developing a rapid, nondestructive and reliable method to measure moisture content of date fruit is of interest in pre- and post-harvest processes of this valuable product. throughout this research, by putting date palm fruits (cv. mazafati) in a parallel plate capacitor, the sinusoidal alternative voltage in the frequency range of 1 to 100 mhz was exerted to the dates and the response of the c...

Phyllotaxis is the study of the morphological order of plants. Remarkably, in spite of the overwhelming diversity of plant morphology, there are common patterns that link a wide variety of species. The date palm, having a phyllotactic order, possesses a simple, repetitive model. Only a small number of parameters are needed to represent the phyllotactic order of the date palm. This a priori know...

Global climate model outputs involve uncertainties in prediction, which could be reduced by identifying agreements between the output results of different models, covering all assumptions included in each. Fusarium oxysporum f.sp. is an invasive pathogen that poses risk to date palm cultivation, among other crops. Therefore, in this study, the future distribution of invasive Fusarium oxysporum ...

Date palm cultivars differently tolerate salinity and drought stress. This study was carried out to study the response of date palm to severe salinity and drought based on leaf proteome analysis. Eighteen-month-old date palm plants were subjected to severe salt (48 g/L NaCl) and drought (82.5 g/L PEG or no irrigation) conditions for one month. Using a protein 2D electrophoresis method, 55 prote...

Helminthosporium (Bipolaris) causes a leaf spot disease in Chrysalidocarpus lutescens (cane palm) in Sri Lanka. The losses could reach 90% of production during rainy weather conditions. Field experiments were carried out to test the efficacy of treatment of seeds of C. lutescens against Helminthosporium infection. In the fungal growth tests the isolates T.harzianum 1, T.harzianum 2, T.viride 1,...

this study was carried out to investigate the morphological and anatomical aspects of somatic embryogenesis in date palm. lateral bud and shoot tip explants excised from young offshoots were cultured on ms medium with 2,4-d. somatic embryogenesis was in-duced by transferring the calli produced on the same medium without hormones. micro-tome sectioning of paraffin-embedded specimens was carried ...

Oryctes agamemnon (Burmeister 1847) (Coleoptera, Scarabaeidae) was accidentally introduced in the southwestern oases of Tunisia (Tozeur) around 1980 and spread to the Rjim Maatoug region. In these areas O. agamemnon was specific to date palm trees causing severe damage that can result in potential danger due to collapse of the tree. This study was conducted from April 2004 to March 2006 in 4 si...

The fruit of date palm (Phoenix dactylifera L.) is an important horticultural product in the Middle East and North Africa. Among more than 400 reported date palm cultivars in Iran, around 20 cultivars are more important due to having better eating quality and trading values. In this study, the fruit of nine commercially important date cultivars including ‘Barhee’, ‘Breim’, ‘Deiri’, ‘Fersi’, ‘Ga...

Transposable elements (TEs) are mobile genetic elements present in almost all eukaryotic genomes. Due to their typical patterns of repetition, discovery, and characterization, they demand analysis by various bioinformatics software. Probably, as a result of the need for a complex analysis, many genomes publicly available do not have these elements annotated yet. In this study, a de novo and hom...
