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

Research summary
تتناول هذه الدراسة تأثير الملوحة والمعاملة بالمبيدات الفطرية على إنبات بذور السرو دائم الإخضرار (Cupressus sempervirens L.). تم استخدام خمسة تراكيز من الملوحة (0، 0.5، 1، 5، و10%)، وتم تقسيم البذور إلى مجموعتين: الأولى معاملة بمبيد الفطريات (البينوميل)، والثانية غير معاملة. أظهرت النتائج أن الملوحة تؤثر سلباً على إنبات البذور، وكان التأثير أكثر وضوحاً في البذور غير المعاملة بالمبيد الفطري. لم تنبت البذور عند تراكيز 5% و10% من NaCl. رغم انخفاض مؤشرات الإنبات مع زيادة تركيز الملح، إلا أن النتائج الإحصائية لم تظهر فروقاً معنوية بين التراكيز الملحية والشاهد في سرعة الإنبات دون مبيد فطري، لكنها كانت معنوية بوجود المبيد. كما أظهرت النتائج فروقاً معنوية بين وجود المبيد وعدمه في جميع المعاملات. توصلت الدراسة إلى أن المبيد الفطري يحسن من نسبة الإنبات ويقلل من الزمن اللازم للإنبات، بينما تؤدي الملوحة العالية إلى تثبيط الإنبات بشكل كبير.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة لفهم تأثير الملوحة والمبيدات الفطرية على إنبات بذور السرو دائم الإخضرار، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل توسيع نطاق التراكيز الملحية لتشمل تراكيز بين 1% و5% لمعرفة تأثيرات الملوحة بشكل أدق. ثانياً، لم يتم التطرق إلى تأثير الملوحة على مراحل النمو اللاحقة بعد الإنبات، مما يحد من فهمنا الكامل لتأثير الملوحة على النبات ككل. ثالثاً، كان من الممكن استخدام أنواع أخرى من المبيدات الفطرية لمقارنة فعاليتها مع البينوميل. وأخيراً، كان من المفيد تضمين تحليل اقتصادي لتكلفة استخدام المبيدات الفطرية مقابل الفوائد المحققة من تحسين نسبة الإنبات.
Questions related to the research
  1. ما هو تأثير الملوحة على إنبات بذور السرو دائم الإخضرار؟

    تؤثر الملوحة سلباً على إنبات بذور السرو دائم الإخضرار، حيث تقلل من نسبة الإنبات وتؤخره، وتكون التأثيرات أكثر وضوحاً عند تراكيز الملح العالية (5% و10%) حيث لم تنبت البذور.

  2. ما هو دور المبيد الفطري في تحسين إنبات البذور؟

    يساعد المبيد الفطري (البينوميل) في تحسين إنبات البذور من خلال القضاء على الفطريات المرافقة للبذور، مما يزيد من نسبة الإنبات ويقلل من الزمن اللازم للإنبات.

  3. هل هناك فروق معنوية بين التراكيز الملحية المختلفة في سرعة الإنبات؟

    لم تظهر النتائج الإحصائية فروقاً معنوية بين التراكيز الملحية المختلفة والشاهد في سرعة الإنبات دون مبيد فطري، لكنها كانت معنوية بوجود المبيد الفطري.

  4. ما هي التوصيات المستقبلية التي قدمتها الدراسة؟

    أوصت الدراسة بمتابعة تأثير الملوحة بتراكيز 2% و3% لمعرفة مدى تأثير هذه الدرجات من الملوحة على إنبات بذور السرو دائم الإخضرار، ولتحديد الدرجة التي يتوقف عندها الإنبات.

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.
This study aims to investigate the abilities of two tree species (Pinus brutia and Cupressus sempervirens) planted in Banias Refinery Company to absorb and accumulate lead and zinc basically emitted by the Refinery. Samples of the planted species ( leaves, bark, and wood) and soil from around the plants were collected and analyzed by atomic absorption spectrophotometer. The results did not show significant pollution with these two elements. Moreover, there were not any significant differences between the two species in terms of the accumulation of Pb and Zn. While the Pb concentrations ranged between (24.96-30.84 ppm) for P. brutia and (24.05-30.23 ppm) for C. sempervirens, the Zn concentrations ranged between (34.99-82.99 ppm) for P. brutia, (18.11-59.86 ppm) for C. sempervirens. It was also revealed that P. brutia bark accumulated Pb more than the other parts, whereas C. sempervirens leaves accumulated Zn more than the other parts.
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 objective of this study is to compare the effect of five different Nacl concentration (0,50,100,150,200 mM) on seeds germination and seedling growth of two cultivars of soybean (sb-44,sb-172). Seeds were germinated in petri dishes with sterile filter paper moistened with 10 ml of test solution at 25 c˚ in dark . The obtained results showed that germination percentage , length of root and hypocotyl were decreased with the increase of the Nacl concentration in the medium. The best values was from cultivar sb-44 . After seven days of incubation , significant differences were observed between control and treated seeds . Germinated seeds were subcultured on basal Murashige and Skoog medium solid at the same Nacl concentration . The roots growth was mor affected by 200 mM Nacl compared to seedling growth . Plantlets were transfered into pots with nutrient soil , irrigated with saline water and were adapted at laboratory . we obtained good plants grew to maturity in 10- 12 weeks .
