تضمن البحث دراسة تأثير التسميد الورقي في صنفي العنب حلواني لبنان و كمالي بأربعة مستويات من الحديد المخلبي(Fe-EDTA) و هي (صفر، 50،100 و 200 جزء بالمليون حديدًا) و التسميد الأرضي بالسماد المركب(NPK)بمقدار ( 30 كغم / K2O 30 + كغم P2O 30 كغم 5 + N دونم) و دراسة التداخل بين الأصناف و الحديد و السماد المركب و ذلك خلال موسمي النمو 1995 و 1996. أدى الرش بتركيز 200 جزء بالمليون حديدًا إلى زيادات معنوية في نسبة حيوية و إنبات حبوب اللقاح و طول الأنبوب اللقاحي و نسبة عقد الحبات في العنقود و نسبة إخصاب البويضات في مبايض الأزهار و في المحتوى اليخضوري للأوراق و مساحة الورقة الواحدة و المساحة الورقية للفرع و الكرمة و العنقود. و تم التوصل إلى النتائج نفسها عند إضافة السماد المركب. لقد تميز الصنف حلواني لبنان على الصنف كمالي معنويا في نسبة إنبات حبوب اللقاح و طول الأنبوب اللقاحي و نسبة إخصاب البويضات و في المحتوى اليخضوري للأوراق و مساحة الورقة الواحدة، في حين تفوق الصنف كمالي معنويًا على الصنف حلواني لبنان في المساحة الورقية للفرع و الكرمة و العنقود. أما تأثير التداخل بين الحديد و السماد المركب و الصنف فلقد تبين أن معاملة كرمات العنب المسمدة للصنف حلواني لبنان و التي رشت بتركيز 200 جزء بالمليون حديدًا قد تفوق معنويًا في نسبة حيوية و إنبات حبوب اللقاح و طول الأنبوب اللقاحي و نسبة عقد الحبات و نسبة إخصاب البويضات؛ علاوة على تأثير المعاملة نفسها و معاملة كرمات العنب المسمدة للصنف كمالي و التي رشت بتركيز 200 جزء بالمليون حديدًا في صفات النمو الخضري.
This study was conducted during the seasons 1995 and 1996 at Ninevah Horticulture Station- Iraq. On Halwani and Kamali grape cultivars. This study included four levels of foliar application of Fe-EDTA at concentrations of 0, 50, 100 and 200 ppm iron, and soil compound fertilization with NPK (30 kg N + 30 kg P2O5 + 30kg K2O/ Donum) on the two abore mentioned cultivars, and the interaction among the three studied factors (cultivars, Fe and NPK), was also evaluated. The results showed that 200ppm of iron caused a significant increase in the percentage of pollen viability, Pollen grains germination, length of Pollen tube, setting of berries, ovules fertilization, leaf chlorophyll content, single leaf area, shoot leaf area, and total leaf area per vine and leaf area per cluster. The same results were obtained by using NPK fertilization. Halwani grape CV. Was significantly superior over on the Kamali grape CV. in pollen viabilits, pollen germination, length of pollen tube, leaf chlorophyll content and the single leaf area, While the Kamali grape CV. gave the highest shoot leaf area, total leaf area per vine and leaf area per cluster. The interaction among iron, NPK and cultivars reveded that the best treatment was 200 ppm iron with NPK, which gave the best results concerning flowering, setting and vegetative growth for both the cultivars.

This research was carried out in the laboratories of the Atomic
Energy Commission Molecular Biology and Biotechnology
Department in Damascus to study the molecular characterization of
five of local and introduced grapes varieties which collected f
rom
the Pome and Grapevine Research Center in Sweida using 20
primer pairs of SSR.
Peach (Prunus persica Batsch) transplants cv. Dixired were sprayed three
times a season with three levels of urea (45% N) (2.5, 5.0 and 7.5 gm/ L), and
two levels of iron (10 and 20 mg Fe/ L) using chelated iron Fe-EDDHA
(6%iron), each alone or in
combination. Meanwhile the control transplants
sprayed with distilled water during 2006 and 2007 growing seasons, twenty
days intervals between each spray and another, the first spray is done at the
first week of May in both seasons. Results indicated that all spray treatments
with urea and iron each alone or with each other significantly increased leaves
N, K, Fe, chlorophyll and carbohydrate concentration, transplant leaves area,
shoots number, transplants height, main stem diameter and vegetative and root
dry weight. While leaves P concentration, significantly decreased with the foliar
spray with two concentrations of iron alone, or in combination with all
concentrations of urea. The best treatment was 7.5 gm urea/ L + 20 mg Fe/ L.,
which gave the highest means of all studied parameters, except leaves P
concentration, which were the highest mean of it was in the control treatment
at both seasons.
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 carried out to study the effect of summer pruning on the growth and production of two grape varieties Vitis vivifera L. Halwani and Baladdi. The study was conducted in Kadmous during 2012 growing season on two varieties of grape tre
es reared on wiredraw. Seven treatments were used: 1- control, 2- shoot thinning, 3- shoot thinning and hedging, 4- shoot thinning and axillary shoot removal, 5- shoot thinning and axillary shoot removal, 6- shoot thinning and axillary shoot removal and leaf removal, 7- shoot thinning and leaf removal.
Results show that hedging improves weight of cluster and berry due to the increase in fruit set percentage which leads to an increase in grape production. Shoot thinning increases TSS yet other processes have negative effects: the hedging process increases acid titration in the Baladdi cultivar but in the Halwani cultivar hedging and axillary shoot removal increases acid titration.
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.
