摘　　要：以大叶芹(Spuriopimpinella brachyara)种子为材料,通过采用化学药剂、植物生长调节剂、层积处理及综合试验处理,寻找打破大叶芹种子休眠的方法。研究结果表明:低温层积处理和越冬层积具有破除大叶芹种子休眠的作用,低温层积(4±1)℃的条件较其他层积条件下种子发芽率高,是最佳的层积处理方法。采用不同浓度的赤霉素(GA3)、生长素(IAA)、6-苄基腺嘌呤(6-BA)预处理后结合低温层积处理,结果表明:250mg/LGA3浸种24h后低温层积100天可使种子发芽率达60%左右,发芽势较高,且腐烂率低,基本上解除了大叶芹种子休眠现象。In this text,theSpuriopimpinella 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 ofSpuriopimpinella brachyara on the whole.
