Due to the rising interest in healthy products, super foods such as pomegranate have spread widely on the international market in recent years.  Several postharvest treatments have been applied in order to maintain the quality and extend shelf life of pomegranate arils. This study evaluated the effect of Arabic gum treatment as well as different edible coatings (Jojoba oil, Gelatin, Wheat Germ oil and Rosemary oil) on shelf life and fruit quality parameters of Wonderful pomegranate during cold storage at 5oC with 85-90% relative humidity for 45 days. Fruit characteristics, such as fruit weight, volume, firmness, and weight loss%, total juice weight and volume, total soluble solids, total acidity, ascorbic acid (Vitamin C), total anthocyanin, total sugars % and total phenols were determined periodically along a storage period of 45 days. It is clear that, all fruit characteristics were positively affected by different edible coating treatments. Pomegranate fruits coated with rosemary oil at 2% in combination with Arabic gum at 10% effectively reduced weight loss%, maintained higher firmness, fruit weight, fruit volume, juice weight and juice volume.

This investigation was carried out through two successive seasons (2014 and 2015) to investigate the effects of nano-carbon and nitrogen fertilization levels on growth, leaf mineral content, yield and fruit quality of 3 years old flame seedless grapevines, cultivated in a private orchard with loamy soil texture, at Gharbiya Governorate. Ten treatments were applied as a randomized complete block design with three replications. The result indicated that 80%N from recommended re-quirment+0.6% carbon nano tubes (CNTs) increased significantly leaf area, fresh and dry weight, total carbohydrate% and concentration of N, P, K, Mg, and Fe in leaves, weight of 100 berries, and juice weight of 100 berries compared with control. Also results showed that yield of combined application of 80% conventional fertilizer of nitrogen and nano-carbon at 0.6%was equal to that with supplied 100% conventional fertilizer (control). This indicated that the utilization rate of nitrogen fertilizer was increased after combined application of nano-carbon, which can save the N fertilizer amounts in production practice.
