The effect of different harvesting dates on the quality and storage ability was studied for fruit of Coscia pear cultivar, which planted in the area of Daher Aljabal- Sweida during two successive seasons 2007-2008. Fruit were harvested in three different dates by week time intervals and stored for seven months at (0-1 Cº and 90-95 % RH) in the storage units of apples and vine research department. The effect of harvesting dates of fruit on the physical and chemical properties was determined during period of 7 months in cold storage, by month time intervals. The second date of harvest affected by decreasing weight loss percentage, decay percentage, titratable acidity T. A, starch content and firmness, in addition to that total soluble Solids T. S. S, number of acidity PH, storage ability and shelf life were increased compared to the harvested fruit in the different dates.

Research summary
تتناول هذه الدراسة تأثير مواعيد الحصاد المختلفة على جودة وقدرة تخزين ثمار صنف الكمثرى 'كوسيا' المزروعة في منطقة ظهر الجبل في السويداء خلال موسمي 2007-2008. تم حصاد الثمار في ثلاثة مواعيد مختلفة بفواصل زمنية أسبوعية وتم تخزينها لمدة سبعة أشهر في وحدات تخزين التفاح والعنب بدرجة حرارة (0-1 درجة مئوية) ورطوبة نسبية (90-95%). تم تحديد تأثير مواعيد الحصاد على الخصائص الفيزيائية والكيميائية للثمار خلال فترة التخزين البارد على فترات زمنية شهرية. أظهرت النتائج أن موعد الحصاد الثاني كان له تأثير إيجابي من خلال تقليل نسبة فقدان الوزن ونسبة التعفن والحموضة القابلة للمعايرة ومحتوى النشا والصلابة، بالإضافة إلى زيادة المواد الصلبة الذائبة الكلية ودرجة الحموضة وقدرة التخزين وعمر الرف مقارنة بالثمار المحصودة في المواعيد الأخرى.

Grape Vitis Vinifera L. var. "Baladi" was fumigated with acetic acid at two concentrations 75 and 100 %, during two successive seasons 2008/2009, to study their effect comparing of sulfur dioxide pads and control. However, Sulfur dioxide pads were packed in 40 μm polyethylene bags thickness at two concentrations 1 and 1.5 g/ kg fruit. All treatments were stored at 0 ± 1 Cº and 90-95% RH for three months, in cooling units of pome and vine research department in Swaida. Chemical and physical properties were assessed every 15 days intervals, and in every time shelf life was measured for three days at room temperature and calculated as total loss %. Acetic acid treatment effected as well as or better than sulfur dioxide pads during cold storage. Which, acetic acid fumigation decreased weight loss %, decay % and berry shatter %, moreover, berry adherence strength (g) and berry firmness (kg/cm2) were increased, but T.S.S %, total acidity % and sugars % have not significant differences comparing to sulfur dioxide fumigation and control. In addition to that, the application of acetic acid increased shelf life in days by decreasing total loss %; also this treatment improved some sensory properties and was satisfied for consumer demand.
This investigation was done to study the effect of spray for two times with CaCl2 0.5% and 1%, high potassium fertilizer and dipping with 2% CaCl2, in addition to packaging with polyethylene films on the storability of pear fruits "Coscia C.V". Th e results showed the significant superiority of high potassium fertilizer treatment on the other treatments concerning total and single sugars after harvesting time, while there weren't significant differences between the other treatments concerning the remaining indicators. After four months of storage, the packaging treatments were able to the significantly reduction of weight loss, in addition to preserving the firmness and total soluble solids in the comparison with unpackaged ones, the average of weight loss in unpackaged treatments was 15% and 0.65% in packaging treatments, which led to stop the storage of unpackaged treatments and continue packaging treatments until 7 months. After 7 months, the results showed that the dipping with 2% CaCl2 revealed the high weight loss, while was the least with high potassium fertilizer treatment, on the other hand there were no significant differences between treatments for firmness, total soluble solids and tetra table acidity, while total and single sugars showed significant differences between treatments. Moreover, the sensory tests assured the importance of packaging with CaCl2 treatments to improve storability and quality of pear fruits, which CaCl2 1% packaging treatment got the highest values for most of sensory tests.
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.

Apple Fruits (Malus domestica Bork. cv. 'Golden Delicious') were harvested at three successive dates with intervals of one week between each date. The fruits were packaged with polyethylene films and then stored at 0±1 oC to study the effect of th ese factors on the quality of the fruits and their role to reduce weight loss after harvest. The natural loss of the fruit weight and quality indices: fruit firmness, total soluble solids, titrable acidity and starch content were studied.
