نفذت تجربة حقلية في مزرعة أبي جرش بكلية الزراعة في جامعة دمشق خلال الموسمين الزراعيين 2011-2012 /2013-2014 بهدف تقييم أداء بعض الأصناف الزيتية المدخلة من محصول العصفر ( SON-4 , SON5 , PI133055 , الشاهد المحلي , GILA ) تحت تاثير الظروف البيئية السائدة في محافظة دمشق خلال العروة الربيعية والعروة الصيفية ( التكثيفية ) بعد حصاد محصول القمح ) وباستخدام معدلين من السماد الآزوتي ( الشاهد - دون إضافة السماد , ومعدل 75 و150 كغ . هكتار -1 وحدة نقية من الآزوت )
A field experiment was carried out at Abi Jarash farm, Faculty of Agriculture, Damascus University, during the two agricultural seasons 2011-2012/2013-2014 in order to evaluate the performance of some oily varieties introduced from the safflower crop (SON-4, SON5, PI133055, Local Witness, GILA) under the influence of environmental conditions. Prevalent in Damascus governorate during the spring and summer season (intensive) after harvesting the wheat crop) using two rates of nitrogen fertilizer (control - without adding fertilizer, and at a rate of 75 and 150 kg. ha - 1 pure nitrogen unit)

This search was carried out in the farm of faculty of Agriculture-
Damascus during 2012-2013 to determine the adaption of five
Safflower genotypes) Farming conditions in the lug
intensive in the province of Damascus under the effect of different
nitrogen fertilizers and witness without fertilization N3 . And how they affected safflower
accessions morphological traits and productivity.
The research was executed in Biotechnology Lab (Faculty of
Agriculture – Damascus University), during the season 2016.
Sixteen genotypes of Sunflower Oil were planted to study the
genetic diversity among these genotypes and to determine the
degree of genetic Agreement using the technique SSR (Simple
Sequence Repeats).
The research was carried out during 2011-2012 in order to study the effects of five
levels of fertilization (mineral fertilization N:65 P:65 K:70kg/h, and organic fertilization 5,
10 and 15ton/h), three spaces between rows (50, 75, and 100cm), one
15cm space between
one plant and another, and the interaction between them on the production of safflower dry
colored leavel, seed, and oil.
The study showed the following results: all the levels of the studied fertilization were
significantly superior in the production of dry colored leavel, seed and oil over the control.
However, there were no positive differences in the proportion of oil between the treatments
of fertilization and the control.
The 100cm farming space among rows led to a significant positive effect in the
production of safflower seeds, while the 50cm distance among farming rows in the
production of dry coloring leaves was superior over 100cm and 75cm distance. There were
no positive differences in the proportion of oil; while the mean of oil productivity came
down whenever the plant spacing increased from 50 to 75 and then 100cm.
The interaction between the levels of the studied fertilization and agricultural plant
spaces gave a positive significant effect in most studied characteristics. The most
significant positive effect was for the interaction between the mineral fertilization and
100cm distance, and then came the average of the organic fertilization 15ton/h and 100cm
space between rows.
The research was Carried out in Jisr area in the province of Idlib during the growing
season 2013 - 2014 to study the effect of planting dates in autumn sowing 28/9/2013 = (1),
8/10/2013 = (2), 18/10/2013 = (3) and spring sowing 18/3/2014 = (1), 28
/3/2014 = (2),
8/4/2014 = (3) on yield and growth parameters.
The results showed that the autumn sowing has a significant increase in growth
parameters compared to spring sowing: adapting coefficient (76.67-82.28%), Plant hight
(67.15 - 56.3 cm), number of branches/plant (11.63 - 6.84), number of head/Plant (21.39 -
17.76), oil content (23.19 - 20.68)%, yield petals (96.12 - 60.57) kg/ha, seed yield (1331.82
- 768.31) kg/ha, oil yields (315.15 - 158.99) kg/ha to autumn and spring, respectively.
While maturity date of autumn plants was delayed compared to spring (245.33 - 145.33)
Day.
When sowing was of autumn, growth parameters of third soing date were a
significantly higher compared to both the second and first sowing: number of branches /
plant, number of heads / plant, number of seeds / head, oil ratio (%), oil yield (kg/ha),
yields seeds ( kg/ha), petals yield (kg/ha). Wheras the first sowing date has delayed
maturity date compared of both the second and third sowing dates.
When sowing was in spring, growth parameters of the first sowing dates were a
significantly higher compared to both the second and third except for days to maturity.
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.
