Abstract:

Taking the seeds of Chloris virgate as test material，the effect of different concentrations of NaCl salinity 0，50，100，150，200，250 mmol/L on the germination rate，germination index and growth status of radicle and germ were determined；after removing the stress，the response of the seed and seedling were also observed.The results showed the germination rate and speed of Chloris virgate seeds decreased with stress of NaCl increasing，and there was significant negative correlation between germination rate and salinity.With salinity increasing，the radicle and germ lengths decreased and the inhibition on the radicle was more greatly than that on the germ.Recovery experiment revealed that Chloris virgate seeds could keep viable in salt solution.After removing stress，the seeds also germinate rapidly.After being tempered by the salt，the ability of growing of the seedlings was improved.
