Abstract: This investigation was carried out at the Experimental orchard, Faculty of Agriculture, Assiut University, Egypt, to study the effect of CPPU spraying and pinching on cluster and berry traits of Roomy Red, as well as, effect of berry thinning and GA3 application on cluster and berry traits of Ruby Seedless grapes during 2007 and 2008 seasons. The experiment was set up as complete randomized block (CRB) with four replicates, one vine per each. Pinching of both shoots and flower clusters as well as brushing and spraying solutions were performed at full bloom. The obtained results could be summarized as follow. GA3 at 1.5 or 3.0 ppm spraying, brushing flowers cluster or 1% Urea vine foliage spraying at full bloom significantly decreased the berries number, weight and compactness coefficient of clusters compared to untreated one. All berry thinning reduced the berries number and increased the length of clusters, hence induce a pronounced decrease in compactness coefficient and produced losse clusters. GA3 at 1.5 to 3.0 ppm and Urea at 1% spraying and brushing the flowers cluster at full bloom significantly increased the berry weight, total soluble solids, reducing Sugars and anthocyanin in berry skin compared to untreated ones On the other hand, CPPU spraying of shoots and flower clusters at full bloom significantly increased the berries number, weight and compactness coefficient of clusters compared to untreated ones. CPPU spraying at full bloom gave the highest there cluster traits compared to pinching ones. CPPU spraying and pinching either shoots or flower clusters at full bloom significantly increased the berry weight and improved the chemical constituents of juice and skin anthocyanin of berries compared to untreated ones. It could be concluded that, the best methods for berries thinning of Ruby Seedless grapevines that whether GA3 at low concentration, 1.5-3 ppm or brushing the flower cluster at full bloom to overcome the adverse effects of GA3 at high concentration. Furthermore, to overcome the unfavorable phenomenon's of Roomy Red grapevine clusters, must using either CPPU 2.5 to 5.0 ppm spraying or pinching the shoot tips alone or along with flower cluster tipping at full bloom.

ABSTRACT During 2013/ 2014 and 2014/2015 seasons, Valencia orange trees received three sprays; at growth start, directly after fruit setting and after one month with three plant oils; clove, ginger and turmeric each at 0.025 ,0.05 and 0.1% besides the control treatment. Treating the trees three times with oil of clove, ginger or turmeric each at 0.025 to 0.1% effectively stimulated yield, fruit quality, leaf area and leaf content of pigments, N, P, K and Mg comparing with the control treatment. The promotion was related to the increase in concentrations of these plant oils. Negligible stimulation on all the previous parameters was revealed among the higher two concentrations namely 0.05 and 0.1% . Using oils of clove, ginger and turmeric was effective in an ascending order in this connection. It could be concluded that spraying Valencia orange trees grown under Assiut region conditions with turmeric oil (0.05%) three times resulted in the highest yield and the best fruit quality.

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.
