نفذت تجربة في كلية الزراعة -جامعة تشرين في موسم النمو 2014-2015 بهدف دراسة تراكيز متزايدة من كل من ملح كلوريد الصوديوم (20, 15, 10, 0) dsm-1 و هرمون حامض الجبريلليك (100, 75, 25, 0) مغ/ل و التداخل بينهما على إنتاجية الطراز الوراثي من القمح (شام10), نفذت التجربة باستخدام التصميم العشوائي الكامل كتجربة عاملية بعاملين هما كلوريد الصوديوم و حامض الجبريلليك و بثلاثة مكررات 3x4x4)) و قد تم تحليل النتائج إحصائيا و قورنت المتوسطات باستعمال أقل فرق معنوي عند مستوى المعنوية 0,05. بينت النتائج إن زيادة تركيز كلوريد الصوديوم في وسط النمو أدى إلى انخفاض معنوي في مكونات الغلة و هي المحصول البيولوجي و طول السنبلة و عدد السنيبلات/سنبلة و عدد الحبوب/سنبلة و وزن 1000حبة و إنتاجية الحبوب/أصيص. كما أشارت النتائج إلى وجود زيادة معنوية في جميع قيم معدلات مكونات الغلة السابقة الذكر نتيجة الرش بحامض الجبريلليك و خاصة بالمعاملة 75)) مغ/ل, أما تأثير التداخل بين تراكيز كلوريد الصوديوم و حامض الجبريلليك فقد بينت النتائج أن رش النباتات بحامض الجبريلليك أدى إلى انخفاض معنوي للآثار السلبية الناتجة من التراكيز العالية لكلوريد الصوديوم في جميع مكونات الغلة للصنف شام10.
At Tishreen University in the Faculty of Agriculture a study was performed during the year(2014-2015),The experiment aimd to demonstrate the effect of increasing concentrations of both sodium chloride(0,10,15,20 dsm-1) and gibberellic acid(0,25,75,100 mg/l) and their interaction on some yield components of weat (SHAM10).The experiment was designed as Completely Randomized Design(CRD)by three replicates(3x4x4).Data were statistically analyzed to find out the least significal differences (LSD)between treatment at(0,05)level.Results indicated that increasing of sodium chloride concentration caused significant decreases in yield components(biological yield,spikelength,numberofspikelets/spike,number of grains/spike,weight of1000 grain and grains yield/pot.The treatment with GA3 acid especially (75)mg/l indicated significant increases in all averages of yield components.Results of interacions for both factors indicated that foliar aplication of GA3 acid counteracted that advers effects of high concentrations of sodium chlorde of yield components of the (SHAM10).

This experiment was conducted at the Faculty of Agriculture, Damascus
University (2001 – 2002), to assess the effect of radiostimulation of seeds of two
durum wheat varieties (Hourani and Cham 3) on some morphological traits
and yield components,
by using three doses of gamma rays (10, 15, and 20 GY).
The study showed significant differences among radiation doses. The high
doses (15, 20 GY) caused a significant deterioration in growth and development
of plants, as well as yield components of the two varieties.
This study was carried out during the growing season of 2015
to study effect od three planting date (1 Feb., 15 Feb. and 1
March) and four levels of nitrogen fertilization (0, 40, 60 and 80
kg/Ha) with interactive effect between them on some yield
components of cumin.
Five improved genotypes of durum wheat (T. turgidum var. durum) (Lahn,
Cham1, Gezira17, Bouhouth 5, and Acsad 65) were planted under the
conditions of the agricultural region (Bouka) of the Faculty of Agriculture-
Tishreen University during the ag
ricultural year 2002-2003, with a split-plot
arrangement to study the effects of flag leaf removal on grain yield and its
components.The genotypes differed significantly in flag leaf area, stomatal
frequency, yield parameters and protein content.
Flag leaf removal significantly reduced plant height, number of spikelets/
spike, number of grains/ spike, 1000 kernels weight and grain yield, while grain
protein content significantly increased.
There was a positive correlation between the flag leaf area and 1000-
kernels weight and grain yield, but protein content was negatively correlated
with grain yield.
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 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.
