Abstract This investigation aimed to study the effect of paraffin oil and polyethylene bags used separately or in combination on storage quality of "Manfaluty" pomegranate fruits during storage throughout 2012 and 2013 seasons. Fruits were stored at 5 °C with 85-90% RH and room temperature at 22 ± 5 C°. Generally, the storage period in the present study was 45 days at room temperature and 90 days at cold storage. All treatments, namely, coating with paraffin oil, packing with polyethylene bags and combination of both coating and packing, significantly decreased weight loss % and decay % of stored Manfalouty fruits compared with untreated fruits (control) under both storage conditions during 2012 and 2013 seasons. Concerning the chemical properties, total soluble solids (T.S.S) % and acidity gradually increased with the progress of storage period, under all storage conditions during both tested seasons. At the end of storage period the treated fruits with polyethylene bags + paraffin oil contained the lowest values of T.S.S and acidity % while the untreated fruits (control) had the highest percentage of both properties. Juice volume decreased with the extending of storage period and reached the minimum values after 45 days at room temperature and 90 days under cold storage during both investigated seasons. The highest juice content was obtained by polyethylene packing + paraffin oil coating, while the lowest content was found in untreated fruits (control).

Abstract This study was carried out during 2011 and 2012 seasons on "Manfalouty" pomegranate cv. grown at the experimental orchard of Pomology Department, Faculty of Agriculture, Assiut University. The objectives of this study were examining the effects of pre-harvest spray with CaCl2 (4%) and GA3 (100 ppm) as well as post-harvest treatments with jasmine oil (2.5 cm3/L), olive oil (2.5 cm3/L), fiber gard (20 cm3/L) and wrapping individually fruit with food polyolefin stretch as an improving effect in physicochemical characteristics of "Manfalouty" pomegranate cv. during storage under room temperature (22+5°C). The experiments were set up on split-plot arrangements in complete randomized block design (CRBD), with three replicates, 20 fruits each. According to the obtained results of this study, it could be deduced that pre-harvest spray with GA3 (100 ppm) gave in general, the best results on improving physical and chemical characteristics, followed by CaCl2 (4%) during the two growth seasons, as well as wrapping individually fruits with food polyolefin stretch gave the best quality during shelf-life period, followed by dipping fruits in both jasmine oil or olive oil and fiber gard during fruit storage under room temperature. Therefore, the authors recommended with wrapping individually fruits to keep fruits with good quality during fruit storage under room temperature.

ABSTRACT The effects of spraying barley seed sprout and/ or potassium silicate each at 0.025 to 0.1% on fruiting of Red Globe grapevines was examine during 2015 and 2016 seasons. The selected vines were sprayed three times with such two stimulants. Barley seed sprout and potassium silicate each at 0.025 to 0.1% single and combined applications improved growth aspects, leaf pigments, some nutrients, berry setting %, yield and fruit quality compared to the control treatment. Using combined applications was superior to using each alone.The effect on these parameters depended on increasing concentrations. Spraying a mixture of barley seed sprout and potassium silicate three times each at 0.05% improved yield and quality of Red Globe grapevines under Minia conditions

Abstract The effects of GA3 and CPPU on fruiting of Seewy date palm grown at the Experimental Orchard, Faculty of Agriculture, Assiut University, Egypt were investigated during 2013, 2014 and 2015 seasons. All treatments were sprayed after two or eight weeks of pollination. The experiment was set up in a complete randomized block design with five replications of one bunch each. The obtained results could be summarized as follow: - Fruit set and fruit retention percentage were significantly decreased due to spray GA3 at 50 ppm after two weeks of pollination followed by GA3 or CPPU after eight weeks of pollination compared to unsprayed one (control). - Spraying the bunch with GA3 twice, once at 50 ppm after two weeks of pollination followed once GA3 at 75 ppm plus CPPU at 7.5 or 15 ppm after eight weeks of pollination gave the highest fruit weight, flesh percentage and dimention of fruits compared to unsprayed ones. - Spraying GA3 and CPPU significantly improved the chemical fruit properties in terms of the total soluble solids and sugar contents and significantly decreased the total acidity and total soluble tannins percentages compared to unsprayed ones. So, it concluded that spray GA3 at 50 ppm after two weeks of pollination plus either GA3 at 75 ppm and CPPU at 7.5 ppm or GA3 at 75 ppm and CPPU at 15 ppm to obtain the high yield with good quality of Seewy dates. GA3 reduce the fruit retention and consequently increase the fruit weight and size induce increased the yield. CPPU induced an increase in fruit weight and size then get high yield of Seewy dates. Thus, spraying the bunches of Seewy date palm with GA3 and CPPU had get the heaviest yield with improvement the physical and tested chemical fruit properties
