摘要:
为了促进美国白蜡树种在沿海防护林和风景林的推广和应用，对美国白蜡种子进行了不同休眠处理和育苗技术试验。结果表明:美国白蜡种子具有休眠的特性，种皮障碍、种皮和胚乳含有休眠抑制物质是美国白蜡休眠的主要因素；采用混雪堆藏的方法，有效的打破了美国白蜡种子的休眠；处理后的种子采用条播法进行播种，平均出苗率在90%以上。
Abstract:
In order to improve the promotion and application of Fraxinus americana in coastal shelter forest and ornamental forest,different treatments on seed germination and sowing of Fraxinus americana were studied,the results showed that the seed of Fraxinus americana had dormant characteristic,the main dormancy factors were impediment of seed capsule,inhibitory substance contained in seed capsule and endosperm; seed dormancy had been effective broken when stored in the snow,the average rate of seedling was above 90%when strip sowing .
