Abstract: 

Medicinal plants are important in various industries. With increasing of saline lands and the shortage of agricultural lands, the improvements of salt tolerant plants are important. Cultivation of plants in hydroponic environment is a reliable and economical method in order to select the salt tolerant plant. An experiment was carried out in order to study the effect of different salinity levels on Plantago psyllium and Plantago ovata in seedling and whole plant stages in a complete randomized design with four replications in seedling stage and three in whole plant stages. The salinity levels applied were zero (control), 50, 100, 150, 200 and 250 mM. The result showed, by increasing salinity level percentage of germination, root length, shoot length, root dry weight, shoot dry weight and shoot/root ratio decreased. This decrease was different among these studied plants and there were significant differences between salinity concentrations. In the seedling stage, P.ovata showed more tolerant than P. psyllium. In the whole plant stage, with increasing salinity the most of characters were decreased but P. psyllium showed more tolerant than P. ovata.
