نفذت التجربة خلال موسمي (2015 و 2016) على أشجار الليمون الحامض صنف "الماير" بهدف دراسة تأثير التغذية الورقية بعناصر (البورون و الزنك و الحديد) في الصفات الفيزيائية و الكيميائية للثمار و رشت هذه العناصر بشكل منفرد (كل عنصر لوحده) أو على شكل خليط . تم حساب متوسط كلاً من (طول ، قطر ، صلابة ، وزن و حجم الثمرة) علاوة على ذلك حجم العصير و سماكة قشرة الثمرة، كما درست الصفات الكيمائية لعصير الثمار (المواد الصلبة الذائبة الكلية، السكريات الكلية، الحموضة الكلية ، فيتامين سي) و لوحظ زيادة في جميع المؤشرات المدروسة في المعاملات المرشوشة مقارنة بالشاهد من قيم بالمادة مل عصير (%6.37-%3.33-%0.37-34.57مغ %) إلى قيم (-%9.33 %4.88- 1.89%- 43.5مغ %) في الموسم الأول و إلى قيم (-%9.75 %5.87- 3.32%- 45 مغ %) في الموسم الثاني على الترتيب ، و بنتيجة التحليل الإحصائي تبين وجود فروق معنوية بين جميع المعاملات المدروسة و معاملة الشاهد مع تفوق معاملة الرش بخليط من البورون و الزنك و الحديد معاً في معظم المؤشرات المدروسة في الموسمين على باقي المعاملات، أما بالنسبة لسماكة قشرة الثمرة فلم يظهر التحليل الإحصائي أية فروق معنوية بين المعاملات.
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 These 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.

The research experiment was carried out during the 2007, 2008 and 2009
seasons on grape variety Al- Helwani (10 years old) to study the effect of NPK
fertilization rates and the triple superphosphate (T.S.P) application method on
some fruits chara
cters.Three fertilization NPK rates were used, rate 1
(75:25:50) kg/ ha, twofold and fourfold of rate 1, in three replicates in addition
to control. The application of (T.S.P) was on soil surface and at 30 cm depth.
The results showed significant increase of the total soluble solids (TSS), pH and
vitamin C compared to control. while the content of TSS in juice increased by
40.9%, 44.6%, 50.3% in the three rates, respectively, compared to control, pH
increased from 5.45 in control to 5.92; 5.89; 5.73 in the three rates,
respectively, in turn, significant decrease in total acidity (TA) was noted by
15.3, 11.1 and 42.8%, in the three rates, respectively, compared to control.
ASignificant increase of (TSS) by 2.5% and vitamin C by 10 % in deep T.S.P
application compared to the surface application, on the other hand, (TA)
decreased significantly by 4.2%, while, there was no significant differences in
pH, in both treatments.
The aim of this investigation is studying effect of heat treatment and polyethylene packaging method in storability and quality of lemon fruits' Monachello and Enterdonato'. The experience was carried out in cold store of agriculture college in /Dama
scus university/, lemon fruits were stored at 10°c and 85% humidity for 180 days. laboratory experiences was carried out in laboratory of department of horticultural science in the same college during 2010-2011&2011-2012. Part of fruits were packaged in polyethylene bags with 30 microns, the other part of fruits dipped with hot water (62°c for 3 seconds)+ fungicide then were packed in polyethylene packs in addition to the control which untreated and unpacked.
The obtained results indicated the significant effect of dipping and packaging in perforated and unperforated bags treatments in maintain fruits quality of 'Monachello and Enterdonato' until the end of storage. maintaining of (32.89 and 39.06%( juice rate of Monachello respectively, and(11.05 and10.01%) of Enterdonato respectively. (35.27 and 36.57 mg/100ml (vitamin C of Monachello and (18 and11.07mg/100 ml( of Enterdonato, respectively.
On the other hand, the present investigation showed the positive effect of packaging treatment with 30 microns packs by reducing the weight loss for two sorts which was (51.94 and 68.83%) in dipping and packaging in perforated bags treatment respectively, and the important role to stop fruit decadence, and conserve their marketing specification until end of storage.
Orange fruits are characterized at harvesting with physical and sensory
properties determine consumer acceptance and in order to identify these
characteristics and vulnerability storage and irradiation conditions, Valancia
orange fruits were subje
cted to gamma irradiation at doses of 0.0, 0.5, 1.0, and
1.5 kGy using gamma 60Co irradiator facility. Fruits were kept in a refrigerator
for 18 weeks. Results indicated that physical and sensory properties of Valencia
orange fruits were affected by storage time and irradiation. The overall color
differences were increased and the firmness of fruits and skin were decreased.
The used doses of gamma irradiation increased the overall color differences of
fruit skin. Whereas the fruit firmness, and the sensory properties (aroma,
color, test and firmness) of irradiated Valencia orange fruits were decreased.

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 ).
