Hydroponics culture have many advantages such as increased yield, health and uniform product, conservation of water and land , better protect , control of environmental pollution and reduce of workers for cultivation. So in recently years, usage of organic and inorganic substrates obtained more important for greenhouse owners and researchers. The aim of this study was Effects of culture substra...

Date palm, the most important tree in Saudi Arabia and Middle East, produces a huge amount of waste yearly form fibrous materials, dried fruits, seeds. Such is great source excellent degradable biomass that can be used numerous applications as natural fiber composites, active carbon precursors, even nano-featured sheets. That rich resource burned on date palm farms due to lack effective process...

The old world date mite, Oligonychus afrasiaticus (McGregor) (Acari: Tetranychidae) is a severe spider mite pest of date palm in most of the Middle East and North Africa. Considering that nothing is known about the performance of phytoseiid predators against O. afrasiaticus, biology, predation, and life table parameters of Cydnoseius negevi (Swirski and Amitai) and Neoseiulus barkeri Hughes (Ac...

Date palm, phoenix dactylifera l. (arecales: arecaeae) is the most important crop of the arabian Peninsula. the Kingdom of Saudi arabia is among the top 3 date producing countries of the world estimated to have over 400 date palm cultivars of which 25 are important and yield 1.3 million tons of dates annually. the red palm weevil (RPW) Rhynchophorus ferrugineus (olivier) (Coleoptera: Curculioni...

Adult Rhynchophorus ferrugineus (Olivier) captured in pheromone-baited traps in commercial date palm orchards in the Al Ahsaa Directorate, Kingdom of Saudi Arabia, were used in computerized flight mill studies to determine the flight characteristics of this highly invasive and destructive palm pest. Flight mill studies were run at three different time periods, winter (December), spring (March),...

Analytical methods are required in addition to administrative controls to verify the geographical origin of vegetable oils such as palm oil in an objective manner. In this study the application of fatty acid and volatile organic compound fingerprinting in combination with chemometrics have been applied to verify the geographical origin of crude palm oil (continental scale). For this purpose 94 ...

During the last two decades Red Palm Weevil (RPW, Rynchophorus Ferrugineus) has become one of the most dangerous threats to palm trees in many parts of the World. Its early detection is difficult, since palm trees do not show visual evidence of infection until it is too late for them to recover. For this reason the development of efficient early detection mechanisms is a critical element of RPW...

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...
