Abstract:

In this text, the Spuriopimpinella brachyara seeds were selected as the trial material, and through the experiments such as chemicals treatments, PGR treatments, stratification treatments and comprehensive test treatments in order to find out the method that could break the dormancy of seeds. The results showed that cold temperature stratification and stratifying outdoor under low temperature had broken the dormancy of seeds, the cold temperature stratification (4±1)℃ was the best treatment that had higher germination percentage than other stratification treatments. With the experiments of adopting different concentrations of GA3, IAA, 6-BA pretreatment combine stratification resulted: soaking the seeds in GA3 for 24 hours, and then stratifying seeds under low temperature (4±1)℃ for 100 days was the best technique to break the dormancy of seeds, and the germination percentage could achieve 60% ,which had high germination capacity and low rotten percentage, relieved the dormancy of the seeds of Spuriopimpinella brachyara on the whole.
