THE ELASTICITY CHARACTERISTICS OF PALM DATE

Al-Ayedh: Rearing the Red Date Palm Weevil 353 EVALUATION OF DATE PALM CULTIVARS FOR REARING THE RED DATE PALM WEEVIL, RHYNCHOPHORUS FERRUGINEUS (COLEOPTERA: CURCULIONIDAE)

Development of red date palm weevil Rhynchophorus ferrugineus (Olivier) was evaluated on 4 popular cultivars of date palm, viz., ‘Khalas’, ‘Sukkary’, ‘Khasab’, and ‘Sillaj’ for 2 consecutive generations. The weevils reared on ‘Sukkary’ showed significantly better growth expressed in most parameters such as length, width and weight at larval, pupal and adult stages. Significantly greater numbers...

Genetic Stability of Micropropagated Plantlets in Date Palm

Randomly amplified polymorphic DNA (RAPD) markers were used to analyze genetic stability of the somatic embryogenesis-derived regenerants (R1-6) and mother plant in Iranian date palm (Phoenix dactylifera L.) cultivar Khanizi. Total genomic DNA extracted from in vitro fresh leaves of regenerated plants and mother plant was amplified using 10-mer oligonucleotide Fermantas primers. Four primers of...

Palm Date Fibers: Analysis and Enzymatic Hydrolysis

Waste palm dates were subjected to analysis for composition and enzymatic hydrolysis of their flesh fibers. The fruit contained 32% glucose and 30% fructose, while the water-insoluble fibers of its flesh consisted of 49.9% lignin and 20.9% polysaccharides. Water-insoluble fibers were settled to 55% of its initial volume in 12 h. The presence of skin and flesh colloidal fibers results in high vi...

Investigating signal propagation and strength distribution characteristics of wireless sensor networks in date palm orchards

To efficiently plan and deploy wireless sensor networks in palm orchards, it is crucial to obtain preliminary knowledge of radio signal propagation and strength distribution characteristics. Various received signal strength indicator (RSSI) measurements were taken with antennas, operating with a 2.4-GHz band and located 0.05 m away from trunks. The RSSI measurements, at seven different antenna ...
