1-3 %) و قد كُشفَ عن العديد من المركبـات ذات التراكيز المنخفضة مثل: إيكوزان، أوجينول، سيترال، هكساديكان، أوكسيد الورد، و قد أظهرت تلك النتائج تفوقاً نوعياً للطراز (المراح) في مواصفات زيته العطري.
Six Syrian landraces of Rosa damascena planted at the faculty of agriculture of Damascus University have been evaluated in this study. A big variation of yield was noticed among the landraces. The landrace called (Mesraba) was superior to others concerning yield which was (112.2 g/plant). On the other hand, (Erna) had got the highest content of oil (0.071%). Analysis of oil implemented in Suleyman Demirel University in Turkey (Isparta) identified the main components of oil such as: Geraniol (28-31%), Citronellol (26-30%), Nerol (12-14%), Germacrene-D (6-8%), Nonadecane (4-6%) and Linalool (1- 3%). Besides, many trace compounds were detected such as: Eicosane, Eugenol, Citral, Hexadecane and Rose oxide. The essential oil of (Almarah) had got the highest quality.

Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال الزراعة والهندسة الوراثية، حيث تقدم معلومات قيمة حول إنتاجية ومحتوى الزيت العطري لأصناف مختلفة من وردة دمشقية. ومع ذلك، يمكن توجيه بعض النقد البنّاء للدراسة. أولاً، لم يتم توضيح الظروف البيئية التي تم فيها زراعة هذه الأصناف بشكل كافٍ، مما قد يؤثر على نتائج الإنتاجية ومحتوى الزيت. ثانيًا، كان من الممكن أن تكون الدراسة أكثر شمولية إذا تضمنت تحليلاً اقتصاديًا لتكلفة الإنتاج والعائد المالي. أخيرًا، كان من المفيد تضمين مقارنة مع أصناف أخرى من مناطق مختلفة لتقديم صورة أكثر شمولية عن أداء هذه الأصناف في بيئات متنوعة.

The research aims to study the effect of five harvesting wed (vegetative growth, the
beginning of open inflorescences flowering, the beginning of flowering, full bloom, and
completeness of the vegetative growth at the beginning of the month of Sept
ember and that
of plants that have already cutted), some of the morphological and productivity indicators
for common thyme Thymus vulgaris L . Experiment was designed by the complete
randomized manner in three replicates. Statistical analysis was performed by Anova test
using Genestat and account teams less moral LSD at a significance level of 5%. Results
showed superiority date mower fifth morally on the rest of the dates in terms of index
number of branches (16.50 branch / plant), productivity of the wet weight (55.00 g / plant),
productivity of dry matter (27.08 g / plant), while the superiority of the date of the second
mowing morally the rest of the appointments in terms of the percentage of essential oils
(size / weight) (2.10%), also reached the top of the plant at the time of his high mowing
fourth (21.50 cm).
Highlights the importance of the results by identifying the optimal harvesting date to
get the most fresh and dry weight of material and the highest percentage of essential oil,
and the resulting economic return to the farmer healthy and beneficial to the consumer,
with the continued preservation of the existence of the plant and its tender.
This study aims to provide GC-FID and GC-MS analyses of the essential oil of dried aerial parts of Ecballium elaterium L. grown in Jordan and examining its cytotoxicity capacity. Methods: Essential oil was obtained by hydrodistillation using Clevenge
r apparatus. MTT assay method was used to investigate the plant's in vitro antiproliferative activity against MCF-7, Caco-2 and Panc-1 cancer cell lines in addition to normal fibroblast cells. Results: E. elaterium hydrodistilled oil yielded thirty one components, accounting for 76.3% of the total oil content. High contents of nonterpenoidal compounds, sesquiterpenes, and monoterpene characterized the volatile fractions with hinesol (17.2%), the principal compound, benzaldehyde (12.3%) and E-β-ionone (7.8%) as the major constituents. E. elaterium ethanolic extract showed good activity against MCF-7 and Caco-2 cells (IC50 values=29.67 μg/mL and 17.64 μg/mL, respectively). Moreover, all extracts were safe on normal human cells. In conclusion: Evaluation of E. elaterium volatile oil has been conducted for the first time in Jordan; also various extracts were tested for the first time against Panc-1 cells. Furthermore, based on the obtained results, ethanol extract of E. elaterium may be advocated as candidate for breast and colorectal cancers management.
In October 2014, the collected air-green samples of Basil herb were gathered from the region of MashtaAlhulu in the ,Then the volatile oil from fresh samples was extracted with N-Hexane and other samples with steam distilled water, and we have found
the percentage of the volatile oil in the first sample (N-Hexane) is 2,7% , and 2,5% in the second sample (steam distilled water). Suitable conditions were chosen to separate the components of the volatile oil by GC-MS and we noticed : - the first sample (extracted with N-hexane) contain 18 compounds, and they are: Six Terpenes compounds and they form 21.22%,Hydrocarbon compounds form 21.8% from the total weight and they are 7 compounds, and one compound from Ketone class dicycle and its percentage is 2.32%,and two Ester compound and they form 18.96%, One phenolic compound and forms 21.60%, one Ether compound and forms 14.08%. -the volatile oil from the second sample (extracted with steam distilled water) contains 11 compounds, and they are: 6 compounds belong to Hydrocarbon class and they are the main components in the volatile oil with a 91.24% of the oil total weight, One compoundfrom Ether class forms 1.62%, one phenolic compound which forms 3.93%, and three Terpenes compounds and they form 3.17%.
A study was conducted to evaluate the diversity among chickpeas accessions
collected from Jordan for some morpho-agronomic traits, specially yield and its
components. The evaluated material consisted of 137 accessions and three
improved cultivars
released in Jordan. The study was conducted at the Jordan
University of Science and Technology Research Station using the augmented
design. Some of the parameters used in the evaluation included the mean,
standard deviation, range, coefficient of variation, diversity index. Also, a
dendrogram to establish the relationship among locations where landraces
were originally developed.
Results indicated the presence of significant variability for all traits under
investigation. Diversity index values (H′) exceeded 0.50 for all characters with
the highest value for biological yield (0.84), followed by lowest pod height
(0.82), grain yield (0.78), and straw yield (0.78).
The following accessions were found to be superior over the improved
cultivars in one or more of the studied characters: ILC 6941, ILC 6938, ILC
4411, and ILC 4096. These are important genetic resources for breeders to
improve the chickpea crop.
The results indicated the importance of the local landraces as a source of
genetic variability that should be conserved, evaluated and utilized by breeders
to improve the crop productivity and quality.
This research was carried out to determine the quantity of essential oil extracted
from myrtle Myrtus communis L leaves, by hydro distillation, and to identify the
major and minor components, besides to determine its quantities in the essential oil
by Gas Chromatography-Mass Spectrometry GC-MS. The samples were collected
on November 2013 from eight different climatic locations (Aleppo, Zarzour, Alzenea,
Katra AL-Rayhan, Al- Rayhana, Kasab, Mashta al-Holou and Mosiaf). The
quantity and composition of the essential oil were estimated on the basis of the
leaves dry weight. Oil quantity varied between the studied genotypes from different
locations, which range from 0.46 to 0.55 ml, with non-significant differences.
Eighteen compounds were identified in myrtle essential oil, and there were
significant differences in 13 compounds. 1,8-Cineole performed the highest rate
(18.85%) compared with other components, followed by α-Pinene (16.93%). While
the lowest percentage was (0.31%) of Myrcene. The
