“…Boron, zinc and calcium were highly effective in improving, nutritional status yield and fruit quality of pomegranate trees. Foliar application of some micronutrients such as Fe, B, Mn and Zn increased fruit yield and reduced the percentage of cracked fruits (Bambal et al, 1991;Bahadur et al, 1998 andMasoud et al, 2018).…”

This study was carried out at the Experimental Orchard, Faculty of Agriculture, Assiut University, Egypt, to study the effect of Gibberellic Acid (GA 3), Naphthalenacetic acid (NAA), calcium chloride and zinc sulphate spraying on fruiting of Manfalouty pomegranate during 2017 and 2018 seasons. The experiment was set up in a complete randomized block design with three replicates, one tree per each. GA 3 , NAA, calcium chloride (CaCl 2) and zinc sulphate (ZnSO 4) spraying significantly increased the yield/ tree compared to unsprayed ones. GA 3 spraying gave the highest yield followed by calcium chloride. On the other hand, all treatments significantly decreased the fruit cracking percentage compared to unsprayed ones. The least fruit cracking was recorded due to calcium chloride spraying. All treatments significantly increased fruit weight and fruit dimensions as well as pulp percentage and juice contents compared to unsprayed ones. Moreover, calcium chloride and zinc sulphate as well as combination of GA 3 or NAA with them significantly improved the fruit chemical constituents, whereas, GA 3 spraying alone decreased the chemical fruit constituents compared to unsprayed ones. It could be concluded that spraying Manfalouty pomegranate trees with calcium chloride (CaCl 2) at 2% and zinc sulphate at 0.025% plus GA 3 at 50 ppm or NAA 25 ppm thrice was necessary to get high yield, reduce the fruit cracking percentage and improve fruit quality.

“…Spraying loquat trees with K 2 Si 2 O 5 at 1 or 2% improved the percentages of fruit retention, fruit weight, number of fruits per cluster and thus the final yield 43 . K 2 Si 2 O 5 sprayed at 5000 ppm enhanced the fruit weight, depleted the fruit cracking with improving the yield in ‘Wonderful’ 97 and ‘Manfalouty’ pomegranates 98 with the respect of untreated trees. Spraying of “Washington Navel” orange trees (by 0.1, 0.2 and 0.3% K 2 Si 2 O 5 enhanced clearly number of fruits per tree, fruit weight, thus consequently the fruit yield 89 .…”

The current study was performed on 8 years old "Succary" pomegranate cultivar (Punica granatum L.) during the 2019 and 2020 seasons. One hundred pomegranate trees were chosen and sprayed three times at the beginning of flowering, full bloom, and 1 month later with the following treatments: water as control, 0.025, 0.05 and 0.1 mg/L Se; 5 mL/L, 7.5 and 10 mL/L Ag NPs, and 0.5, 1 and 2 mg/L K2Si2O5. The results showed that spraying of SE, Ag NPs, and K2Si2O5 ameliorated the shoot length, diameter, leaf chlorophyll content, set of fruiting percentage, and fruit yield per tree and hectare compared to control through studying seasons. Moreover, they improved the fruit weight, length, and diameter, as well as total soluble solids, total, reduced, and non-reduced sugars percent, while they lessened the juice acidity percentage compared to control. The most obvious results were noticed with Se at 0.1 mg/L, Ag NPs at 10 mL/L, and K2Si2O5 and K2Si2O5 in both experimental seasons over the other applied treatments. By HPLC analysis, peel extracts showed the presence of several bioactive compounds of catechol, syringic acid, p-coumaric acid, benzoic acid, caffeic acid, pyrogallol, gallic acid, ferulic acid, salicylic acid, cinnamic acid, and ellagic acid. The extracts applied to Melia azedarach wood showed promising antifungal activity against Rhizoctonia solani and were considered wood-biofingicides.

Pomegranate (Punica granatum L.) fruit quality depends on many traits including visual, biochemical and mineral characteristics. One of the negative traits is aril whitening (AW) which is a frequently observed disorder in hot and dry climates, that leads to decline in desirable fruit quality. Color, antioxidant, and mineral contents of the arils are of prime importance as quality traits. Therefore, this study aims to investigate the effect of shading and foliar minerals on fruit quality during the fruit development stages of pomegranate. Treatments included shaded (50% green net) and unshaded trees and foliar application of trees with potassium sulfate (K, 1% and 2%) or sodium silicate (Si, 0.05, 0.1 and 0.15%) during two growing seasons. Results showed that the severity of AW at harvest decreased significantly when trees were covered with shading compared to control. The color values of L* and ⁰hue for arils were lower in fruits grown under shading conditions indicating darker red arils. Shading significantly reduced chilling injury in cold storage compared to open field fruits. Shading and Si 0.15% increased superoxide dismutase, and catalase enzymes activity while decreased Polyphenol oxidase and peroxidase. Covering trees with shading and Si 0.15% spray resulted in the highest total anthocyanin, antioxidant activity, and total phenolics content in the arils. Shading as well as Si 0.15% increased macronutrients content of the arils. The study concluded that covering pomegranate trees and spraying with Si in hot climate reduced AW, increased antioxidant traits, and led to higher fruit quality.
