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...

Viability of fresh and stored pollen of date palm (Phoenix dactyllf.,.., L) was studied. Pollen samples were stored at room temperat. ture (25-30°C), under refrigeration (3-4°C)t..ln vivo test, pollen viability was determined'by percent fruit set. Results suggest that different storage conditions had no apparent effect on pollen viability as tested with acetoearmine. However, results of in vivo...

UNLABELLED PREMISE OF THE STUDY To complement existing sets of primarily dinucleotide microsatellite loci from noncoding sequences of date palm, we developed primers for tri- and hexanucleotide microsatellite loci identified within genes. Due to their conserved genomic locations, the primers should be useful in other palm taxa, and their utility was tested in seven other Phoenix species and ...

Abstract Dry leaves of date palms (DPs) are by-products cultivation that often mismanaged in oasis agroecosystems. Ideally, they should be upcycled a circular agriculture model before producing and exporting high-value products. Compost inputs enhance soil organic matter conserve soil. This study investigated composting four mixtures based on farming system requirements the availability resourc...
