the present study was undertaken to investigate and optimize the possibility of xanthan gum production by xanthomonas campestris ptcc1473 in 500ml shake flasks on the second grade date palm. using an experimental response surface methodology (rsm) coupled with a central composite design (ccd), three major independent variables (nitrogen source, phosphor source and agitation rate) were evaluated...

date bunch fading disorder (dbfd) has been one of the major issues facing date palm growers in recent decades. this order has caused high and non-compensable losses to date palm product. despite numerous studies, predominantly focusing on the causes and mitigation methods of this disorder, no precise influencing factors have been established and practices which can completely control it are not...

Background & Aims: Date palm fruit is one of the highly consumed foods with antioxidant compounds and high nutritive value in Iran. In this study, total phenolic compounds and antioxidant capacity of three varieties of date palm (Hajmohamadi, Kabkab, and Khasi) in three stages of ripening were investigated. Methods: This was a laboratory study. Palm fruits of Hajmohamadi, Kabkab, and Khasi vari...

mycorrhizal symbiosis increase nutrient uptake and enhance plant growth by elaborating root system. the positive effects of mycorrhizal symbiosis on the growth, physiology and ecology of various plants have been recognized. the symbiotic relations between mycorrhizal fungi and date palm with regard to nutrient uptake by this plant have not yet been explored and studied in iran. this project was...

Red palm weevil (RPW) is widely considered a key pest of palms, creating extensive damages to the date trunk that inevitably leads death if no eradication done. This study evaluates potential remote sensing approach for timely and reliable detection RPW infestation on canopy. For two consecutive years, an experimental field with infested control palms was regularly monitored by Unmanned Aerial ...

Although date palm is relatively salt-tolerant, little is known about the underlying molecular mechanisms that contribute to its salt tolerance. Only recently, investigators have uncovered microRNA-mediated post-transcriptional gene regulation, which is critical for typical plant development and adaptation to stress conditions such as salinity. To identify conserved and novel miRNAs in date pal...

There are pressing concerns about the interplay between agricultural productivity, water demand, and water availability in semi-arid to arid regions of the world. Currently, irrigated agriculture is the dominant water user in these regions and is estimated to consume approximately 80% of the world’s diverted freshwater resources. We develop an improved irrigated land-use mapping algorithm that ...

In this research NaOH treated date palm fibres were used as reinforcement in phenolic based composites. The composites prepared by hot press technique and evaluated tensile flexural, structural, thermo gravimetric dynamic mechanical properties. Overall properties of modification/treatment fibers’ surface enhanced, that have been studied compared to untreated samples. samples 50% DPF showed high...

Microsatellite markers containing simple sequence repeats (SSRs) are a valuable tool for genetic analysis. Date palm is a dioecious and slow flowering and is very difficult to identify the gender of the trees until it reaches the reproductive age (5-10 years). A total of 12 microsatellite primers were used with 30 date palm samples, 14 parents (8 male + 6 females) and 16 progeny (developed from...
