SUMMARY Introduction – Date palm (Phoenix dactylifera L.) is a perennial plant, the pillar of oasis’s ecosystem and a target to pests attack. Distribution and the incidence of date palm pests varied differently in each country, between regions and among the date palm plantations. Materials and methods – During 2017, a study was undertaken using 4,3...

The quantification of water flow through the stem is vital for date palm (Phoenix dac-tylifera L.) to promote a good water stress management. The thermal dissipation probe (TDP) method developed by Granier is widely used to evaluate transpiration of forest trees; however, there are contradictory reports regarding its reliability. Considerable error...

Dates represent a very important energy source that contains a wide range of functional, nutritional, bioactive, and aromatic components. Dates characteristics have been widely studied but none has been conducted on the pre-harvest factors responsible for the quality variation. The aim of this study is to evaluate the effect of pre-harvest practice...

Abstract: Palm trees are a family (Arecaceas) of plants with hundreds of species. Most economically important species are date palm (Phoenix dactylifera.L), coconut palm (Cocos nucifera), and oil palm (Elaeis guineensis).Being monocotyledons, palm trees show distinct differences of the wood structure compared to common wood species. This study aime...
