demographic analyses of dubas bug, ommatissus lybicus de bergevin, (hemiptera: tropiduchidae), reared on five date palm varieties (zahdi, mazafati, piarom, khasi, and shahani) were constructed under laboratory conditions at 27±1ºc, 70±5% rh, and a 14:10 hours (l: d) photoperiod. data were analyzed based on the age-stage, two-sex life table theory to take the variable developmental rate among in...

The objective of the study was to analyze chemical structure of date palm (Phoenix dactylifera L.) by employing ultimate, proximate and thermo-gravimetric techniques. Samples from different anatomical parts of date palm, namely trunk, frond base, frond midrib, leaflets, coir, fruit stem, date stone, and fruit empty bunches were considered for the experiments. Based on the findings in this work ...

the effect of feeding silage of leaf and stem of banana tree with waste date palm on feed intake, microbial protein synthesis and blood parameters using four adult rams in a change- over design with four 21-days period were examined. eighty five kg leaf and stem of banana tree with 15 kg of waste date palm were mixed together and ensiled for 45 days. chemical composition and sensory evaluation ...

an efficient method for producing doubled haploid plants of date palm ( phoenix dactylifera l.) was established using in vitro colchicine treatment of anthers. to this study male inflorescences were harvested in the appropriate developmental stage. separated anthers after one day cold (4°c) pretreatment, in uninucleate stage of microspore were transferred to the modified y 3 medium containing d...

Microsatellite markers containing simple sequence repeats (SSRs) are a valuable tool for genetic analysis. Our objective was to identify microsatellite markers that could be used to differentiate between male and female date palm (Phoenix dactylifera). The date palm is a dioecious plant whose sex cannot be determined until it reaches a reproductive age between 5 and 10 years. An early selection...
