Abstract：In order to evaluate the effects of different saline-alkali types and levels on the germination characteristics of cucumber seeds,three varieties of cucumber seeds,Baisitiao,Lüruyi,and Pamanjia,were used as materials.Seed germina-tion related indicators were measured under different concentrations of Na2CO3,NaHCO3,and NaCl stress.Regression analysis and calculation of membership function values were used to determine the tolerance threshold of cucumber seed germination to salt-alkali stress.The results showed that all germination related indicators of cucumber seeds significantly decreased with the increase of salt-alkali concentration.The tolerance to Na2CO3 stress ranked as Lüruyi>Baisitiao>Pa-manjia.The tolerance to NaHCO3 stress ranked as Pamanjia>Lüruyi>Baisitiao.And the tolerance to NaCl stress ranked as Pamanjia>Baisitiao>Lüruyi.The inhibitory effects of the three types of saline-alkali stress on cucumber seed germination was NaCl<NaHCO3<Na2CO3.In conclusion,all the three varieties tested exhibited a certain degree of saline-alkali toler-ance and can be used as cultivated cultivars for cucumber production in facilities during of soil improvement processes.
