In order to study the effect of salinity stress and different concentrations of lead under the influence of stress ameliorator, a factorial experiment was carried out in a completely randomized design with three replications. The experiment consisted of salinity stress at three levels (0, 25 and 75 mM of sodium chloride), lead in three concentrations (0, 10-5, 10-3 M of Lead nitrate) and stress ameliorators included 0 and 5 mg/L sodium selenate and 200 μm sodium hydrogen sulfide. The results showed that salinity and lead caused a significant reduction in root and shoot dry weight, absorption of potassium and zinc in root and shoot. Different concentrations of Lead had different effects on the studied traits. At 10-5 M of lead nitrate was observed, the reduction in absorption of lead and as a result improvement in root and shoot dry weight than without salinity. Whereas, application of selenium and hydrogen sulfide significantly improved the growth traits of garlic under salinity stress and Lead. Application of 5 mg/L sodium selenate and 200 μm sodium hydrogen sulfide cause reduce in the accumulation Pb in garlic seedlings and this is followed by an improvement in the content of the elements and as a result, growth increased under salinity stress and lead concentration especially at 10-5 Pb However, in the concentration of lead 10-3M, this effect was not observed. It is worth noting that in the present experiment, the positive effect of selenium on sodium hydrogen sulfide was more pronounced.
