Behavior of Barhee date palm cultivar produced by using tissue culture technique and grown in different regions of upper Egypt

Abstract

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.
