The study was carried out on trifoliate orange rootstock trees (Poncirus trifoliata L.) at Ciano Research Station where the trees were sprayed with nutrients or gibberelic acid GA3 or togethers, beside the control (without spraying). Different treatments of seed storage were tested in order to study their effect on seed viability to increase it. The seeds were stored for three months using four treatments: (a) seed storage in fruits at +4˚C, (b) Storage in juice at +4˚C, (c) Storage at lab temperature, and (d) seed storage at fridge temperature +4˚C. The results showed that all spraying treatments were positive at postharvest, as compared with the control. However, treatment of seed storage inside the fruit gave the highest significant germination rate for all spraying treatments. Treatments of spraying with nutrients were the best. The viability of seeds considerably decreased for all treatments of seed storage at fridge temperature +4˚C, whereas germination was zero for seed stored in juice and seed stored at lab temperature.

Research summary
تتناول الدراسة تأثير طرق التخزين والرش ببعض العناصر الغذائية وحمض الجبريليك على حيوية بذور البرتقال ثلاثي الأوراق (Poncirus trifoliata L.). أُجريت التجارب في محطة بحوث سيانو، حيث تم رش الأشجار بالعناصر الغذائية أو حمض الجبريليك أو كليهما، بالإضافة إلى الشاهد (بدون رش). تم اختبار أربع طرق لتخزين البذور لمدة ثلاثة أشهر: تخزين البذور في الثمار عند درجة حرارة 4 مئوية، تخزين البذور في العصير عند نفس الدرجة، تخزين البذور في درجة حرارة المختبر، وتخزين البذور في الثلاجة عند 4 مئوية. أظهرت النتائج أن جميع معاملات الرش أعطت نتائج إيجابية عند الزراعة بعد الجني مباشرة مقارنة بالشاهد. كانت معاملة تخزين البذور داخل الثمار هي الأفضل من حيث نسبة الإنبات لجميع معاملات الرش. بينما تراجعت حيوية البذور بشكل كبير عند تخزينها في الثلاجة عند 4 مئوية، ولم تنبت البذور المخزنة في العصير أو في درجة حرارة المختبر. توصي الدراسة بتجنب استخراج البذور من الثمار حتى موعد زراعتها في المشتل وتخزينها في الثمار عند درجة حرارة 4 مئوية لزيادة حيويتها.
Critical review
تعتبر هذه الدراسة مهمة لأنها تقدم معلومات قيمة حول كيفية تحسين حيوية بذور البرتقال ثلاثي الأوراق، وهو أمر حيوي لزراعة الحمضيات. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، الدراسة لم تشرح بشكل كافٍ الأسباب العلمية وراء عدم إنبات البذور المخزنة في العصير، مما يترك فجوة في الفهم العلمي. ثانياً، كان من الممكن توسيع نطاق الدراسة ليشمل أنواع أخرى من الحمضيات لتعميم النتائج. ثالثاً، لم تتناول الدراسة تأثير العوامل البيئية الأخرى مثل الرطوبة والضوء على حيوية البذور، مما قد يكون له تأثير كبير. وأخيراً، كان من الممكن استخدام تقنيات تحليلية أكثر تقدماً لتحليل البيانات بشكل أعمق.
Questions related to the research
  1. ما هي أفضل طريقة لتخزين بذور البرتقال ثلاثي الأوراق وفقاً للدراسة؟

    أفضل طريقة لتخزين بذور البرتقال ثلاثي الأوراق هي تخزينها داخل الثمار عند درجة حرارة 4 مئوية، حيث أعطت أعلى نسبة إنبات.

  2. ما هو تأثير الرش بالعناصر الغذائية وحمض الجبريليك على حيوية البذور؟

    الرش بالعناصر الغذائية وحمض الجبريليك أعطى نتائج إيجابية على حيوية البذور عند الزراعة بعد الجني مباشرة، مقارنة بمعاملة الشاهد.

  3. لماذا لم تنبت البذور المخزنة في العصير أو في درجة حرارة المختبر؟

    لم تنبت البذور المخزنة في العصير أو في درجة حرارة المختبر بسبب فقدانها نسبة كبيرة من رطوبتها خلال فترة التخزين، مما أدى إلى تراجع حيويتها.

  4. ما هي التوصيات التي قدمتها الدراسة لتحسين حيوية بذور البرتقال ثلاثي الأوراق؟

    توصي الدراسة بتجنب استخراج البذور من الثمار حتى موعد زراعتها في المشتل وتخزينها في الثمار عند درجة حرارة 4 مئوية لزيادة حيويتها.

