Abstract: In order to fully understand the dormancy mechanism and germination process, to solve the breeding problems of Carex brunnescens seeds. The seed germination experiment of Carex brunnescens was carried out. After the seeds were dealt with physical methods (soaked with hot water, scarification, stratification), chemical methods (seed soaking by H2SO4, NaOH, GA3) and integrated methods. The results showed that Carex brunnescens had dormancy characteristic and not germination in natural condition. 10% NaOH and scarification+GA3 1000 mg/L take some effect in breaking dormancy and promoting germination. The germination percentage was 13.75% and 12.5%, respectively.
