Salinity can have damaging effect on plant growth either because of toxicity of specific ions or as a result of osmotic stress. Concentration of a salt has a significant role in this. Influence of two salts (NaCl and KCl) on germination and early growth of mungbean is being reported in this communication. Germination of Vigna radiata cv Hum-1 was reduced by higher concentration (100mM) of salts particularly sodium chloride. Radical length increased in treatments having lower concentrations (10mM) of sodium and potassium chloride, however, higher concentrations reduced radical length as well. All NaCl treatments and higher concentrations of potassium decreased plumule growth however plumule growth increased in 10mMKCl. Fresh and dry weight of different organs also exhibited more or less similar trends. Nitrate reductase activity reduced in sodium chloride treatments, however seedlings raised with potassium chloride treatments showed enhanced nitrate reductase activity.
