Abstract

Effects of NaCl stress on seed germination and seedling growth in wheat were studied in this paper. The results showed that the germination rate of the seeds treated with NaCl concentration at <;100 mM, germination rate of the seeds was not significantly comparing with control, however the germination of those seeds treated with NaCl at higher concentration (≥200 mM) was inhibited and at 400 mM NaCl concentration no emergence of germination was noticed. The root length, shoot length and fresh weight of seedlings also decreased with an increase in NaCl concentration and treatment time. Activity of POD tended towards descenting after ascenting. MDA contents tended to go up steadily within lower concentration of NaCl, then sharply within higher concentration of NaCl.