Sour orange (Citrus aurantium L.) seedlings were sprayed three times a season with four levels of urea (45 % N) (2.5, 5.0, 7.5 and 10.0 g/L) and two levels of ascorbic acid (150 and 300 g/L), each alone or in combinations. Meanwhile the seedlings of control treatment sprayed with distilled water during 2010 growing season, twenty days intervals between each spray and another. Results obtained at the middle of October of the same season, indicated that the foliar spray with urea at the concentrations of 5.0, 7.5 and 10.0 g/L significantly increased leaves N and chlorophyll concentrations, leaves number, seedling leaves area, seedlings height, main stem diameter and leaves fresh and dry weight, especially at the foliar spray with 10.0 g/L. The means of these parameters were 3.19%, 66.80 SPAD, 146.66 leaves/seedling, 3700.00 Cm², 83.66 Cm, 4.50 mm, 4.70 g, 1.53 g, respectively. Meanwhile ascorbic acid spray at two concentrations unsignificantly affected all parameters, except leaves chlorophyll content, leaves number and seedling leaves area. Most treatments of combinations spray with urea and ascorbic acid significantly affected all studied parameters, especially the treatment of foliar spray of urea and ascorbic acid at a concentration of 10.0 g/L and 300 mg/ L, which gave the highest means of leaves N concentration, leaves number, seedling leaves area and leaves fresh and dry weights, and it unsignificantly differs from the treatments which gave the highest means of seedlings height, main stem diameter and percentage of leaves dry matter weight .
This research was conducted during 2010-2011 growing seasons on 15 years old trees of “Washington Navel” variety grafted on Citrus aurantium (sour orange) stock and planted in the village of “Al-hinnady” in Lattakia. To determine the appropriate pr eharvest and post-harvest treatments to get the most production and better quality of fruits.
The experiment was conducted during the two seasons (2015 , 2016 ) on the Lemon trees cv (Meyer ) aiming at studying the effect of the foliar spraying with the nutrients ( boron , zinc and iron ) on physical and chemical properties of the fruits Th ese nutrients were sprayed separately or as a mixture . The average of each of the physical properties of the fruit (length , width , firmness, volume and weight of the fruit ) , in addition to rind thickness and the fruits ` juice volume, ,the chemical properties of the fruit juice (total soluble solids, total sugars, total acidity, vitamin C) were studied. An increase was observed in all the studied parameters in the sprayed treatments compared to the control from( 6.37%- 3.33% -0.37% - 34.57mg%)to(9.33% -4.88% -1.89% -43.5%) in the first season and( 9.75% 5.87- 3.32% - 45%) in the second season, respectively. As a result of the statistical analysis, there were significant differences between all the studied treatments and the control with overpass of the treatment of the three elements (iron chelate + boron oxide + zinc chelate ) of all treatments in the most of the studied figures in both seasons. Statistical analysis of the fruit rind thickness showed the absence of the significant differences among the studied treatments.
Vitamin C concentration was studied in samples of infant formula from 5 companies (referenced A-E) using the 2,6-Dichlorophenolindophenol titration (AOAC, 2006) method. Results revealed that ascorbic acid content in formulas D and C was the closest to its recommended daily intake (RDI) and to the concentrations which are mentioned on the label of the samples. Storage conditions at room temperature or in the refrigerator did not affect ascorbic acid levels. In comparison to vitamin C concentrations in milk dissolved in tap water, its levels decreased when water was warm (40°C) or hot (100°C), and its concentrations further declined in dissolved form kept for two hours after preparation.
The research was conducted in plastic green house for the 2013-2014, in Alqangerh village, about 5 Km from the city of latakia, in order to study the effect of spraying the leaves with some humic compounds and amino acids on growth and production o f hybrids of cucumber (Novo,Dorruk). Spraying leaves with three organic fertilizers are (Huzone, Mol mixs), and two boats Dbalin and Amino vega (an amino acid). The results showed that all treatments of leaves spraying with organic fertilizer geve better resultus with significant differences than the control treatment in all the studied traits of both hybrids: (stem length, number of branches/plant, number of leaves/plant, leave area cm2, the number of flowers on the stem, number of fruits on the stem, number of floral branches, number of fruits on the branches).The treatment of spraying achieved with mixture of humic compounds and amino acids increase with significant differences in both the number of leaves/plant, number of branches/plant, the plant's stem length and number of fruit on the stem in the hybrid Novo. while the treatment of spraying achieved of hiozon increase with significant differences the number of branches/plant, the number flowers on the branches and number of fruits on the branches was in the hybrid Dorok. As for the early production and total production, the treatment of spraying with mixture of humic compounds and amino acids with significant differences on other transaction when both hybrids Novo and Dorruk amounted, respectivety (5 ، 4,1 kg/m2 ; 16 ، 14,8 kg/m2 ).
