Abstract

Salinity has different effects on crops and limits their productivity. Halophytes tolerate high salt conditions. .Aeluropus lagopoides is a stoloniferous, prennial halophytic grass from poacea family. Although it usually grows in high salinity conditions but its growth is normally without any symptoms of SALT STRESS. In this study, seeds were cultured on mesh in hydroponic medium supplemented by ½MS medium. After 21d, seedling were treated by NACL (600 mM), ABA (50 µM), Ca2SO4 (5mM), (NaCl+Ca2SO4), (NaCl+ABA) and (Ca2SO4 +ABA) and then several biochemical compounds were measured in shoots and roots of Aeluropus lagopide. Results showed that ABA treatment reduced pigments content lower than other treatments. In addition, ABA decreased K+/Na+ rate and MDA content in the roots and caused accumulation of proline. Although Ca2+ elevated K+/Na+ rate in the shoots and decreased it in the roots, but the effects of Ca2+ on the changes of the proline and MDA content in shoots were in contrast to them in roots. Under SALT STRESS, K+/Na+ rate decreased in shoots and roots and increased proline content only in shoots. It seems that ABA has not significant effects on ionic adjustment and MDA content of shoots. On the other hand, Ca2+ reduced shoot stress in A.Lagopoides by increasing K+/Na+ rate. Also, results indicated that the species has the advantage of accumulation of proline in shoot and Na in root for osmotic adjustment during salinity stress as this caused a decrease in MDA content both in shoots and roots.
