نُفِّذ البحث بهدف دراسة تأثير الرش بمستحضرTecamin Flower بتركيز 2.5 مل/ل بالإضافة للرش بالماء المقطر، في النمو الخضري لثلاثة هجن من البندورة، عند مستويين من مياه الري (50 و 100 % من السعة الحقلية) في الموسم الزراعي الربيعي 2016. طبقت 3 رشات بالمستحضر المذكور و بمعدل أسبوعين بين الرشة و الأخرى بدءاً من مرحلة الإزهار. أظهرت النتائج تفوق الهجين ‘Finenss’ معنوياً على الهجينين الآخرين في طول النبات، و عدد الأفرع الكلية، و عدد الأوراق، بينما تفوق الهجين ‘Hadeer’ معنوياً بنسبة المادة الجافة، و محتوى الأوراق من الكلوروفيل. و أدى خفض مستوى الري للنصف إلى انخفاض معنوي في طول النبات و عدد الأفرع الكلية، لكنه أسهم بالمقابل في زيادة عدد الأوراق، و نسبة المادة الجافة للمجموع الخضري. و قد حقق الرش بالمستحضر Tecamin flower زيادة معنوية بجميع مؤشرات الدراسة بغض النظر عن الهجن و مستوى الري مقارنة بمعاملة الرش بالماء المقطر. تفوقت نباتات الهجين ‘Hadeer’ المروية عند مستوى 50 % من السعة الحقلية و المرشوشة بالمستحضر Tecamin flower معنوياً بنسبة المادة الجافة، و محتوى الأوراق من الكلوروفيل. بينما تفوقت نباتات الهجين ‘Finenss’ المروية عند مستوى 100 % من السعة الحقلية و المرشوشة بالمحلول المغذي في عدد الأوراق و المساحة الورقية الكلية للنبات.
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.

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 .
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.
The research was carried out on the farm of Abi Jarash affiliated to the Faculty of Agriculture in Damascus during the 2012 agricultural season for the spring and fall seasons. The experiment was designed in a completely randomized sector method with the aim of evaluating the response of the two potato cultivars (Spunta and Daraga) to water stress.
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 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 ir
on, 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.
