Date palm (Phoenix dactylifera L.) is among the earliest fruit crops cultivated in the arid Arab Peninsula, North Africa, and Middle East territories. Dates are a significant source of food and revenue for Middle East and North Africa's local communities. It has distinctive features of biology and development that require special methods of reproduction, culture and governance. In varying date-growing regions, there are thousands of date plant cultivars and varieties. The lengthy life cycle, long juvenile lifespan, and date palm dioecism produce cultivation difficult. Every year, the percentage of crop genomes sequenced has continued to increase. The incredible rate at which DNA samples become accessible is mainly due to the enhancement in cost-and speed-related sequencing techniques. Modern sequencing techniques enable the sequencing at realistic price of various cultivars of tiny plant genomes. Although many of the published genomes are deemed incomplete, they have nevertheless proven to be useful instruments for understanding significant plant characteristics such as fruit maturation, grain characteristics and adaptation of flowering time, here we review date palm genomic studies and determine its genomics element.

This paper was studying the effects of palm tree wastes on the behavior of the concrete to reduce cement content in the concrete to ensure a sustainable environment. Both fibers of palm tree and the ash of palm tree leaves are used in this study considering different percentages of palm tree wastes, which are replaced the cement, to investigate both of workability and strength of the concrete. Also, the combination of palm tree leaves ash and fibers of palm trees is investigated. The slump and compression tests are carried out to evaluate both workability and concrete strength. The palm fibers were reducing the workability of concrete at both of different percentage of replacement and different fiber lengths. The slump is reduced by 26.667% at 2 cm fibers length and it is completely lost at 5 cm length fibers at the same percentage of replacement of 5% of the cement content. The palm fibers were weakening concrete compressive strength at different percentages and different fiber lengths. Palm leaves ash was enhancing concrete workability and concrete compressive strength.

Purpose Industrialization is leading to gradual accumulation of heavy metals in the date palm fruits and ecosystem. This paper aims at estimating the bioaccumulation of  heavy metals in soils, fruits (dates) near the industrial area of Al-Rusail in the Sultanate of Oman. There were three sites located for sampling and each with three farms except site 3 with one farm; industrial site, cement factory and control farm. The soil, water and date palm fruits were analyzed for heavy metals concentration using inductively coupled plasma optical emission spectrometer. The results of  analysis showed that the mean concentration of heavy metals in soil was in the following order: Ni> Zn > Pb > Cd. The concentration of heavy metals in the groundwater was found to be in this order Zn > Ni> Pb> Cd, and Zn> Pb > Ni > Cd in fruits. The statistical interaction of heavy metal mean concentrations indicated cadmium with the highest mean (0.007117mg/kg) in Farm 1 during the month of June at 0-30cm (mg/kg) in soil under Industrial sites. The fruit stages differ statistically with the highest concentration of zinc ranging from 0.190517 mg/Kg of khalal stage of farm 1 to the 0.03127 mg/kg of the control farm. groundwater heavy metal concentration was very low across the farms with the least (Cd at 0.0002434mg/Kg) in control site and not statistically different from other sites' farms.In general, the research indicated an increases in the heavy metal concentrations with closeness to industrial sites.
