Abstract Using water shield(Brasenia schreberi J.F.Gmel)newly collected seed as material,
the paper studied on the effects of different treatments on the germination rate and energy.The results
showed that 4 °C low temperature treatment had better effect on improving the germination rate of water
shield seed.It could get better effect to break dormancy of water shield seeds with the treatment of 4 °C
cold water storage,soaking with 500 mg·L-1 GA3 for 6 h and then in 40 °C water for 50 min.25 °C was
the best germination temperature.Under the condition of 20 °C, the seed would take long germination
cycle,and under the condition of 30 °C,the seed was easy to breed white rot around germination hole.
Under partial lighting conditions,seed had a higher germination rate,and almost no germination under
dark condition.
