This research was carried out during two seasons 2014 – 2015 to study effect of seed coats on germination of endocarp, seed and embryos of two wild genotypes (M1, M2) of Mahaleb rootstock (Prunus mahaleb L.) prevailing in Alhaffa area, Lattakia. The experiments were done at Lattakia Scientific Agricultural Research center and Faculty of Agriculture at Tishreen University. The Results of the seeds planted on agar 0.7% in dark at 15 C° showed that no germination of the M1 endocarp VS late and low germination at 10% for the M2 endocarp starting after 98 days. As for seeds, the germination was (66.66%) and (53.33%) for M1 and M2, respectively. Removal of the woody coat (endocarp) and seed coat makes the germination faster. the embryos germination was (80%) and (60%) for M1 and M2, respectively.

Research summary
أجري هذا البحث خلال موسمي 2014-2015 لدراسة تأثير الأغلفة في إنبات نوى وبذور وأجنة طرازين بريين (M1, M2) لأصل المحلب (Prunus mahaleb L) المنتشرة في محافظة اللاذقية/ منطقة الحفة. أجريت التجارب في مخابر مركز البحوث العلمية الزراعية باللاذقية وفي كلية الزراعة بجامعة تشرين. أظهرت النتائج أن نوى الطراز M1 لم تنبت، بينما بلغت نسبة إنبات نوى الطراز M2 (10%) بعد 98 يوماً. أما البذور فقد بلغت نسبة إنبات بذور الطراز M1 (66.66%) وبذور الطراز M2 (53.33%). كان لإزالة كل من الإثدوكارب والغلاف البذري الرقيق الأثر الإيجابي في تسريع إنبات الأجنة وتنشيط استجابتها للإنبات حيث وصلت نسبة إنبات الأجنة إلى (80%) في الطراز M1 وإلى (60%) في الطراز M2. تعتبر هذه النتائج مهمة لتحسين نسبة إنبات بذور المحلب وصعوبة إنتاج الغراس المستخدمة كأصول للتطعيم في المشائل.
Critical review
دراسة نقدية: على الرغم من أن الدراسة تقدم نتائج مهمة حول تأثير الأغلفة في إنبات بذور المحلب، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الممكن توسيع نطاق الدراسة لتشمل طرزاً أخرى من المحلب لمعرفة ما إذا كانت النتائج متسقة عبر مختلف الطرز. ثانياً، لم تذكر الدراسة تأثير العوامل البيئية الأخرى مثل الرطوبة والإضاءة على الإنبات، مما قد يؤثر على النتائج. ثالثاً، كان من الممكن تقديم توصيات أكثر تفصيلاً حول كيفية تطبيق النتائج في الزراعة العملية لتحسين إنتاجية المحلب. وأخيراً، كان من الممكن توضيح المزيد من التفاصيل حول الإجراءات التجريبية لضمان إمكانية تكرار الدراسة من قبل باحثين آخرين.

This research aims study the effect of different treatments in activate and increase percentage of germination Cupressus arizonicaL.seeds to use plants in forestation projects, seeds were get from mature conifers, and tested by different treatments with control, then cultured within polyethylene bags many times to calculate indicators of germination. The results showed that the soaking the seeds Cupressus arizonicaL. in citric acid 0.1% with cold wet stratification for 30 days at 4-5c gave higher germination percentage 75%.The treatments of the soaking seeds in sulfuric acid0.1% and hydroxide sodium 0.1% with cold wet stratification for 30 days gave respectively 60%-53% .But superiority was not significant. Other treatments; soaking the seeds in tap water 24h with cold wet stratification for 30 days gave only 36%.But the control treatment gave lower germination percentage of all just only 9%. The treatment of soaking seeds in citric acid 0.1% with cold wet stratification for 30 days surpassed the rest of the treatments in effect on plant height at the end of the experiment.
The study has been done in many farms which are producing sweet cherry in Lattakia during the season (2014-2015). This research focuses on study timing of phonological stages of sweet cherry in two regions (sluonfa , aen alhaeat) in Lattakia ciety and studies the effect of some climatological conditions like temperature and rain on this plant . The result of this study revealed clear variation in the climatological conditions between the two regions under study. T his variation in climatological conditions led to variation in the phonological stages of sweet cherry in two regions under study.
The effect of different treatments on carob seed germination was studied. The results showed that, seed scarification was the most effective method in increasing germination rate as well as the use of concentrated sulfuric acid for 30 minutes reac hing 100%, followed by the treatment with alcohol for 60 minutes, and immersing seeds in hot water for 60 minutes. The results also indicated that the speed of germination when seeds were scarified was the best (I.D.=14.5), followed by the treatment with concentrated sulfuric acid for 30 minutes (I.D.=21.5), alcohol for 60 minutes (I.D.= 38) and immersing seeds in hot water for 60 minutes (ID.=60).
This study was carried out in a protected area at Rangeland and Dry Environment Research Station, belongs to ACSAD and Aleppo university in the Muslumieh, Aleppo, during 2004, by cultivating 11 plant species belong to three different families, Fab aceae (3 species), Poaceae (7 species) and Rosaceae (one species), using 4 moisture Levels (5, 10, 15 and 20 mm), and 6 seeding depths (0, 1, 2, 3, 5 and 7 cm). Results showed that the seeds of all the investigated species failed to germinate at the moisture level of 5 mm, while Onobrychis sativa (36.2%), Agropyron elongatum (53.9%), Agropyron cristatum (36.1%), Phalaris tuberose (41.1%), Dactylis glomerata (12.2%) and Sanguisorba minor (1.12%) germinated under 10 mm humidity. The seeds of all investigated species germinated at the higher moisture levels (15 and 20 mm), but the germination ratio varied between the species. The seeds of all studied species were capable of germinating when placed at the soil surface and seeding depth of 3 cm. The seeds of Agropyron elongatum (73.3%), Agropyron cristatum (13.3%), Phalaris tuberosa (36.7%) were capable of germinating at depth of 5 cm. The seeds of all studied species failed to germinate at a the planting depth of 7 cm.
This cultivation was carried out in the farm of the Faculty of Agriculture at Damascus University during the 2013-2014 agricultural season to study the effect of seeding rate per unit area and planting dates on yield and its components for three barley genotypes under rain-fed conditions.
