In order to improve the germination rate of Q.virginiana seeds,the seeds of Q.virginiana were soaked in different concentrations of exogenous hormones indoleacetic acid(IAA)and naphthoacetic acid(NAA)for 1 h and 3 h,respectively.The seeds were soaked in water for 1 h and 3 h,and the germination indexes of the seeds were observed at a constant temperature of 20℃.The results showed that the germi-nation rate of seeds soaked with 100 mg/L naphthoacetic acid(NAA)for 1 h was 66.70%.The germination rate of indoleacetic acid(IAA)was 53.30%at 100 mg/L,200 mg/L for 3 h and 150 mg/L for 1 h.The germination index of seeds soaked with 100 mg/L indoleacetic acid(IAA)for 3 h was 16.38.The radicle growth of seeds soaked with 100 mg/L indoleacetic acid(IAA)for 3 h was 3.80 cm,which was better than the control and other treatments.
