Many Phoenix dactylifera (date palm) cultivars are grown in the arid and semiarid regions of the world, including Saudi Arabia. P. dactylifera is highly tolerant to salinity stress. To investigate the response of Khalas cultivar of P. dactylifera, two-month-old plants were treated with sodium chloride (50, 100, and 150 mM NaCl) for three months. Our result showed that proline content was higher...

Proline accumulation is a common biochemical indicator for assessing environmental stress in plants. The objective of this study was to determine the effect of various doses of two types of magnetic fields on date palm (Phoenix dactylifera L. (cv. Khalas) seedlings based on proline accumulation. The first type involved static magnetic field (SMF) generated by an electromagnetic circuit set at 1...

This study was conducted to examine the effect of low doses of X-rays on date palm (Phoenix dactylifera L., cv. Khalas) seed germination and seedling growth. A significant reduction in seed germination was observed in response to X-irradiation as compared to the non-irradiated control. A significant reduction in seed germination percentage (82.85%) began at 0.25 Gy of X-rays and persisted to de...

Based on next-generation sequencing data, we assembled the mitochondrial (mt) genome of date palm (Phoenix dactylifera L.) into a circular molecule of 715,001 bp in length. The mt genome of P. dactylifera encodes 38 proteins, 30 tRNAs, and 3 ribosomal RNAs, which constitute a gene content of 6.5% (46,770 bp) over the full length. The rest, 93.5% of the genome sequence, is comprised of cp (chlor...

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...

This study aimed to maximize the utilization of date palm residues and convert them into an environmentally friendly form fuel. The variety Khalas (leaf fronds whole fronds) were used produce fuel briquettes at three moisture contents (8, 10, 12%) four storage times (0, 15, 30, 45 days). mechanical, fuel, quality properties these investigated. results showed that leaf had best in terms mechanic...

The date palm mite (DPM), Oligonychus afrasiaticus (McGregor), is a key pest of unripe fruits. detection this depends largely on the visual observations webs it produces green One most important problems DPM control lack an accurate decision-making approach for monitoring and predicting infestation Therefore, study aimed to develop, evaluate, validate prediction models fruits based meteorologic...

One of the technological advancements in agricultural production is tissue culture propagation technique, commonly used for mass multiplication and disease-free plants. The necessity date palm emerged from inability traditional methods’ offshoots to meet immediate demands significant amounts planting material commercial cultivars. Tissue plantlets are produced a protected aseptic vitro environm...

Climate change affects fruit crops’ growth and development by delaying ripening, reducing color development, lowering quality yield. The irregular date palm ripening in the past few years is assumed to be related climatic change. current study aimed design validate an automated sensor-based artificial system (S-BARS) combined with ultrasound pretreatment for fruits cv. Khalas. A control was con...

Applications of modern micro-irrigation methods are inevitable for optimum water use due to the limitations imposed by irrigation resource scarcity. Regardless shortages and associated challenges in dry areas, date palm trees consumes an excessive quantity annually using conventional methods. Therefore, present study was designed evaluate effects surface subsurface systems, i.e., drip (SSDI), c...
