This study has been carried out using the onion and pepper seeds to determine the effects of the aqueous medium temperature, during treatment with oxygen, on the germination percentage seed vigor and for determining the period needed for the treatment with the oxygen as well. The treatment period has taken ١٢-٣٦ hours according to the kind of crop and the medium temperature, which varied between ١٠-٣٠ °C. Results of the study indicated that the treatment of seeds with oxygen, in an aqueous medium, improved the germination percentage and the seed vigor. The period needed for the treatment of the seeds with oxygen differs according to the kind of crop and the temperature of the medium and varies between ١٨-٢٤ hours with respect to the onion seeds, and between ٢٤-٣٦ hours regarding the pepper seeds. The period needed for treatment with oxygen decreases with the rise of temperature.

Research summary
أجريت الدراسة على بذور البصل والفليفلة لتحديد تأثير درجة حرارة الوسط المائي أثناء المعاملة بالأكسجين على نسبة الإنبات وقوة البذور، وكذلك لتحديد الفترة اللازمة للمعاملة. تراوحت فترة المعاملة بين 12 و36 ساعة تبعًا لنوع المحصول ودرجة حرارة الوسط التي تراوحت بين 10 و30 درجة مئوية. أظهرت النتائج أن معاملة البذور بالأكسجين في وسط مائي أدت إلى تحسين نسبة الإنبات وقوة البذور، وأن الفترة اللازمة للمعاملة تختلف تبعًا لنوع المحصول ودرجة حرارة الوسط. كانت الفترة اللازمة للمعاملة تتراوح بين 18 و24 ساعة لبذور البصل وبين 24 و36 ساعة لبذور الفليفلة. كما بينت النتائج أن الفترة اللازمة للمعاملة بالأكسجين من أجل تحسين نسبة الإنبات تقل بارتفاع درجة الحرارة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة لأنها تسلط الضوء على تأثير درجة الحرارة ومعاملة البذور بالأكسجين على نسبة الإنبات وقوة البذور، وهي عوامل حيوية في تحسين الإنتاج الزراعي. ومع ذلك، كان من الممكن أن تكون الدراسة أكثر شمولية إذا تضمنت أنواعًا أخرى من المحاصيل لاختبار تأثيرات مماثلة. كما أن الدراسة لم تتناول بشكل كافٍ تأثيرات المعاملة بالأكسجين على المدى الطويل على نمو النباتات وإنتاجيتها. كان من الممكن أيضًا أن تكون الدراسة أكثر فائدة إذا تضمنت تحليلًا اقتصاديًا لتكاليف وفوائد استخدام هذه التقنية في الزراعة التجارية.
Questions related to the research
  1. ما هي الفترة اللازمة لمعاملة بذور البصل بالأكسجين عند درجة حرارة 20 درجة مئوية؟

    الفترة اللازمة لمعاملة بذور البصل بالأكسجين عند درجة حرارة 20 درجة مئوية هي 18 ساعة.

  2. كيف تؤثر درجة حرارة الوسط المائي على الفترة اللازمة لمعاملة بذور الفليفلة بالأكسجين؟

    تؤدي زيادة درجة حرارة الوسط المائي إلى تقليل الفترة اللازمة لمعاملة بذور الفليفلة بالأكسجين. فعند درجة حرارة 20 درجة مئوية، تحتاج المعاملة إلى 36 ساعة، بينما تقل الفترة إلى 24 ساعة عند درجة حرارة 30 درجة مئوية.

  3. ما هو تأثير معاملة البذور بالأكسجين على نسبة الإنبات؟

    أدت معاملة البذور بالأكسجين في وسط مائي إلى تحسين نسبة الإنبات وقوة البذور بشكل ملحوظ مقارنة بالبذور غير المعاملة.

  4. هل تختلف الفترة اللازمة لمعاملة بذور البصل والفليفلة بالأكسجين؟

    نعم، تختلف الفترة اللازمة لمعاملة بذور البصل والفليفلة بالأكسجين. لبذور البصل، تتراوح الفترة بين 18 و24 ساعة، بينما لبذور الفليفلة تتراوح بين 24 و36 ساعة.

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.
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 .

The aim of this research is to determine the best date and culture medium for the production of big rolls consisting of seed mixture (Lolium perenne, Festuca Arundinacea, Festuca rubra, Poa partensis) with the lowest costs. Seven different mediums were experimented in two different culture dates (15 September and 1 April). The results showed that the mediums consisting of turf or spent mushrooms compost gave the best germination rate (78-84%) in the two culture dates. They also gave ready big rolls in a period of time less than in the other mediums (78-102 days). The mediums also gave the best quality of big rolls in terms of light weight (41.96- 53.89 kg/m2), coverage rate (93-98%), and color. The medium that consisted of spent mushroom compost achieved an economic increase higher than that in the other mediums, where the coefficient of profitability in the former was (194.4%).
This study was conducted to evaluate the effect of pepper (pipiemento variety), and eggplant (Dara variety) seed's treatment on germination characteristics, and the impact of eggplant seeds treatment on seedling quality. The seeds were treated for 24 hours in glass containers, in which the ratio of seeds to the applied media was 1:5, the concentration of the mineral solution was 0.1%, while the concentration of each of GA3 and the organic nutrient solution was 0.01%. The media were continuously aerated by passing a current of pure oxygen (O2), at sufficient pressure to homogenously mix the seeds in the media. The seeds were dried up after 24 hours of treatment to remove the excess moisture. Seeds were germinated in Petri dishes, and soil-full containers to assess the germinability, and seed vigor. The eggplant seeds were also sown in peat-moss containing pots (8 cm indiameter) to study the influence of treatment on seedling quality. The results showed that treatment efficiency depends on the nature of the used media, and crop. In addition, it has been revealed that the aeration of media enhanced the germination, accelerated the seedling growth, and improved their quality.
