This study is focused on the internal structure of leaf midrib (rachis) of some male tress of certain date palm cultivars, namely Khalas, Naboat-Saif, Sillej and Sukkary, common to Saudi Arabia. It takes into consideration the structure, dimension and abundance of vascular bundles (VBs), vessel lumen diameter, relative proportion of fibers and vess...

Summary of my paper article Article ((Effect of Date Palm Cultivar, Particle Size, Panel Density and Hot Water Extraction on Particleboard Manufactured from Date Palm Fronds )) Agriculture 2015, 5, 267-285; doi:10.3390/agriculture5020267

The objective of this work was to evaluate some of the important physical and mechanical properties of particleboard panels manufactured from three different cultivars of date palm (Phoenix dactylifera) fronds, namely Saqui, Barhi and Sukkari. Experimental panels were manufactured from hot water extracted and non-extracted, and fine and coarse part...

English Summary Date palm (phoenix dactylifera) is a perennial with an average life of 150 years. There are approximately 62 million trees in the Middle East and North Africa. Each year the trees are pruned to remove old dead or broken leaves. This produces approximately 100, 000 tons of date palm fronds and 15, 000 tons of date palm leaves in Saud...

The objective of this work was to evaluate some of the important physical and mechanical properties of experimental oriented strandboard panels manufactured from four different cultivars of date palm (Phoenix dactylifera) fronds. Currently date fronds are considered as waste and under-utilized. Open burning and landfill are common practices for suc...

Plants are able to extract metal(loid) contaminants from the soil or water through their roots and translocate them to harvestable aerial shoots. Of late, this plant potential has been used as a phytotechnology, termed as phytoextraction, for cleaning the contaminated sites, and has successfully removed elements like As, Cd, Cu, Ni and Pb, among ot...

This study, undertaken in the Riyadh region of Saudi Arabia, was focused on high initial density plantation and the subsequent thinning of Acacia salicina trees, to ensure high individual tree growth suitable for saw timber production. It investigated the effect of high stand density on restricting early branch development. Trees were planted in 19...

This study, based on a high initial-density plantation of Acacia salicina trees, which was later thinned to facilitate high individual-tree growth suitable for saw-timber production, investigates the effect of thinning on some wood quality parameters. Trees were planted in 1998, at a density of 6400 trees ha-1 (with spacing of 1.25 x 1.25 m). Annua...

This study, based on a high initial-density plantation of Acacia salkina trees, which was later thinned to facilitate high individual-tree growth suitable for saw-timber production, investigates the effect of thinning on some wood quality parameters. Trees were planted in 1998, at a density of 6400 trees ha-1 (with spacing of 1.25 × 1.25 m). Annual...

The study was conducted to determine the age structure, regeneration status and possible factors for regeneration-gap of Ziziphus population of the southwestern valleys of Saudi Arabia. The population age structure was determined through stem disc ring analysis of fallen trees and girth value measurements of live trees. The average number of rings...

Beekeeping plays an important role in increasing and diversifying the incomes of many rural communities in Kingdom of Saudi Arabia. However, despite the region's relatively good rainfall, which results in better forage conditions, bees and beekeepers are greatly affected by seasonal shortages of bee forage. Because of these shortages, beekeepers mu...

Three fast-growing trees, namely Acacia saligna, Conocarpus erectus, and Melia azedarach, as well as date palm (Phoenix dactylifera) midribs, were evaluated for their suitability for particleboard production. Panels were pressed at two target density levels of 750 and 650 kg/m 3 and a thickness of 13 mm using 10 percent urea-formaldehyde resin. Mod...

Air pollution caused by the combustion of coal at the Badarpur Thermal Power Plants, New Delhi, had a bearing on size and amount of wood elements across the tree trunk of Indian blackberry (Syzygium cumini Skeel.). Compared with the control, vessel elements in different positions along pith to cambium were significantly shorter (31-49%) and narrowe...

The main objectives of this study were to investigate the effect of different spacing levels on the biomass production and allocation in Conocarpus erectus trees grown in the arid environments of Saudi Arabia and to develop allometric equations for predicting the total above-ground biomass of these trees as well the biomass of each tree component (...

Seedlings of Zizyphus spina-christi trees grown from seeds were planted intensively in the field at the Experiments and Research Station of College of Agriculture, King Saud University near Riyadh City. After a year, the trees were subjected to thinning through three consecutive years and evaluated for growth and biomass production. Starting from t...

The growth and biomass production of six acacia species were studied in the field for 4 years. The species used were Acacia asak, A. negrii, A. seyal, A. karroo, A. ampliceps, and A. stenophylla. The first three species are indigenous while the others are exotic. The results showed both A. ampliceps and A. asak with 100% survival while all A. negri...

Oriented Strand Board (OSB) is non veneered composite panel that has been developed recently to perform as structural replacement for plywood in house construction. This dissertation investigate the use of aspen strands (populus termuloides) and paper birch strands (Betula papyrifera) in manufacturing laboratory scale OSB under different technologi...

A set of eight regression equations for predicting the total overground biomass of the tree and its components ( stem, branches and foliage) as well as stem volume were developed for three hardwood species namely Eucalyptus camaldulensis, Casuarina glauca and C. cunnginghemiana. The data of diameter at breast height (dbh), total height (H), and cyl...
