The date palm (Phoenix dactylifera) is considered the main agricultural crop in many dry regions of the world, including the United Arab Emirates (UAE). It has been demonstrated that the date palm forms a beneficial symbiotic association with arbuscular mycorrhizal (AM) fungi. AM fungi are known to improve plant growth, increase nutrient uptake and assist plant growth under biotic and abiotic stress conditions. The main aim of the present study was to evaluate the efficiency at which an isolate of the AM fungus Rhizoglomus intraradices improves the vegetative growth and nutrient content of two date palm varieties in the UAE, namely Khalas and Khenaizi. R. intraradices was isolated from a farm near Abu Dhabi and propagated in the labs of the UAEU. In vitro micropropagation date palm plantlets were subjected to three treatments under greenhouse conditions (T1: Control. T2: Microbial Wash. T3: R. intraradices). The inoculated date palm varieties showed an increase in plant growth parameters such as shoot and root fresh weight and chlorophyll a and b contents and improvement in the uptake of P and some other micronutrients. The results showed that R. intraradices has the potential to be used in the sustainable production of micro propagated date palms. Future studies are needed to highlight the function and the role of the new fungus isolate under different treatments and environmental conditions in the UAE.
