The effects of various salinities and desalination on seed ger- mination of six annual glycophytes (Artemisia sieversiana, J. Scoparia, Chloris virgata, Eragrostis pilosa, Chenopodium acuminatum and Chenopodium glaucum) were studied in Horqin Sandy Land, Inner Mon- golia, China. NaCl solutions of five concentrations (0 mM, as the control, and 50, 100, 200 and 300 mM) were used for saline stress and desalina- tion treatments. Increasing salinity significantly reduced germination percentages of A. Sieversiana, A. Scoparia, Ch.virgata and Ch. Acumi- nature, but had no effect on the germination percentages of E. Pilosa. Lower salinity levels (50 mM) significantly increased germination per- centage of Ch. Glaucum. High salinity might be a precondition for germi- nation after desalination for five of the six species, excepting E. Pilosa at NaCl concentration of 300 mM in comparison with non-primed seeds. Higher salinity (>200 mM) led to some specific ion toxicity and reduced seed viability of A. Sieversiana. No specific ion toxicity but an osmotic effect limited the germination of other five species was observed The final germination percentages (salinity stress and desalination) of the six species showed three variations in comparison with the controls, namely, indiscrimination, stimulation, and reduction. Germination responses to salinity and desalination suggested that the six species were separated into three categories. Three species (A. Sieversiana, Ch. Virgata and Ch. Acuminatum) showed similar germination responses to salinity with those of halophyte, but also showed a lower tolerance limit than most halo- phytes, although this was not always the case. A. Scoparia and Ch. Glau- cure exhibited some salt stimulation in seed germination percentages after desalination, whereas E. Pilosa did not show any obvious response to salinity. Therefore, salinity usually induces dormancy of seeds with strong germination capacity in fresh water, but has few, or even positive, effects on seeds with strong innate dormancy.
