Abstract
Two pots experiments had done at Faculty of Agriculture's Nursery in MansouraUniversity , Mansoura city , Egypt . In two summer seasons (2011 and 2012) to study the effect of Sodium chloride salinity levels on (vegetative growth) and (chemical contents) of Jojoba ( Simmondsia chinensis ) seedlings . Five treatments were arranged in complete block randomize with five salinity levels the control ( Tap water ) , 2000 , 5000 , 7000 and 10000 PPM . The most important finding could be summarized as follows: - The increasing of the salinity from 2000 to 10000 PPM decreased all plant vegetative growth characters and the total chlorophyll content compared to control . - A marked increasing in the ion leakage , the protein carbonyl group and the lipid peroxidation number in both seasons with the salinity increasing from 2000 to 10000 PPM compared to control .
