Abstract:
In order to define the salt-tolerance of the T.pretense L.in this experiment，the seed of the T.pretense L.was used as experimental material，with different concentration of NaCl solution，NaHCO3 solution，NaCl and NaHCO3 (1∶1) mixed solution in a petri dish to simulate three kinds of saline environment，and observe the germination condition of the T.pretense L..The results showed that with increasing concentration of NaCl and NaHCO3，germination rate，germination potential，the relative germination rate，germination index，vigor index，radicle length，and seeding fresh of T.pretense L.seeds were reduced.Seedling fresh weight and radicle length showed a significant negative correlation，the relative salt damage rate was positively related to the concentration of the solution.NaCl stress concentration of salt tolerance in seedling germination of T.pretense L. was 8.091‰，half inhibitory concentration was 10.146‰，limit concentration was 12.200‰.NaHCO3 stress concentration of salt tolerance in seed germination of T.pretense L.was 5.483‰，half inhibitory concentration was 7.434‰，limit concentration was 9.386‰.NaCl and NaHCO3 (1∶1) mixed solution concentration of the salt tolerance of T.pretense L. germination was 6.081 ‰，half inhibitory concentration was 7.253 ‰，limiting concentration was 8.425 ‰.Distilled water test showed that the three kinds of saline stress T.pretense L. seeds had different degrees of sprout.From the foregoing，T.pretense L. seed had a certain resistance to salt and alkali.
