The results shows that, the cold wet of Canary pine seeds stratification for 15 days at (4-5c◦),gave higher germination percentage( 91.11%). The treatment of soaking seeds with superiority was not significant. Other treatments; the cold wet stratification of seed for(30) days at(4-5c◦), soaking seeds with tap water for (48 h.) and the control, all gave lower germination percentages, but still higher than (60%). The treatment of soaking seeds with GA had significant superiority in the speed of germination (2.32 day ∕ seed), but it was not significant with the cold wet stratification.

Research summary
تناولت الدراسة تأثير بعض المعاملات في تحسين نسبة إنبات بذور الصنوبر الكناري (Pinus canariensis). أظهرت النتائج أن التتضيد البارد الرطب لمدة 15 يوماً عند درجة حرارة 4-5 م° أعطى أعلى نسبة إنبات بلغت 91.11%، تلاه النقع بحمض الجبرليك بتركيز 300 جزء بالمليون لمدة 20 دقيقة بنسبة إنبات 82.22%. لم تكن الفروق معنوية بينهما، بينما أعطت المعاملات الأخرى نسب إنبات أقل ولكنها أعلى من 60%. تفوقت معاملة النقع بحمض الجبرليك في سرعة الإنبات (2.32 يوماً/بذرة) وفي درجة التجانس (4.39 بذرة/يوم) على معاملة النقع بماء الصنبور والشاهد، ولم تتفوق معنوياً على معاملة التنضيد البارد. توصي الدراسة باستخدام التتضيد البارد الرطب لمدة 15 يوماً كأفضل معاملة لتحفيز إنبات بذور الصنوبر الكناري، مع إمكانية استخدام النقع بحمض الجبرليك عند الحاجة لتسريع الإنبات.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال تحسين إنبات بذور الصنوبر الكناري، خاصة في ظل التحديات البيئية والتغيرات المناخية. ومع ذلك، كان من الأفضل تضمين المزيد من التفاصيل حول تأثيرات المعاملات المختلفة على النمو اللاحق للنباتات، وليس فقط على نسبة الإنبات. كما أن الدراسة لم تتناول تأثيرات المعاملات على مقاومة الأمراض والآفات، وهي عوامل مهمة في زراعة الأشجار. بالإضافة إلى ذلك، كان من الممكن توسيع نطاق الدراسة لتشمل أنواعاً أخرى من الصنوبر لمقارنة النتائج وتعميم الفوائد.

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 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 during 2014-2015 in two different nurseries located in University nursery (Lattakia governorate) and Salhab nursery (countryside of Hama governorate). Seeds were taken from two sites of Lattakia governorate (Mashqita– Bsn ada) where Cordia myxa exists as exotic species in some coastal regions and three treatments in addition to control were examined .The results showed that there is an effect of scarification of seeds on investigated treatments and were significant differences in germination percentage in both sites which recorded 55% in university nursery and 35% in Al-Ghab nursery. While there were not contrast between the soaking in boiling and tap water treatments on the seed germination energy in Al-Ghab nursery. Scarification treatment gave higher value of germination energy 25% in Al-Ghab nursery and 21.66% in university nursery , while the same treatment decreased germination velocity compared to other treatments in university nursery which seed needed in average ( 8,01 day) whereas the same treatment increased germination velocity in Al-Ghab nursery which needed (1,54 day). Finally, regarding to cutting ,There is not observe to any positive influence to cuttings which treated in ABA hormone (1g/l) for (10,20,30 m). It could be deduced that there were changes in germination percentage, germination energy and germination velocity in two sites which appeared to be a Preliminary indication of impact of the some dormancy breaking treatments on investigated indications of Cordia myxa Forsk. species .
This study was carried out at three different forest sites in Syria in order to determine the effect of changing rainfall, temperature and soil on kernel productivity of stone pine (Pinus pinea L.)> these sites included: Jabal Alnabi Mata, (Tartou s province, L1), Dahr Alkhoser (Homs province, L2) and E′en Jron site (Idleb province, L3). Results showed that kernel productivity of stone pine per tree was 236.3, 252.8, 143 g per tree, and 177, 162.3, and 86.98 kg per hectare in L1, L2, and L3, respectively. These differences were attributed due to the variation in the composition, textured and fertility of the soil available in the three locations studied. It was concluded that trees of stone pine grow better and superior in Kernel productivity in humid and super-humid bioclimatic zone.
The experiment was carried out to assess the germinability and seedling growth rate of some treated vegetable seeds (i.e. onion, carrot, and tomato) with aerated - aqueous solutions. Seeds were treated for 24 hours with 0.1% of both succinic acid and nutrient solution, and the seeds to medium ratio was 1:5. The soaking solution was continuously aerated by an air pump. At the end of treatment, the seeds were dried up at room temperature to eliminate the excess superficial moisture.
