Abstract
Poplar grows fast and can be used as row material in industry, pulp for paper, lumber and building products and as buffer strips to conserve plantation. Salinity has a major impact on plant growth and productivity. As tolerance of various poplar species to salinity is variable and imprecise, an experiment was conducted to evaluation different levels of sensitivity to salinity which consisting of factorial combination of 4 clones and 5 treatment {0.0 (control) 0.32%, 0.64%, 0.96% and 1.28%} of NaCl and CaCl2 with tree replications in a greenhouse in Shehid Fozveh Research Station of Esfahan Province from 1377 to 1379. Poplar clones include Populus nigra 63/135, P.deltoides 79/51, P. alba 44/9 and P. euramericana var. triplo. Salinity treatments were imposed by adding NaCl and CaCl2 (2:1molar ratio) to half  concentration Hogland Nutrition solution that ranged from 0 to 1.28% m/v percent .Result of this experiment showed that number of leaf, dry weight of leaves, stems and roots were decreased with increasing salinity. With increasing salinity, amount of Na+, Ca²+, Cl- and K+ were increased. P.euramericana var. triplo and P.deltoides 79/51 growth had most reduction rate. P.alba 44/9 showed higher tolerance compare to the others.
