A hydroponic culture experiment was conducted under the green house conditions, at the general commission of scientific agricultural research, and the faculty of agriculture, Damascus university, during the year 2002-003. The objectives of this investigation concentrated on the influence of four salinity levels (0-50-100-150 mM NaCl) on some physiological parameters of eight sorghum genotypes. The experiment was designed in a RCB design with three replications.

Research summary
أجريت تجربة زراعة مائية تحت ظروف البيت الزجاجي في الهيئة العامة للبحوث العلمية الزراعية وكلية الزراعة بجامعة دمشق خلال عام 2002-2003. ركزت أهداف هذه الدراسة على تأثير أربعة مستويات من الملوحة (0-50-100-150 ملي مولار NaCl) على بعض المعايير الفسيولوجية لثمانية أصناف من الذرة الرفيعة. صُممت التجربة بتصميم القطاعات العشوائية الكاملة بثلاث مكررات. أظهرت النتائج أن NaCl زاد من محتوى السكريات القابلة للذوبان في الإيثانول، والأحماض الأمينية الحرة، والبرولين في الأصناف المختبرة. وُجدت فروق معنوية بين الأصناف في المعايير المدروسة. أعطت الأصناف مثل LOCAL-29 وIZ-19 وIZ-14 أعلى محتوى من السكريات، في حين أعطت ICSV-115 وGIZA-123 أقل محتوى من السكريات. أعطت ICSV-115 أعلى محتوى من الأحماض الأمينية الحرة، بينما أظهرت الأصناف LOCAL-29 وIZ-19 أقل محتوى من الأحماض الأمينية الحرة. أعطت الأصناف IZ-18 وLOCAL-29 وIZ-19 وIZ-14 أعلى محتوى من البرولين، في حين أعطت ICSV-115 وG-123 أقل محتوى من البرولين. يمكن اعتبار المعايير الكيميائية الحيوية، وخاصة السكريات، كصفة رئيسية لتحمل الإجهاد الملحي في الذرة الرفيعة في مرحلة الشتلات.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة لفهم تأثير الملوحة على الذرة الرفيعة، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، لم يتم توضيح كيفية اختيار الأصناف الثمانية المستخدمة في الدراسة، مما قد يؤثر على تعميم النتائج. ثانياً، كان من الممكن تضمين مزيد من التفاصيل حول الظروف البيئية الأخرى التي قد تؤثر على النتائج، مثل درجة الحرارة والرطوبة. ثالثاً، كان من المفيد إجراء تجارب ميدانية بالإضافة إلى التجارب المائية للتحقق من النتائج في ظروف زراعية حقيقية. أخيراً، كان من الممكن استخدام تقنيات تحليلية أكثر تقدماً لقياس المعايير الفسيولوجية للحصول على نتائج أكثر دقة.

Heritability and genetic advance of some grain yield components and some morpho-physiological traits in 36 sorghum hybrids [Sorghum bicolor L. Moench] produced by top-cross using cytoplasmic male sterility were estimated. Narrow-sense heritabilit y for plant height and head length were relatively high in Damascus location (65% and 56%) respectively, but the narrow-sense heritability of all characters in Raqqa location were low, the range was from 3% for threshing percentage to 34% for plant height, and from 22% for seed weight/head to 60% for plant height in the combined analysis. Genetic advance estimates were relatively low for all characters, the range was from 0% for 100 seed weight to 28.3% for plant height (Damascus location), and from 0.02% for seed numbers/head to 15.2% for plant height (Raqqa location), and from 5.8% for the number of days to flowering to 26.5% for plant height (combined analysis). Some characters such as plant height and head length showed relatively high values of heritability, but exhibited low values of genetic advance. Therefore other characters had low heritability coupled with low values of genetic advance indicated predominance of non-additive gene action. This result implies the need for several generations of selection to improve grain yield components and other traits.
Ssilverleaf nightshade (Solanum elaeagnifolium Cav.) is a serious weed to cotton and other field summer crops due to the alkaloids present in the plant and have allelopathic potential on the germination of other plants. Sorghum (Sorghum bicolor) h ave been investigated as a allelopathic crop having strong competition potential in the field containing many numerous water solution allelochemicals and can be used to control weeds in field crops. A field competition study between sorghum and silverleaf nightshade plants was conducted to determine how long every plant can resist against the other.
Different experiments were conducted under laboratory conditions, at the Faculty of Agriculture – Damascus University, in order to develop a suitable and efficient screening tool, which can be applied to assess the genetic variability among 20 sor ghum genotypes (Izraa series) for high salt stress tolerance. We were able to develop a screening technique involves pre- exposing sorghum seedlings to a sub – lethal level of salinity stress (induction stress) (150 mM NaCl) for 16 hrs which can induce the genotypes to prepare defensive means, which may differ according to the genetic potentiality of each genotype. These protective responses may help the genotype to endure the lethal level of salinity stress (400 mM NaCl) for 48 hrs. At a later stage, the seedlings were transferred to distilled water for 72 hrs and the rate of recovery growth was taken as a criterion to select the highly salt tolerant genotypes by using Zdistribution analysis. Results revealed that genotypes such as: Izraa 10, Izraa 15, and Izraa 18 could be classified as salt tolerant genotypes which showed higher recovery growth and the least growth reduction over the control. Whereas a genotype such as Izraa 22 was grouped as salt sensitive one where the percent growth reduction over the control was greater, indicating that this genotype has low recovery growth ability. Our results suggest that the proposed screening technique is rapid, effective, and match the natural screening.
An experiment was conducted in Kharabo station which belongs to the faculty of agriculture, Damascus university during the growing season 2009 ! 2010, to evaluate the response of seventeen sorghum genotypes under water stress conditions during the flowering stage according to the randomized complete block design (RCBD), with three replicates.
The research was carried out in Nawa area in Daraa governorate during the year 2012, to study the response of four sesame genotypes (Local Idleb, Zouri, Improved Hourani and Brown Sudani) to four irrigation treatments (rainfed cultivation, one sup plemental irrigation during branches formation, two supplemental irrigations during branche and capsules formation and three supplemental irrigations during branches formation, capsules formation and seed filling stages). The experiment was laid out in split plot design with three replications. The statistical analysis clearly indicated to the existence of genetic variation in (p < 0.05) the response of the studied sesame genotypes to applied irrigation treatments. The genotype Local Idleb recorded significantly the highest values of all investigated traits and the heighest seed yield (3.45 t. ha-1) as compared to other studied genotypes. Providing sesame crop with three irrigations surpassed in all investigated traits and recorded the highest seed yield (3.79 t.ha-1). It was recommended to provide sesame crop with three irrigations during critical stages (branches formation, capsules formation and seed filling).
