Cultivars of Medicago Sativa l.var local were planted in three locations, ten pots per location. The first location wich is the most polluted one is (Bab Toma), second polluted one is (Jeser Victoria), and the reference location is (Daria), in the west of Damascus. Temperature, relative humidity and concentrations of main pollutants in that three locations were measured. Resultes showed that air pollution decreased growth of plants, amount of chlorophyll, production of plants, number of flowers, number of pods and leaf area in comparison with reference location.

Research summary
تدرس هذه الورقة تأثير تلوث الهواء على نبات البرسيم الحجازي (Medicago sativa l.var.local). قام الباحثون بزراعة أصناف من هذا النبات في ثلاثة مواقع مختلفة في دمشق: باب توما (الأكثر تلوثًا)، جسر فيكتوريا (متوسط التلوث)، وداريّا (المرجع الأقل تلوثًا). تم قياس درجة الحرارة، الرطوبة النسبية، وتركيزات الملوثات الرئيسية في هذه المواقع. أظهرت النتائج أن تلوث الهواء يقلل من نمو النباتات، كمية الكلوروفيل، إنتاج النباتات، عدد الأزهار، عدد القرون، ومساحة الأوراق مقارنة بالموقع المرجعي. تشير هذه النتائج إلى أن تلوث الهواء له تأثير سلبي كبير على نمو وإنتاجية نبات البرسيم الحجازي.
Critical review
دراسة نقدية: تقدم هذه الورقة بحثًا مهمًا حول تأثير تلوث الهواء على نمو وإنتاجية نبات البرسيم الحجازي، وهو موضوع ذو أهمية بيئية وزراعية كبيرة. ومع ذلك، يمكن تقديم بعض الملاحظات النقدية لتحسين الدراسة. أولاً، كان من الممكن أن تكون الدراسة أكثر شمولاً إذا تضمنت تحليلًا للتأثيرات طويلة الأمد لتلوث الهواء على النباتات، وليس فقط التأثيرات الفورية. ثانيًا، لم يتم ذكر أي تدابير محتملة للتخفيف من تأثيرات تلوث الهواء على النباتات، وهو جانب يمكن أن يكون مفيدًا للمزارعين وصناع القرار. أخيرًا، كان من الممكن أن تكون الدراسة أكثر قوة إذا تم تضمين مجموعة أوسع من المواقع ذات مستويات تلوث مختلفة للحصول على صورة أكثر شمولاً عن التأثيرات المحتملة لتلوث الهواء.
Questions related to the research
  1. ما هي المواقع الثلاثة التي تم اختيارها للدراسة؟

    المواقع الثلاثة هي باب توما (الأكثر تلوثًا)، جسر فيكتوريا (متوسط التلوث)، وداريّا (المرجع الأقل تلوثًا).

  2. ما هي التأثيرات الرئيسية لتلوث الهواء على نبات البرسيم الحجازي؟

    تلوث الهواء يقلل من نمو النباتات، كمية الكلوروفيل، إنتاج النباتات، عدد الأزهار، عدد القرون، ومساحة الأوراق.

  3. ما هي العوامل البيئية التي تم قياسها في الدراسة؟

    تم قياس درجة الحرارة، الرطوبة النسبية، وتركيزات الملوثات الرئيسية في المواقع الثلاثة.

  4. ما هي التوصيات التي يمكن تقديمها بناءً على نتائج هذه الدراسة؟

    يمكن التوصية بتقليل مستويات تلوث الهواء من خلال سياسات بيئية أكثر صرامة، واستخدام تقنيات زراعية تقلل من تأثيرات التلوث على النباتات.

The study assure heavy effect of harmful machines waste matter on leaves cell structure of some plants which grow at conditions of Damascus city, were cause to anormality of cell form and protoplasm degradation. Jasminum is less effected with pollutants than Citrus aurantium.
The influence of vesicular - arbuscular Mycorrhiza fungi (VAM) on symbiotic fixation of N٢ in alfalfa plants has been observed. Beneficial effects of VAM plants in saline soil are of great interest. The aim of this work was to study the effect of VAM or phosphorous fertilization on alfalfa (Medicago sativa L.) yields, number of nodules and N٢ fixation by N١٥ isotope dilution at different salinity levels.
The research was conducted to study the resistance of Nerium plant which are planting on sides of roads and the cities portals. The research was performed by studying the leaves of Nerium plant, through studying the length and weigh of the leaf, an d its area and water content. In addition to studying the wools and hiatus and chlorophyll concentration, and compared the results between the polluted region which is the entry of Banias City, and the control one which is the gardens of Tishreen University. Results showed non significant reduction in length, weight and area of the leaf in the polluted region compared with the control one. It attained (16.2 cm, 0.97 g and 26.3 cm2), respectively in the polluted region. Where it was (17.8 cm, 1.25 g and 27.7 cm2), for control region, respectively. Also, there was no significant differences in water content between the two studied regions. It attained respectively (52.2 and 53.9 %). Our results showed: - That a number of hiatus decreased, whereas the wools increased in the polluted region compared with control region insignificantly. The mean of a number of it was 12 in polluted region, compared with 14 in the control region. - A simple insignificant reduction in the concentration of chlorophyll A in polluted region compared with the control, where it attained (0.93 and 0.98), respectively. The Nerium oleander plant was resistance and tolerance to the air pollution.
The study development of diffusion flame has special importance in applications and industrial burners. For achieving this aim, a diffusion burner was manufactured from Steel metal and three models of bluffbodies were prepared with different engineering shapes: Diverge inside outside bluff-body, Rods bluff body, and Combined bluff-body. In addition, designing and building of integrated experimental system with group of control systems for supply fuel and air flow are described. On the other hand we prepared system of Schieren Photography and measured length of Diffusion Recirculation flame and obtained good results in field of reaction and diffusion through analyzing Schieren Photography for flame front. The obtained results (Hvorticity =54 mm and Wvorticity= 52.5 mm) result widened stability range of flame front. Effect of vorticity and diffusion was studied of soot free length fraction (SFLF) and considered as an important parameter in industrial applications for burners, leading to reductions in pollution and poisonous gas emission. The results (SFLF=0.2) are achieved for the first time in comparison to results of literature review.
This study has conducted to investigate the effect of air pollution on diagnostic elements and morphologicl characters of leaves of Neruim oleander Cultivated in roadsides in Lattakia City . Samples were collected from tow sites differ in pollution inteusity between october 2012 and september 2013 . The first site ( Al Jmhoria street in Lattakia city ) was more polluted and has more traffic activity . Whil the second site ( tishreen University park ) Was Less polluted and less traffic activity . The results have showed that the length , the weight and the colour of the leaf are negtively incieased because of traffic intensity and this , inturn , affects the shape , the size and the number of diagnostic elements which play animportant rule in differentation the species from each other .
