摘　　要：Salinity treatments （NaCl and Na2SO4） reduced plant growth and increased the accumulation of Na^＋, P^3＋,Fe^3＋ , Mn^2＋, and CIin root, stem, leaf and legume. The uptake of K^＋ reduced in the presence of both salts whereas uptake of Ca^2＋ retarded mainly by Na2SO4. Chlorophyll content was affected mainly by NaCl, while Na2SO4 treatment lowered the rate of photosynthetic activity. Both salt compounds caused accumulation of free amino acids including free proline but reduced the protein content in the leaves. The salt tolerance capacity of the broad beans plant in which the observations of the effect of salinity determined by different concentrations of NaCI and Na2SO4 on growth, chloroplast pigments, photosynthetic, free amino acids, free proline, protein and inorganic elements on plants are combined with observations on growth and yield, in order to arrive at a better understanding of their salt tolerance, has been studied and discussed in this paper. The results for the latter only （fruiting stage） are presented.
