ABSTRACT
The response of Zini grapevine to chloride salinity of six electrolyte concentrations of the irrigation water was investigated on two years old transplants grown hydroponically for nine months. Irrigation water salinity was increased at 20 molc m-3 increments to a maximum of 100 molc m-3 at constant stoichiometric ratios of 3:1 for Cl: SO4 and 1:1 for Ca: Mg and fixed sodium adsorption (SAR) of 5. The results revealed significant decrease in plant height, number of young shoots and leaves and dry weight of the plants. Negative salinity effects on vegetative growth of the plants were appeared at an electrolyte concentration of 60 molc m-3 and more. Increasing salinity levels increased proline contents and decreased chlorophyll concentration of the plants. Leaf Na and Cl contents were considerably increased and K and Ca contents decreased by increasing electrolyte concentration of irrigation water, whereas N, P and Mg were practically unaffected. Selectivity ratio for Na and K transport to the leaf was affected by salinity treatments. The exclusion ability for Na was markedly higher than that for Cl especially at higher electrolyte concentrations.
