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, 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...

In this study fourteen microsatellite primer pairs were used to study the genetic diversity of Shishi Date palm in Qatar. A total of 32 date palm (15 Shishi cultivar, 10 Khalas and seven male date palms) were collected from Qatar and 5 Shihi cultivars were collected from Saudi Arabia ‎for comparison. The Shishi set collected from Qatar was selected from ‎different regions to represent the ‎gene...

Date palm (Phoenix dactylifera L.) is a monocot, dioecious and high longevity tropical plant greatly considered due to its high economic importance in Middle East. This investigation was carried out to detect genetic relations among 34 cultivars of Iranian date palm, both males and females, using ISSR markers. Accordingly, total DNA was extracted using CTAB method and was subjected to PCR ampli...

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...

gasification is a well-known reaction owing to its relevance to generation of sustainable energyfrom biomass and development of porous carbons. the present paper attempts to experimentally investigate the kinetics of palm shell char gasification using carbon dioxide (co2) in a controlled environment using thermo gravimetric analyzer (tga) at temperatures ranging from 800 to1000°c. a relevant ki...

active carbon is char derived from pyrolysis of organic materials. it has a high porosity level and is used to filter fluids. many types of agricultural materials are used to produce active carbon. the trunk of the date palm, with its low density and high porosity, has great potential for producing active carbon. in this research, the bark was pyrolyzed at 450°c for 60 min to produce active car...
