to determine the effects of different pollen types and suitable pollination time in medjhol date palm, an experiment was carried out with three pollen cultivars: ghaname, vardy and samesmave and two pollination times (1-3 days before or after spathe opening) during 2010-2011 in date palm and tropical fruit research institute in ahwaz. the results showed that the vardy pollen had the most signif...

The focus of this study was to develop a method demonstrate the feasibility obtaining useful and high-value resources from Phoenix dactylifera residues and, determine physical chemical properties ash dates-palm-tree remains. Date-palm leaves fiber samples were combusted for 50 s, using an Nd: YAG laser with 40 W output power. It found, that combustion one gram agricultural waste could be comple...

The date palm bunch fading disorder/disease is one of the greatest challenges faced by date palm growers. In the present study, the effect of appropriate orchard management on some qualitative and quantitative features of date palm bunch was studied. For this purpose, two orchards of cv ‘Kabkab’ with a history of previous incidence were selected in two districts of Bushehr province; Tangestan a...

Background: In Algeria, date palm is currently confronted to the Bayoud disease. Biotechnological tools such as protoplasts fusion can appear as an alternative to ensure rapid multiplication and improvement of this species. Objectives: Callogenesis induction in protoplasts isolated from embryogenic callus of three date palm cultivars. Materials and Methods: Some factors influencing the isolatio...

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...

The main objective of this research was to study the influence an enzymatic treatment process date palm fibers on their chemical and morphological properties as well physical mechanical characteristics composites filled with raw treated fibers. To end, three extraction approaches were considered (a combination xylanase pectinase enzymes, enzymes followed by a one enzyme xylanase). Chemical anal...

The selection of adequate substrate for soilless culture is based on technical and economic considerations. Therefore, the search alternatives by valorization natural by-products gaining importance. main objective this study was to compare effects local farm resources, date-palm waste, as substrate, coconut fiber (CF) (commonly used in culture) melon (Cucumis melo L.) plant growth, water relati...

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...

The aim of the present work was to investigate the chemical composition, mineral extractability, and antioxidant capacity of six date palm varieties grown in Sudan. The results showed that Sudanese date varieties contained significantly different (P < 0.05) amounts of moisture, ash, fiber, oil, and carbohydrates, but have almost similar amounts of protein. Moreover, results revealed that date v...
