不同外源激素处理对弗吉尼亚栎种子发芽的影响
Effects of Different Hormone Treatments on Seed Germination of Quercus virginiana in North America
摘要
Abstract
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.关键词
