%X The effects of different salts and water stresses on the seed germination of Chenopodium glaucum L. were studied. The results sh ow that th e seed germination percentage decreases significantly with salinity or os motic po tential increase when salt solution concentration is higher than 0 05 m ol/L or the osmotic potential of PEG solutions is lower than -0.2MPa.Germin ation of seed s treated by MgSO 4 is less affected and then the order is those by mixed salt, NaCl,Na 2CO 3, Na 2SO 4 and MgCl 2. In solutions with the osmotic potential of less tha n -0.5MPa,the seed germination percentage is lower in NaCl than that in is o osm otic PEG.After the non germinated seeds from all the treatments are transferred to distilled water, the finial germination percentage indicates that a certain d egrees of salt and water stress have no much effects on the seed germinati on pot ential ability.Basically the germination recovery percentage increases w ith an i ncrease of pre transfer salinity.The osmotic stress in wh ich seed germina tion ability is not hurtful varies with the kind of solutions.
