AbstractThis study was carried out as partial study to search the mechanisms of salt tolerance in date palm tree. The result shows the salinity in irrigation water as NaCl( 0 ,6 ,12 ,18 , 24 )dS/m was significant effects on some chemical substances (proline , carbohydrates and chlorophyll) and some vegetative characteristics (leaf length and root length). The salt irrigation water was a significant increase in proline content in leaf and root with salt concentration increase, the proline concentration at 24 ds/m reach (25 ,18.8)µg/g dry weight in leaf and root respectively , whereas there were no significant changing in carbohydrates and chlorophyll with salt concentrations increase tell 12 dS/m, thereafter decrease in this characteristics with increase the salt concentration, the carbohydrates concentration at 24 ds/m reach (33.5 ,21.9)mg/g dry weight in leaf and root respectively and chlorophyll was reach (2.1)mg/100g fresh weight, this matter was correspond with vegetable characteristics.
