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.

Research summary
تهدف هذه الدراسة إلى تقييم تأثير بعض المعاملات التجريبية على إنبات بذور السرو الفضي (Cupressus Arizonica L.) لاستخدامها في مشاريع التحريج. تم الحصول على البذور من المخاريط الناضجة وإخضاعها لمعاملات مختلفة مثل النقع في حمض الستريك، حمض الكبريت، وهيدروكسيد الصوديوم، بالإضافة إلى معاملة الشاهد. أظهرت النتائج أن معاملة النقع بحمض الستريك بنسبة 0.1% مع تنضيد بارد لمدة 30 يوم عند درجة حرارة 4-5 مئوية أعطت أعلى نسبة إنبات بلغت 75%. بينما أعطت معاملة النقع بحمض الكبريت وهيدروكسيد الصوديوم نسب إنبات بلغت 60% لكل منهما. معاملة النقع بماء الصنبور أعطت نسبة إنبات 36%، وكانت نسبة الإنبات الأدنى في معاملة الشاهد التي بلغت 9%. كما تفوقت معاملة النقع بحمض الستريك في التأثير على ارتفاع النبات عند نهاية التجربة. توصي الدراسة باستخدام معاملة حمض الستريك في مشاريع التحريج نظرًا لفعاليتها وتكلفتها المنخفضة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة نحو تحسين إنبات بذور السرو الفضي، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، الدراسة لم تتناول تأثير المعاملات على المدى الطويل لنمو النباتات، مما يجعل من الصعب تقييم الفوائد البيئية والاقتصادية الكاملة لهذه المعاملات. ثانيًا، لم يتم التطرق إلى تأثير هذه المعاملات في ظروف بيئية مختلفة، مما قد يؤثر على نتائج الإنبات والنمو. ثالثًا، كان من الممكن توسيع نطاق الدراسة لتشمل أنواع أخرى من المعاملات الكيميائية أو البيولوجية لتحسين نسبة الإنبات. وأخيرًا، كان من الأفضل تضمين تحليل اقتصادي لتكلفة هذه المعاملات مقارنة بالفوائد المحتملة، مما يساعد في اتخاذ قرارات مستنيرة في مشاريع التحريج.
Questions related to the research
  1. ما هي أعلى نسبة إنبات تم تحقيقها في الدراسة؟

The effect of salinity and the treatment with fungicide on seed germination of Cupressus sempervirens L. was investigated. Five concentrations of salinity (0, 0.5, 1, 5 and 10%) were used. One part of the seeds was treated with fungicides (Benomyl ), while the other part was germinated without fungicide treatment. The results showed that seed germination was reduced by salinity, but the reduction was more pronounced without fungicide and with salt concentration, the seeds didn't germinate at 5 and 10% NaCl. Despite the decrease of germination indices with the increase of salt concentrations, the statistical results didn't show significant differences in salinity concentrations and the control in germination speed without fungicide, but they were significant with the fungicide. The statistical results showed significant differences between the presence and absence of fungicide in all treatments
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).
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 strati fication 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.
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 investigation was done to study the effect of spray for two times with CaCl2 0.5% and 1%, high potassium fertilizer and dipping with 2% CaCl2, in addition to packaging with polyethylene films on the storability of pear fruits "Coscia C.V". Th e results showed the significant superiority of high potassium fertilizer treatment on the other treatments concerning total and single sugars after harvesting time, while there weren't significant differences between the other treatments concerning the remaining indicators. After four months of storage, the packaging treatments were able to the significantly reduction of weight loss, in addition to preserving the firmness and total soluble solids in the comparison with unpackaged ones, the average of weight loss in unpackaged treatments was 15% and 0.65% in packaging treatments, which led to stop the storage of unpackaged treatments and continue packaging treatments until 7 months. After 7 months, the results showed that the dipping with 2% CaCl2 revealed the high weight loss, while was the least with high potassium fertilizer treatment, on the other hand there were no significant differences between treatments for firmness, total soluble solids and tetra table acidity, while total and single sugars showed significant differences between treatments. Moreover, the sensory tests assured the importance of packaging with CaCl2 treatments to improve storability and quality of pear fruits, which CaCl2 1% packaging treatment got the highest values for most of sensory tests.
