هدف البحث إلى مقارنة هجينين من البقدونس المسطح و المجعد الأوراق في بعض الصفات الفينولوجيـة و المورفولوجية و البيوكيميائية. تمت الزراعة في كلية الزراعة - جامعة دمشق عام 2012 ، و أشارت النتـائج إلى تشابه الهجينين بعدد الأوراق على الساق الواحدة و بمحتوى NO3 ، و لوحظ وجود فرق معنـوي لـصالح الهجين ذي الأوراق المسطحة بالمقارنة مع الهجين ذي الأوراق المجعدة، من حيث مـساحة الأوراق (23.21 و87.10 سم2 على التوالي) و طول الساق (68.11 و 42.5 سم، على التوالي) و وزنا النبات الرطـب (8.56 و 95.31غ، على التوالي) و الجاف (4 و 92.1غ، على التوالي)، في حين كان لنباتات هجين الأوراق المجعـدة ساق أثخن معنوياً بمقدار مرتين بالمقارنة مع الهجين ذي الأوراق المسطحة (69.1مم)، و اتـصف بمحتـوى أعلى من كل من المواد الصلبة الذائبة (7%) بالمقارنة مـع الهجـين ذي الأوراق المـسطحة (6%) و مـن اليخضور و الكاروتين و فيتامين C بمقدار 37 % و 45 % و 61.14 % بالمقارنة مـع الهجـين ذي الأوراق المسطحة (014.0 و 006.0 و 03.21 مغ/غ، على التوالي).
The research aimed to compare the phenological, morphological and biochemical characterestics of plain and curly-leafed parsley hybrids. The hybrids were similar in germination percentage and leave number as well as in the content of NO3. Significant differences were observed in leaf area of plain and curly-leafed hybrid (21.23 vs. 10.87 cm2), stem length (11.68 vs. 5.42 cm), fresh (56.8 vs. 31.95 g) and dry weight (4 and 1.92 g, respectively). Comparing to plain-leafed, the curly-leafed hybrid had a twice thicker stem, higher chlorophyll, carotene and vitamin C contents (37,45, and 14.61%, respectively).

Research summary
هدفت هذه الدراسة إلى مقارنة الصفات الفينولوجية والمورفولوجية والبيوكيميائية لهجينين من البقدونس، أحدهما ذو أوراق مسطحة والآخر ذو أوراق مجعدة، تحت ظروف مدينة دمشق. أظهرت النتائج أن الهجينين كانا متشابهين في نسبة الإنبات وعدد الأوراق، ولكن الهجين ذو الأوراق المسطحة تفوق في مساحة الأوراق وطول الساق والوزن الرطب والجاف للنبات. في المقابل، كان للهجين ذو الأوراق المجعدة ساق أكثر سماكة ومحتوى أعلى من الكلوروفيل والكاروتين وفيتامين C. تم تنفيذ التجربة في مزرعة أبي جرش بجامعة دمشق، حيث تم زراعة الهجينين في ظروف متشابهة وتمت مراقبة نموهما وتحليل محتواهما الكيميائي. أظهرت النتائج أن الهجين ذو الأوراق المسطحة كان أكثر إنتاجية من حيث عدد الأوراق وطولها ومساحة الأوراق ووزنها، بينما كان الهجين ذو الأوراق المجعدة أفضل من حيث محتواه من الفيتامينات والأصباغ. توصي الدراسة بإجراء دراسات فيزيولوجية وجزيئية مستقبلية لتقييم إنتاجية الهجن وجودة المحصول بشكل أكثر تفصيلاً.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مفيدة في تقديم معلومات مقارنة بين هجينين من البقدونس تحت ظروف مناخية محددة. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل توسيع نطاق الدراسة لتشمل مناطق مناخية مختلفة لتقديم نتائج أكثر شمولية. ثانياً، لم يتم التطرق إلى تأثير العوامل البيئية الأخرى مثل التربة ونوعية المياه على نمو الهجينين. ثالثاً، كان من الممكن تقديم تحليل اقتصادي لتكلفة زراعة كل هجين وفوائده الاقتصادية. أخيراً، كان من الممكن إجراء تجارب إضافية لتحديد أفضل موسم لزراعة كل هجين في سوريا.

