Abstract:: The effects of various concentration of seawater on T.repens seed germination and seedling growth were studied in this paper.The results showed that the germination rate，germination percentage，germination index，vigor index and main root length of T.repens seed were decreased with increasing concentration of seawater.The significant differences of the seed vigor index and main root length were observed between the lower concentration(1%)seawater treatment and CK，so the seed of T.repens was very sensitive to seawater stress.While，there was not significant difference in the germination rate，germination percentage and germination index of T.repens seed between the lower concentration(1%) seawater treatment and CK，and seedling growth and development of T.repens treated with high seawater concerntration were similar to that of CK.It was possible to screening of varieties of T.repens resistant to salt and alkati.
