Abstract: In order to select suitable methods for salt tolerance identification of tulip,9 tulip varieties were identified by cultivation method and leaf disc method respectively.The results showed that the salt solution was Hoagland+0.6 mol/L NaCl by cultivation method,and the identification time was 18 days.The salt solution was MS+0.6 mol/L NaCl by leaf disc method,and the identification time was 4 days.Under the treatment of the two methods,the varieties with strong salt tolerance of tulips were both AD Rem and Ha Kuhn,while the varieties with weak salt tolerance were Word Favourite and Judith.The order of relative salt tolerance of 9 tulip varieties is basically the same by the two methods,among which cultivation method takes long time,high cost and requires a lot of manpower and material resources.Leaf disc method has the characteristics of short identification time,simple operation and low cost, and can be applied to the determination of large quantities of samples.