The experiment was carried out during spring season 2016 to study the effect
of foliar spraying treatment with Tecamin Flower 2.5 ml/L in comparison with
distilled water, on growth of three hybrids of tomatoes at two different levels of
irrigation
(100 and 50 % of field capacity). Three sprays were conducted started
from flowering with two weeks’ interval. The results showed that ‘Finenss’ hybrid
had significant differences in plant height, branches per plant and leaves number per
plant. ‘Hadeer’ hybrid had superiority in dry matter ratio and content of chlorophyll
in leaves. Reducing the level of irrigation resulted in a significant decrease in
plant height, total branches number, versus an increase in the leaves number per
plant, total leaves area and the percentage of dry matter. The results showed that
the treatment with Tecamin flower led to a significant increase in all indicators
studied. The interaction treatments shoed that Hadeer hybrid irrigated in level 50
% and spraying of nutrient solution (Tecamin flower) had a significant increase in
dry matter ratio and chlorophyll content in leaves. While the hybrid Finenss which
irrigated in level 100 % with nutrient solution (Tecamin flower) had a significant
increase in leaves number per plant and total leaves area.
The research was carried out during 2009 – 2010 in Al – Hasaka – Amoda – to study the effect of cattle manure at the rate of 30 ton/h1, and four organic green fertilizers (Lentil, Vetch, Faba bean and Barely) on plant area and earliness properties of
cotton crop compared with chemical fertilizer 400 kg/h1 urea, 83 kg/h1 P2O5 and 25 kg/h1 K2O.The study showed that the cattle manure significantly increased (plant area, lower first fruiting branch, earliness of flowering and boll maturity) when compared with all studied fertilizers, the increase reached (190. 92 Cm2, 0.30 pod, 1.50 day and 0.90 day) respectively. When compared with chemical fertilizer, the legume green fertilizers (Lentil, Vetch and Faba bean) significantly increased the plant area when compared with the control. The legume green fertilizer (Lentil) significantly increased the earliness of flowering (2.73) day and boll maturity (2.21) day when compared with the green fertilizer (Barely). The chemical fertilizer did not significantly affect the earliness of flowering and boll maturity when compared with the legume green fertilizer (Lentil) during the two seasons.
The research was conducted at the Maize Researches Department, General
Commission for Scientific Agriculture Researches (G.C.S.A.R.) Damascus,
Syria during the summer growing seasons of 2010, 2011 and 2012. Treatments
were arranged in a Randomized
Complete Blocks Design with three
replications. The research aimed to evaluate genetic parameters for some traits
like days to 50% silking, plant and ear height, ear length, ear diameter, number
of rows per ear, number of kernels per row, 100 kernel weight and grain yield
per plant using generations means analysis of two maize hybrids (IL.292-06 ×
IL.565-06, IL.459-06 × IL.362-06) to detect epistasis and estimates of mean
effect [m], additive [d], dominance [h], additive × additive [i], additive ×
dominance [j] and dominance × dominance [l] parameters. Results showed that
the additive - dominance model was adequate to demonstrate the genetic
variation and its importance in the inheritance of most studied traits. Nonallelic
gene interaction was operating in the control of genetic variation in most
studied traits. The signs of [h] and [l] were opposite in most studied traits for
the two crosses. Also, the inheritance of all studied traits was controlled by
additive and non-additive genetic effects, but dominance gene effects play the
major role in controlling the genetic variation of the most studied traits,
suggesting that the improvement of those characters need intensive selection
through later generations. The phenotypic variations were greater than
genotypic variations for all studied traits in the two crosses, indicating greater
influence of environment in the expression of these traits. Highly significant
heterosis relative to mid and better parents, respectively was found for all
characters, and this accompanied with inbreeding depression for all traits.
Narrow sense heritability and genetic advance were low in most of the traits
due to the dominance of non-additive gene action in controlling the genetic
variation of the most studied traits and this predict low to medium values of
genetic advance through selection process.
Despite being one of the reasons of production decline, salinity is still a tool
to improve production quality in some hybrids. this research was conducted at
the Faculty of Agriculture, University of Damascus during 2012 season. A salt
stress was
applied on two tomato hybrids, Bonaparte and Marmara by
increasing the value of the electrical conductivity of irrigating water from 4 to
13 ds / m, at the stage of the third true leaf to the end of growth of the two
tomato plants.
Results indicated that salt stress led to a reduction in the fruit weight of
both hybrids but it helped in improving some chemical and physical
characteristics relating to fruit quality, such as increasing the fruit content of
soluble solids in both hybrids. Salt stress did not affect the lycopene content of
fruits in Bonapart, but it was increased by 2 folds inMarmara. Some fruit color
indices (a* and b*) were greater in Bonaparte while L* indice was higher in
Marmara. However, the color indices of fruits were not affected by salinity in
both hybrids studied.
This research was conducted at the farm of Abu-Jarash, Faculty of
Agriculture, Damascus University. The aim of this research was to
evaluate the performance and productivity of 9 bread wheat (T.
.aestivum )and 3 durum wheat T. durum.
The experiment was laid out in a Random Complete Block design
(RCPD) with three replication.
