| Abstract | ||
| A comparative physiological study was conducted on the salt tolerance of two plants from Leguminosae family were kidney bean (Phaseolus vulgaris L.) and cow pea (Vigna sinensis L.) , the study was including the effect of different concentrations (50 , 100 , 150 , 200) mMol / l of sodium chloride (NaCl) salt solution in addition of distill water as a control treatment , in the germination of seeds and concentrations of total sugar , reduced sugar , sucrose and starch , also the study included some chemical and physical properties of the used soil in the agriculture were the moisture of field capacity , the percentage of saturated humidity , soil texture , the value of ( pH ) and ( EC ) and the concentrations of some mineral ions (Na+ , K+ , Ca++ , Mg++ , Cl- , HCO3 - , CaCo3= , SO4= , CO3 = , PO4≡ ) , organic carbon and organic matter . The results were showed that , the increases of salinity concentrations causes a decrease in the percentages of seed germination of the both plants , the high percentages of germination were noticed at a control , whereas the low percentages at the salinity treatment (200) mMol / l of the plants seed , also causes an increase on the concentrations of total sugar , reduced sugar and sucrose and the high concentrations of them at the salinity treatment (200) mMol / l , whereas the low at the control , also the increase of salinity causes a decrease on the concentrations of starch , the low concentrations were noticed at salinity treatment (200) mMol / l , whereas the high concentrations at the control treatment . | ||
