ترجمة الملخص

This research carried out during the years (2009-2010) at the research center of The Al-Furat University, where it planted seeds of four cultivarsof date palm (Barhi-Khstaoi–Majhoul-Zahidi) to determine the effect of the stress of drought and saline on the percentage of seed germination and the length of the Seedling and the number of leaves and on productivity net photosynthesis and the content of total chlorophyll and the number,weight and length of lateral roots. They found that the items studied varying in sensitivity to salinity, drought and was less damage for salinity is Khstaoi then Zahidi then Barhi then Majhoul, reaching the percentage of germination in the cultivar of Khstaoi(90-75-50) % at concentrations (8-12-16) g/l, respectively As for the drought was less affected is Barhi then Zahidi then Khstaoi then Majhoul, reaching the percentage of germination in the cultivar of Barhi (90-75-65%) at concentrations (12-18-24) g/l. The experience led to the conclusion: Increasing concentrations of salinity in irrigation water reduced the percentage 003of germination and the length of the seedling and the number of leaves and the content of chlorophyll and productivity net and the number and weight of lateral roots in all varieties except Khstaoi he found that the number, weight and length of lateral roots increased up to a limit of concentrations, and then began to fall. An increase of concentration of the drought in the irrigation water reduced the percentage of germination and the length of the seedlingand the number of leaves and the content of chlorophyll and productivity net and the number and weight and length of lateral roots in all varieties except Barhi he found that increasing concentrations of drought have led to the increase in the number, weight and length of lateral roots so we can deduce that:cultivar Barhi is tolerant to drought either cultivar Khstaoi is tolerant to salinity.
