Abstract: The experiment included three Egyptian pomegranate cultivars namely as Manfalouty, Hejazy and Nab-El-Gamal. The study aimed to assess some physical and chemical characteristics in the fruits and estimate their content of some anti- oxidants at different stages of development. The study revealed that there were significant differences between the stud- ied cultivars in most traits. The average weight and fruit dimension (length and diameter) significantly increased and reached their maximum values at 165 days after full bloom (maturity stage). Total soluble solids (TSS) and sugars increased while the acidity gradually decreased until they reached the optimum level in ma- turity. Vitamin C concentration increased progressively until the fruits reached their maturity. The total phenolics content (T.P.C) measured in the fruit peel and arils started high, and then there was a gradual decline until they minimized at fruit maturity. Total anthocyanin content of pomegranate arils and peel began low for the three cultivars and gradually increased till the end of fruit develop- ment. Hydrolysable tannin content (as mg tannic acid/ gm of dry weight basis) in peel and lit. of juice began high and rapidly decreased reaching its lowest level at fruit maturity. The differences were significant between the studied cultivars in both seasons for most abovementioned attributes.

Abstract This study was carried out during 2011, 2012 and 2013 seasons on eight date palm cultivars namely Zaghloul, Haiany, Halawy, Eraby, Bent Aisha, Samani, Sewy and Amry grown at the Experimental Orchard, Faculty of Agriculture, Assiut University, Egypt. The main objectives of this study were to: 1- Compare the morphological characteristics of the bunches of eight date palm cultivars. 2- Study the relation between bunch emergence level and its morphological characteristics. 3- Determine the optimum patterns and fruit thinning percentage of the eight cultivars. The results of the present study showed that bunches and strands morphological characteristics were differed according to the cultivar and bunch emergence level. All the studied characteristics tended to increase according to bunch emergence level from lower to upper. Fruit thinning percentage determined according to cultivar and bunch emergence level. It is worth notable that cutting back (1 cm) of strand, reduced the initial fruit load by 3.11, 3.74 and 4.64% as average of upper, middle and lower bunches respectively for tested cultivars. So the fruit thinning method could be selected according to the bunch and their strand characteristics. This study is important from economic and cultural view to obtain high yield with good fruit quality of date palm production.

Abstract: This investigation was carried out during three seasons i.e. 2010, 2011 and 2012 on Flame Seedless grapevines grown in sandy soil in El-Karnak vineyard for table grapes production, Luxor governorate, Egypt. Ten combined treatments of GA3, urea and active dry yeast spraying at various stage of berry development were evaluated. The experimental vines were arranged in a complete randomized design with three replications per treatment, two vines each. From the results of this investigation it could be concluded that spraying with GA3 seven times, once at pre-bloom (5 ppm), thrice at full-bloom (2.5, 5 and 7.5 ppm) and other thrice when the berry at (6 mm) pea stage (30, 30 and 20 ppm). As well as, combined spraying GA3 four times once at pre-bloom and thrice at full-bloom plus 0.4% active dry yeast when the berry at pea stage to obtain heavy and less compact cluster and hasten the ripening with fairly good Flame Seedless berries quality. In addition, it could be used urea and yeast instead of GA3 in grape production to overcome the adverse GA3 effects especially for colored cultivars.

Abstract This investigation was conducted during two seasons of 2012 and 2013 to study the effect of some post- harvest treatments on storability and quality of Manfalouty pomegranate fruits during storage at ambient temperature. The storage treatments are Nigalla sativa coating oil or wrapping singly or in combination. Sample of each treatments were randomly taken weekly. The obtained data illustrated that undesirable fruits percentage and fruit weight loss %, increased by extending room temperature storage period till 7 weeks. The most clear reduction was associated with untreated fruits where the less values were related with fruit oil coating or fungicidal tissue paper wrappeing singly or in combination. While, juice volume per 100 gm arils gradually decreased by extending room temperature storage period Generally, all treatments of oil coating or any of wrapping materials singly or in combination of oil +fungicidal treated tissue paper wrapping, Nigella sativa essential oil, Nigella sativa essential oil coating + perforated polyethylene wrapping, fungicidal treated tissue paper wrapping and perforated significantly reduced the undesirable fruit and fruit weight loss percentage and significantly increased the juice volume contents compared the untreated fruits during room temperature storage for seven weeks . Its clear to notice that prolonging room temperature storage for 7 weeks caused an increase of total soluble solids % and TSS/acid ratio. While Titratable acidity and vitamin C contents in stored fruits were reduced. Moreover, all treatments significantly decreased the TSS, acidity and increased the TSS/acid ratio and vitamin C content compared to untreated ones. So, it could be concluded that it is important to use Nigella sativa essential oil coating and polyolephinic heat-shrinkable film wrapping to extend the storage life of pomegranate fruits and kept the original quality of the freshly harvested of Manfaluty pomegranate fruits
