The study was conducted at the growing season 2009 in one of an orchard in Abu-Al-Khaseeb region – Basrah, studied the effects of spraying of GA3 concentration of 25 mg. l-1 and spraying of liquorice extract concentration (5, 10) g.l-1 and spraying of Roselle extract concentration (15, 20) g.l-1 as well as compared treatment (spraying with distilled water) in two stage hbabok and Kemri on fruit drop and qualities of Braim cultivar, showed results that the spray in hababok stage and treatment of GA3 concentration 25 mg.l-1 increased of weight and size of the fruit significantly and did not show significant differences between the spray at the stage of hababok and Kemri in influencing the T.S.S., while treatment of spraying liquorice extract concentration of 5 gm.l- 1 increased total soluble solids and dry matter significantly, werever spraying at the stage of Kemri with GA3 increased significantly in water content of fruits, while sprarying in hababok stage increased in dry matter content of the fruits and did not show significant differences between the results of treatments or the stage of spraying in effect of Drop fruits for a cultivar of Braim through the stages of growth and maturity (Khalal, Rutab and Tammar) this results confirms that the phenomenon of drop fruit under the influence of genetic type male and female cultivar.

Research summary
تهدف الدراسة إلى تقييم تأثير بعض المستخلصات النباتية وحمض الجبريليك (GA3) على تساقط الثمار وتحسين جودة ثمار نخيل التمر من صنف البرحي. أجريت التجربة في موسم النمو لعام 2009 في إحدى البساتين في منطقة أبو الخصيب - البصرة. تم رش الثمار بتركيزات مختلفة من GA3 ومستخلص العرقسوس والكركديه في مرحلتي الحبابوك والكمري. أظهرت النتائج أن رش GA3 بتركيز 25 ملغم/لتر في مرحلة الحبابوك زاد بشكل كبير من وزن وحجم الثمار، بينما لم تظهر فروق معنوية في تأثير الرش بين مرحلتي الحبابوك والكمري على المواد الصلبة الذائبة الكلية. كما زاد رش مستخلص العرقسوس بتركيز 5 غم/لتر من المواد الصلبة الذائبة والمواد الجافة بشكل كبير. بينما زاد رش GA3 في مرحلة الكمري من محتوى الماء في الثمار بشكل كبير. تؤكد النتائج أن ظاهرة تساقط الثمار تتأثر بالنوع الوراثي للذكور والإناث من الصنف المدروس.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة لفهم تأثير المستخلصات النباتية وحمض الجبريليك على جودة ثمار نخيل التمر وتحديد أفضل الممارسات الزراعية لتحسين الإنتاجية. ومع ذلك، يمكن توجيه بعض النقد البناء للدراسة. أولاً، كان من الممكن توسيع نطاق الدراسة لتشمل مواسم نمو متعددة لتأكيد النتائج. ثانياً، لم يتم التطرق بشكل كافٍ إلى تأثير العوامل البيئية الأخرى مثل التربة والمناخ على النتائج. أخيراً، كان من الممكن تضمين تحليل اقتصادي لتقييم جدوى استخدام هذه المعالجات في الزراعة التجارية.

Stages of initial callus and embryiods of date palm Phoenix dactylifera L. were histological and chronological studied begging from the ٢nd weeks of culturing segment of shoot tip to ten months in MS medium containing ١٠٠mg/l ٢،٤-D with activated charcoal in the dark. The study reveled that the active meristematic cells were unequally distributed in the explant and concentrated in the shoot apical dome and leaf margin. These cells are the bases from which initial callus started its growth. Somatic proembryo appeared for the first time as a meristematic cells groups separated from each other by relatively thick walls after five months of culturing in continuos culture in the same medium .In progress months (٦-١٠) the small simple proembryos continued into advanced multicell embryos and underwent polarization. Also the embryos were observed with attendance for division and separation into smaller or budded to produce numerous other.
This investigation carried out in 2012-2013,in department of plant protection- Damascus Unv., to study the effect of ethanol and water extracts of Allium sativum L., Inula viscos L., Thymus vulgaris L. and Melia azedarach L., in inhibition mycelium growth of fungi Alternaria alternata and Fusarium oxysporum and compared with fungicides (carbendazim and chlorothalonil) on PDA in the laboratory. The result showed that ethanol extracts of studied species gave significant inhibition to growth fungi compared with the control. The ethanol and water extract of the Allium sativum gave the superior effect inhibition to F. oxysporum where gave 100% inhibition at 600 and 1000 mg/l. at respectively, and gave100% inhibition to A. alternata at 1000 mg/l. Followed with the ethanol extract of Inula viscos. While, the ethanol and water extract of the Melia azedarach gave the lowest inhibition to growth study fungi. Where didn’t gave 100 % inhibition to F. oxysporum and A. alternata at 1000 mg/l. On the other hand, the ethanol extract of Thymus vulgaris gave moderate inhibition to F. oxysporum, while the inhibition of A. alternata was little. The ethanol extract of tested plants gave the superior effect inhibition to both fungi compared with water extracts. On the other hand, the obtained results showed that carbandazim gave the superior inhibition for F. oxysporum ,where gave 100% inhibition at concentration 120 mg/l. While the fungicide chlorothalonil gave the lowest inhibition to F. oxysporum. At contrast, the fungicide chlorothalonil gave the highest inhibition to A. alternata at used concentration. Where cause 100% inhibition at 150 mg/l. On the other hand, Effect of plant extracts and fungicides increased with increase of concentrate. We can arranged the effect of plant extraction at the values (ED50): Allium sativum L., Inula viscos L., Thymus vulgaris L. and Melia azedarach L., Therefore we recommended to use the ethanol extract of the Allium sativum L., Inula viscos L. as environment friendly fungicides.
The lack of information about the cultivation of coriander plant in Syria prompted us to study the effect of four plant densities (33.33،10، 13.33 and 20 plant/m2)، and four levels of phosphate fertilization (0107.2،160.8، and 214.4 of Superphospha te 46%) on some productive and quality traits of the coriander plant. This study was carried out in Tartous province during the growing season 2014، using Randomized Complete Block design with a Split Plot arrangement of treatments. The Results revealed that there were significant differences between the treatments for the whole traits، in addition to a significant interaction between density and phosphate fertilization. Although the densities (10، 13.33 and 20 plant/m2) varied in their effect، they had superiority upon the control(33،33)plant/m2، and the density 10 plant/m2 had more important effect in terms of increasing each of: branches number/plant، seed weight/plant، seeds number/inflorescence، protein content in plants and seeds and beta carotene and chlorophyll. However، the level 160.8k.g/h of P2O5 increased the number of inflorescences/plant، number of fruits/plant and seed weight/ inflorescence.
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.
