تمت دراسة تأثير بعض عمليات التقليم الصيفي (الأخضر) في نمو صنفي العنب المحليين حلواني و بلدي التابعين للنوع .Vitis vinifera L, و إنتاجهما أُجريت الدراسة في مزرعة خاصة في منطقة القدموس خلال العام 2012, على شجيرات عنب مرباة على أسلاك من الصنفين المذكورين, و شملت 7 معاملات (1- شاهد, 2- تفريد, 3- تفريد و قصف, 4- تفريد و قصف و تفريع, 5- تفريد و تفريع, 6- تفريد و تفريع و توريق, 7- تفريد و توريق). أظهرت النتائج تأثير عملية القصف في تحسين وزن العنقود و الثمرة و ذلك نتيجة تأثيرها في تحسين نسبة العقد الأمر الذي انعكس إيجاباً على إنتاج الشجيرة و على الصنفين موضوع الدراسة, كما حسنت عملية التفريد فقط نسبة المواد الصلبة الذائبة الكلية بعكس بقية العمليات المنفذة, كما أدت عمليتا القصف و التفريع دوراً في زيادة نسبة الحموضة الكلية.
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 trees 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.

This study was conducted to examine the effect of storage period and fruit
wrapped of two local grapes varieties (Balady and Helwany) using polyethylene
bags of 50 μm thickness on some losses of grapes berry . the study estimated the
weight loss p
ercent, berry shatter, berry spoilage and the total losses for the
varieties as a function to storage period and packing of grapes berry. Results
showed that there is a high correlation between the storage period and the
weight loss, berry shatter, spoilage and the total losses of fruits, where this
action started after 3 weeks of the beginning of storage. The average percents of
weight loss after 100 days storage were 11.75 % and 8.43% for Balady and
Helwany respectively, the berry shatter percents were 6.20% and 5.52%
respectively for Balady and Helwany, the spoilage percents were 9.50% and
7.20% for Balady and Helwany respectively and the total losses for tow
varieties were 20.1% and 13.63% for Balady and Helwany respectively. The
previous values decreased clearly by using bags of polyethylene of 50 μm
thickness as follows: 9.47% and % 6.82 for weight losses, 3.10 % and 1.8% for
berry shatter, 7.20% and 3.51% for spoilage and the total losses 16% and
10.1% for Balady and Helwany respectively.
The investigation was conducted during 2013-2014 in Al-Moroj - Baniyas - Tartous.
The effect of grafting cucumber (Hybrid Amir F1 and Potenza F1) on (TZ 148 F1)
rootstock on growth and production was studied. The experiment contained 4 treatments
(ungrafted Amir F1 and Potenza F1, and grafted ones on Cucurbita hybrid).
The results showed that grafted cucumber (Amir F1) on (TZ 148 F1) was significantly
superior to other treatments in leaf area (15368.79 cm2.plant-1) and total production (21.58
kg .m-2). Grafting cucumber (Potenza F1) on (TZ148 F1) leaded to a significant decrease in
each of plant height (113.25 cm), number of secondary branches (7.5 branch . plant-1),
number of female flowers (94.13 flower . plant-1), number of fruits (38.13 fruit . plant-1)
and total production (14.61 kg .m-2). The earliness in grafted cucumber (Amir F1 and
Potenza F1) on (TZ 148 F1) (0.19 and 0.28 kg .m-2 respectively) was significantly
decreased compared to ungrafted plants (0.43 and 0.54 kg .m-2 respectively). Grafting on
(TZ 148 F1) didn't affected the fruit qualitative characteristics.
The research was aimed to study the effect of olive press methods on the oil quantity and quality. The results showed the following:
The method of press Olive effect to the quantity of Olive oil so the results of oil quantity from olive fruite p
ress in mechanical olive press method more above from half mechanical method and from traditional method ( the witness). The increase of quantity between mechanical and traditional method was 60% and between mechanical half mechanical method was 27% and bween half mechanical and traditional method was 28%.
The method of press Olive effect to the of Olive oil quantitatively the results of oil quantitatively from olive fruit press in mechanical olive press machines to surpass half mechanical olive press that is the flavor and color best and Acidity presumption and peroccid number is less .
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.
In this research, we have studied the effects of some summer pruning at the
mid June and Juli, in addition to the common periodical winter pruning during
February.
Both studies were done to evaluate calcium concentration of fruits, quality
and yi
eld the apearance of physiological disorders during the storage and
fruits. Experiments were conducted on 8 year apple trees of Starking Delicious
and Golden Delicious, which are sensiitve to laek of calcium and as a result
caused bitter-pit as an important physiological disorder on apple fruits.
Summer pruning of apple trees at mid june increases their content of
calcium and their colors, also decreases physiological disorder, weight loss
during storage, without affecting the annual yield of trees.
Accorrding to the attained results, we recommend the farmers of apple trees
to follow summer pruning, because of its benefits on improving the condition of
trees and achieving the balance between vegetative and generative growth, and
reduced the alternate Summer pruning. Also improve the quality of fruits, their
storability and their resistance for some physiological disorders during storage.
