| Abstract: | The changes of ion contents betaine levels and betaine-aldehyde dehydroge-nase(BADH)activity in seedlings of halophytes-seepweed(Suaeda salsa)and nonhalo-phytes-barley(Hordeum vulgare)under different NaCl were comparatively studied. The re-sults of experiments suggested that the contents of K in seepweed and barley grown in NaClfor 96h decreased with increasing external salinity compared with controls, while the Na lev-els increased substantially and Na contents of seepweed were higher than barley. The betainelevels and the BADH activity of seepweed and barley shoots arosed with increasing externalNaCl concentrations and the amounts of these in seepweed were higher than barley. |
