This study was conducted during 2017 and 2018 seasons on Barhee date palm cv. (Phoenix dactylifera L.) at the age of 18 years, grown in three regions of Upper Egypt i.e Matana, Luxor Governorate; Kom-Ombo and Toshka, Aswan Governorate to evaluate its vegetative properties as well as physical properties and determination chemical composition of fruits. The obtained results revealed that, there were significant differences between the vegetative characteristics of date palm Barhee cv. because of different weather conditions of locations conducted study. The palms grown in Matana region recorded the largest values of the palm girth, number of leaves, length of the leaf and leaflet, leaflet area, spines number and area, while the lowest values of these parameters were obtained the palms grown in Toshka region. There are significant differences between the yield components because of growing Barhee in the three regions of Upper Egypt. There were significant differences of both physical and chemical fruits properties harvested from different regions of study. Barhee in Kom-Omboregion recorded the largest values of fruit length, fruit shape index, fruit weight, specific gravity of fruit, weight and percentage of flesh in the two study seasons. The highest values of TSS percentages, total and reducing sugars, Nitrogen, Phosphorus and Potassium content and lowest tannins content. The highest values of non-reducing sugars, the highest moisture content, and the lowest acidity were obtained in the case of Barhee in Toshka region. Generally, the productivity and quality of Barhee palm could be arranged discerningly as follows: Kom-Ombo, Matana and Toshka.
Using floral buds could help to conserve the date palm biodiversity and finding a way to rapidly multiply the landraces with socioeconomic value. Siwa oasis in Egypt can be considered as biodiversity center of date palm. Several competitive date palms emerged from seeds, a variety at risk of distinction named "Ghazal" and top commercial variety 'Siwy' were selected based on fruit phenotype and evaluated. Upon flowering an immature spathe was technically excised from each parent tree and transferred to the laboratory for micropropagation. The in vitro plantlets of these endangered and superior genotypes were obtained within a single year. The steps carried out to achieve this target were described and discussed in the current study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
