| Abstract: | Achievements in the research of mechanisms of the seed dormancy and methods improving Leymus chinensis seeds germination rate both at home and abroad were reviewed. The methods mainly comprised physical, chemical and hormone treatments,fluctuating temperature and low temperature methods were more effective, practical and deserving further researches. In addition, the main problems existed in this research area were discussed and some detailed suggestions for the future research direction were put forward. |
