This paper describes an investigation on the use of a new composite construction material composed of plaster, sand, crushed gravel and date palm fibres of waste agriculture peels, having mechanical properties potentially useful in technical domains. Thermal conductivity and some mechanical and physical properties are investigated. The results showed that the incorporated vegetable fibres chang...
Phoenix dactylifera belongs to the Arecaceae family; its leaves, barks, pits, fruits and pollens have antioxidant, anticancer, hepatoprotective, n europrotective, nephroprotective, gastrointestinal protective, antidiabetic, antihyperlipidemic, sexual improvement and antimicrobial potentials. The broad pharmacological effects of P. dactylifera may be attributed to the powerful and beneficial ing...
Date palm (Phoenix dactylifera L.) is a cultivated woody plant species with agricultural and economic importance. Here we report a genome assembly for an elite variety (Khalas), which is 605.4 Mb in size and covers >90% of the genome (~671 Mb) and >96% of its genes (~41,660 genes). Genomic sequence analysis demonstrates that P. dactylifera experienced a clear genome-wide duplication after eithe...
The genetic diversity in the date palm germplasm of 59 female accessions representing 12 cultivars from different locations in Qatar was investigated using 14 loci of simple-sequence repeat (SSR) primers. A total of 94 alleles, with a mean of 6.7 alleles per locus, were scored. The number of alleles per locus varied from 3 (primer mPdCIR090) to 11 (primers mPdCIR010 and mPdCIR015). The amplifie...
We have analysed the mycobiota of date palm (Phoenix dactylifera, L.) leaves using several techniques. Profusely sporulating fungi (Penicillium spp. and Cladosporium spp.) developed when plating leaf fragments and leaf washings. Fusarium oxysporum, was particularly abundant in leaves infested with the red scale insect Phoenicococcus marlatti Cockerell, 1899, but an undescribed Lecanicillium cf....

Molecular typing of 377 female date palm trees belonging to 18 Libyan cultivars and representing common genotypes in the central Libyan oasis of Al Jufrah was performed using 16 highly polymorphic microsatellite or SSR loci. A total of 110 alleles with an average of 6.88 alleles per locus were scored indicating the high level of polymorphism existing among the cultivars thus allowing their gene...
Cryopreservation is the technology of choice not only for plant genetic resource preservation but also for virus eradication and for the efficient management of large-scale micropropagation. In this chapter, we describe three cryopreservation protocols (standard vitrification, droplet vitrification, and encapsulation vitrification) for date palm highly proliferating meristems that are initiated...
Column chromatography of the Egyptian date palm pollen, resulted in the isolation of estradiol, estrone among ten compounds from the hexane fraction. Also, besides rutin, additional four flavonoids from the ethyl acetate extract were isolated. HPLC analysis of the hexane fraction (using RFBDS C18 – isocratic acetonitrile /water 58:42) revealed the presence of estrone, estradiol and estriol comp...
the genus phoenix is one of the most widely cultivated groups of palms around the world. the aim of this study was to determine the antioxidant activity and total phenolic compounds of 14 different varieties of date palm (phoenix dactylifera l., arecaceae) seed extracts with 5 solvents [water, methanol, methanol (50%), dmso, and water: methanol: acetone: formic acid (20:40:40:0.1)]. ferric redu...
