The effects of irrigation water or soil salinity on physiological aspects of pea (Pisum sativum cv. Meteor) plants were contrived. Ten weeks old pea plants were treated with NaCl at 0, 40, 90 and 140 mM in nutrient solution. Plants were grown in controlled environment and harvested at each 3 days interval for decisiveness of physiological parameters. Photosynthetic rate, relative water content, stomatal conductance and chlorophyll contents reduced by increasing the NaCl concentration, while CO2 concentration and free praline content intensified. By experiment it was adumbrated that high salinity level along with prolonged accentuate duration is more drastic to pea plants physiology. Results also exhibited that pea plants could indulge 40 and 90 mM NaCl but are sensitive to 140 mM.
