Abstract
The dormancy and methods of breaking dormancy of barnyard grass seeds were studied.The results of seed dormancy under different environmental conditions showed that the seeds of barnyard grass would get into dormancy after maturity,and the dormant stage was different under different environmental conditions.The dormancy of barnyard grass seeds collected in July 2004 could be broken by buried in soil for five months,and they got into the non-dormant state for the next six months.The dormancy could also be broken by stored for one year under the room temperature.However,the seeds stored in refrigerator for one year were still dormancy.The seeds immersed in GA3 with 1 000.0 mg/L concentration for 240 h or H2SO4 about 10-20 min could relieve the dormancy of barnyard grass seeds,but other disposal of GA3 and H2SO4 could not break dormancy of barnyard grass seeds.
