Abstract

Effects of NaCl, Na2SO4, and MgSO4, and their combinations on germination and seedling development of bitter lentil were studied. Both of these processes were inhibited by the three salts used . Seedling development, however, was more sensitive to salt treatment than germination. The effect of MgSO4 on germination was essentially osmotic, while that of NaCl and Na2SO4, was presumably due to toxic or ionic actions. Both Na and Cl were more toxic than Mg and SO4. Magnesium sulfate combined with NaCl and with Na2SO4 did not only overcome the inhibitory effects of NaCl and Na2SO4 on germination and seedling growth, but there occurred also a remarkable synergism in both processes, as a result of such combinations.
