对‘通选7号’和‘川草3号’2个品种虉草种子采用物理和化学处理方法，测定各处理对种子萌发的影响，确定其休眠原因，找出快速、有效的破眠方法。结果表明，这些处理均能不同程度地促进2个品种种子的萌发。‘通选7号’种子经机械处理后发芽率最高，破皮种子的发芽率与具稃种子和去稃种子的发芽率有显著差异，具稃种子和去稃种子之间差异也显著，稃和种皮显著影响种子的萌发。因此，可以推论‘通选7号’种子的休眠原因是稃和种皮引起的综合性休眠，可通过去稃和磨破种皮的办法有效破除其休眠。‘川草3号’种子经剥去稃施加较高质量浓度GA3（赤霉素）处理后，发芽率达到最高，GA3的施加可能引起了种子内萌发促进物和抑制物新的动态平衡，刺激胚部形成水解酶类，从而引发种子，进而得出，‘川草3号’种子的休眠原因是胚部生理性障碍引起的综合性休眠，通过400 mg· L-1 GA3处理24 h可有效破除休眠。

By physical and chemical treatment on Ph alarisa rundinacea L.Tongxuan No.7 and P.arundinaec a L.Chuancao No.3, we determined the germination rate to ensure dormancymechanism and find out the rapid and effective breaking techniques .These treatments can increase the germination rate.The mechanical treatment is the best method in promoting the germination rate of P.arundinacea L.Tongxuan No.7, and grinded away seed coat has significant differences between intact seeds and naked seeds.P.arundinaec a L.Tongxuan No.7 dormancy is caused by seed coat andlemma , and can be overcome by grinding away the seed coat and removing the lemma.P.arundinacea L.Chuancao No.3 seed get the highest germination rate under higher content of GA3 .GA3 can cause new dynamic balance of accelerant and inhibitor, stimulate the embryo composed hydrolase, and trigger the seeds.Therefore, P.arundinacea L.Chuancao No.3 dormancy is caused by the embryonic physiological disorder , and can be successfully overcome by presoaking in 400 mg/L GA3 for 24 h.
