Abstract:
The wild Oenothera biennis seeds in Changbai Mountain were used as test materials.The salt tolerance of Oenothera biennis L.at the seed germination stage and the growth stage of germ and radicle was studied,by using double-layer filter paper method and curve regression analysis,in order to provide reference for improving the survival rate of introduction and cultivation of Oenothera biennis L.〖JP〗under saline-alkali environment.The results showed that the germination rate,germination potential,germination index,vigor index and germ length were significantly lower than those of the control under different concentrations of NaCl,Na2SO4,NaHCO3 and Na2CO3,while the radicle growth was completely inhibited under different Na2CO3 concentrations.The salt tolerance half lethal concentrations of Oenothera biennis L.to NaCl,Na2SO4,NaHCO3 and Na2CO3 were 66.92,20.18,69.93,40.06 mmol·L-1 and 63.41,28.21,28.65,10.79 mmol·L-1 during the seed germination and germ growth stage,respectively.While the salt tolerance half lethal concentrations of Oenothera biennis L.to NaCl,Na2SO4 and NaHCO3 at radicle growth stage were 55.29,21.21,16.76 mmol·L-1,respectively.
