In this research NaOH treated date palm fibres were used as reinforcement in phenolic based composites. The composites prepared by hot press technique and evaluated tensile flexural, structural, thermo gravimetric dynamic mechanical properties. Overall properties of modification/treatment fibers’ surface enhanced, that have been studied compared to untreated samples. samples 50% DPF showed high...
Date palm tissue culture technique aimed to production of huge numbers of plants to farmers in order to increasing dates which have high nutritional value. Date palm plantlets from pre-acclimatization stage in vitro were transferred to acclimatize in the greenhouse cultured in peat moss + perlite 2:1 and kept in the plastic covered inside 100% humidity and 28 C0 till new leave or root was grown...
Differential plant damage due to litterfall in palm-dominated forest stands in a Central Pacic atoll
High densities of palms are common in many tropical forests. In some cases, the dominance of palms has been associated with a depauperate understorey and high rates of native seedling mortality. A variety of different potential mechanisms has been suggested to explain the sustained palm dominance in the understorey and canopy of these forests. Working in a Cocos nucifera-dominated wet tropical ...
In the current study, the effect of spoilage date palm (Phoenix dactylifera L.) fruit juice and molasses on Pacific white shrimp (Litopenaeus vannamei) cultured in a biofloc technology (BFT) surveyed. Four bioflocs were managed: BFT fed diets of 25% CP and palm juice (P25), diets of 25% CP and Molasses (M25), diets of 15% CP and palm juice (P15), diets of 15% CP and Molasses (M15) and clear wat...
in the last decade, frequency of late cold incidence has increased in the upland forest nurseries. the aim of present study was to reduce the damage caused by spring frost and to increase the efficiency of persian maple seedlings production in mountain nurseries. this study was conducted as split plot design with two main treatments and three replications in two consecutive years (2009-2010) in...
The date palm can adapt to extreme drought, to heat, and to relatively high levels of soil salinity. However, excessive amounts of salt due to irrigation with brackish water lead to a significant reduction in the productivity of the fruits as well as marked decrease in the viable numbers of the date palm trees. It is imperative that the nature of the existing salt-adaptation mechanism be unders...
