摘　　要：[ Objective] To explore the effects of different seed colors on seed germination and callus induction of Leymus chinensis. [ Method ] According to the color of mature seeds of Leymus chinensis, they were divided three color types, namely, pale yellow, yellow and black. Their seed germination and callus induction were observed. [ Result] The pale yellow Leymus chinensis seeds had higher germination rate （32.5%） and rate of callus induction （28.5%）. Based on the results of the TI＇C method and electrical conductivity, the seed viability was decreased with the deepening seed color. [ Conclusion] The study laid the foundation for establishing highly efficient plant regeneration system of Leymus chinensis.[ Objective] To explore the effects of different seed colors on seed germination and callus induction of Leymus chinensis.
