تمت مقارنة ستة أصناف من القمح القاسي من حيث النسبة المئوية للإنبات، و متوسط زمن الإنبات و استئناف الإنبات بعد الإجهاد؛ ضمن محتويات رطوبية مختلفة للتربة في المختبر. و قد كان لكلٍ ،MGT من رطوبة التربة و الصنف تأثيرات في الصفات المدروسة. سببت زيادة الإجهاد الرطوبي انخفاضًا معنويًا في النسبة المئوية للإنبات. كما وجد هناك اختلاف بين الأصناف من حيث الإنبات، إذ أظهر الصنفان حوراني 27 و شام 3 قدرة إنباتية أعلى وزمنًا أقصر للإنبات مقارنة بالصنفين بحوث 5 و شام 1، أما الصنفان لحن و سيناتور كابيللي فكانا في موقعٍ متوسطٍ بين الأصناف.
Six durum cultivars were compared in relation to germination percentage, mean germination time, and germination “Catch up” from stress under different soil moisture contents in the labs. Both soil moisture and cultivars have shown effects on the studied parameters. Increasing moisture tension had caused a significant reduction in the germination percentage. The cultivars differed in their germination. Haurani 27 and Cham3 showed a higher germination potential and their germination times were shorter than the two varieties Bohouth 5 and Cham1. The varieties Lahn and Senator Capelli were intermediate among the other examined cultivars.

This research was conducted to determine the most responsive phenological
stage for supplementary irrigation of the durum wheat in a primary stationary
region.
It consisted of six different water treatments in addition to control (non
irrigated)
:
1-From planting to seedling emergence; 2-From planting to tillering; 3-From
planting to booting; 4-From planting to flowering; 5-From planting to the end of
the milk stage; 6–Sowing irrigation and irrigation according to necessity
throughout the milk stage.
The study has been repeated in four blocks for three seasons from 2002 to
2005. The results of the first two seasons showed that the:
The treatment from planting to booting, was canceled because of the rain and
soil dampness during this growth period. A significant increase in production,
water use efficiency, and one 1000 kernel weight, of both 5th and 6th treatments was
noticed in comparison with other treatments and the control. Results of the three
seasons were varied due to the environmental variation in temperature and amount
of rainfall.
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 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 research was conducted at Tal Shnan village, located at the eastern of Homs
city, Syria during 2012/ 2013 growing season, using hard local wheat cultivar,
Sham 5, to study the effect of seed rates (120, 150, 180, 210 kg/ha), spray with
differ
ent parts of sorghum water extracts using different, and weeding on wheat
yield and weeds accompany with the crop.
This study was carried out at Karahta Station of Field Crop
Research, General Commission of Agricultural Scientific Researches
during 2010-2011 and 2011-2012 cropping seasons in order to determine the
phenotypic correlation coefficient between the traits and the path coefficients
analysis for the most affected traits in grain yield.
