Excessive salt in salt-affected soil affects the growth and development of crops.Although soil salinity affects the growth and development of crops at all the growth stages,the salt-sensitiveness of some crops differ remarkably at various stages.To lerance to salinity is not a fixed property of a species but varies with the growth stages of the crop.A pot culture experiment was conducted to determine salt tolerance of barley and wheat at various growth stages.The soils tested were salinized at various stages with distilled water containing salt at four levels.After salinized,the osmotic potential of soil solution increased by 0,-0.4,-0.8 and -1.6MPa,respectively.
