أجريت الدراسة خلال عامي 2011 و 2012 في مخابر قسم وقاية النبات في كليـة الزراعـة و قـسم الكيمياء في كلية العلوم بجامعة دمشق. بهدف تحديد نسب الحموض الدسمة فـي زيـت البـذور الجافـة و الخضراء و أزهار شجرة الأزدرخت .L azedarach Melia باستخدام الكروماتوغرافيا الغازية. أظهرت النتائج وجود أربعة حموض دسمة بنسب مختلفة في بذور الأزدرخت و أزهارها، و كانت نـسبة الحمـوض غير المشبعة مرتفعة نسبياً في البذور الجافة و الخضراء، فقد وصـلت إلـى 66.88 % و 43.85 % علـى التوالي، إذْ كانت نسبة حمض الكتان هي العليا تلاه حمض الزيت. في حين كانت نسبة الحموض المشبعة مرتفعة في زيت الأزهار (97.39%) إذ كانت نسبة حمض الشمع هي العليا تلاها حمض النخيـل. كمـا قُيمت فاعلية المستخلص الزيتي للبذور الجافة و الخضراء و لأزهار الأزدرخت في تثبـيط نمـو الفطـرين cinerea Botrytis و digitatum Penicillium على الوسط المغـذي PDA ، و قورنـت بالمبيـدات الفطرية القياسية procymidone و benomyl في المخبر.
The investigation was carried out during 2011-2012 at the laboratories of Plant Protection Dep., Faculty of Agriculture, and Chemistry Dep., Damascus University. The fatty acid composition in the seed and flower of Chinaberry (Melia azedaracht L.) was studied by Gas Chromatography. Results showed that four fatty acids with different rate in seed and flowers of Chinaberry. The ratio of unsaturated fatty acid was highly in dry and fresh seed oil and reached 88.66% and 85.43%, respectively. Where the percentage of linoleic acid was higher than oleic acid. The percentage of saturated fatty acids was highly in oil flowers (39.97%), where the ratio of stearic acid was the highest followed by palmitic acid. Tthe efficacy of oil extract of dry, fresh seed and flowers Chinaberry for suppressing the growth of the fungi, Penicillium digitatum and Botrytis cinerea on artificial media in comparison with standard fungicides, benomyl and procymidone under laboratory condition was also evaluated.

The aime of this study was to isolate and identify the seed borne fungi of two
varieties of Soybean, Sb172 and Sb44, using blotter method and P.D.A plate method.
21 species belong 10 genus were determined, saprophyte and pathogen Fungi.
P.D.A plat
e method showed the highest number of fungi in comparison with the
other method, and the fungus Aspergillus was the most frequent genus with a ratio of
44.2% for the variety sb172 and 45.14% for the variety sb44, followed by the fungus
Cladosporium and then Fusarium, whereas the genus Colletotrichum showed the lowest
frequent ratio (0.85%) with the variety Sb172.
The percentages of seeds germination and infection were differed between the two
varieties, and the ratio seeds germination of variety sb172 were higher than the variety
sb44 with the both methods of culture, and were equal 94% with prim variety and 92%
with the second ones by blotter method, whereas the ratio were 52% and 34% for both
varieties respectively by P.D.A plate method. However, the ratio of infection were, in
general, lower with prim variety than the second ones by the both method.
The results showed the seeds which were highest ratio infection appeared low ratio
germination .
The effect of different culture medias (water, MS solid, MS 1/2 solid) on germination
and growth of heliotropiun hirsutissimum Grauer. in vitro was studied with different
concentrations of gibberellic acid (0.001-0.01-0.1 and 1 mg/l).
The results
showed that best germination rate (80.5%) and root (20mm) and shoot
(35mm) growth were obtained in MS solid medium with 0.1mg/l GA3.
Addition of 0.1mg/l GA3 to MS1/2 solid medium improved germination rate
(75.44%), root (19mm), and shoot (24mm)growth.
When GA3 (0.1 mg/l) was added to water medium, germination rate reached
(65.33%), as well as root and shoot growth (12.66mm and20mm) alternatively after 2
weeks of planting.
Seedling of MS solid medium were transferred into pots contained torp medium to
adapting them with outside environment, and then surviving their growth until maturity
after 4 weeks.
This study was conducted to study the effect of including
different levels of Grape seed oil as a natural antioxidant on
layer hen egg production, egg quality,.
this study was carried out during summer 2014 in Siano Research Station- the
Agricultura Research Center in Lattakia . Four varieties of Cowpea: Dolicho (entrance),
Blackey (entrance), Almaarefa (Local) and local
cultivar were planted and compared
concerning the vegetative growth , productivity
and quality of green pods.
The results showed the superiority of Almaarefa cultivar in some vegetative traits
:plant hieght (166.66) cm compared with local cultivar 116.58 cm ,number of leaves on
plant and( 27) leaves and( 17) leaves for local cultivar, and plant leaves area( 7840.23)
cm2 for Almaarefa comparing with( 4499.75) cm2 for local cultivar
As well as it had a maximum pod length( 16.71) cm and highest grain number of
pod( 9.44) ,while Blackey cultivar was the most superior comparing with
other cultivars in productivity( 0.6229) kg \ m 2 and pod's number/m2 ( 81.069)
Whereas Almaarefa had the lowest productivity( 0.4935) kg/m2 and lowest pod's number
( 65.89)pod/m2.
The results also showed that the local cultivar had the most vitamin C content
comparing with other cultivars by( 23.765%) and in dry matter by (15.38%) , while
there was no significant differences between protein green pods content.
Some local natural sources of antioxidant such as orange peel extract (Citrus
sinensis), pomegranate peel extract (Punica granatum) and ginger extract
(Zingiber officinale L.) were evaluated during 5 days storage of refined palm oil
at 63°C as com
pared to the synthetic antioxidant such as propyl gallate. The
above extracts were obtained with ethanol and oil (palm oil). Those extracts
were added to the oil at two different levels (100 ppm and 200 ppm).
Antioxidant activity of natural extracts, synthetic antioxidant and the control
treatment without antioxidant under thermal treatment (Schaal test) was
assessed by measuring acid value (AV), peroxide value (PV), iodine value (IV)
and refractive index (RI) during 6 days storage of refined palm oil at
temperature mentioned above. Antioxidant activity also measured by studying
the stability of oil by the use of rancimat method. All treatments exhibited
antioxidant activity. Statistical analysis results were shown that the
pomegranate peel extract treatment was significantly (P<0.05) superior than
the orange peel extract and ginger extract treatments whereas, it was not
significant difference about propyl gallate treatment.
