摘　　要：针对鸡树条荚蒾种子的深度休眠进行了不同阶段的试验,在层积催芽处理试验中,方法 6高温50天后转入低温这种处理(方法 6)的发芽势最高,为67%;而高温50天后转入中温这种处理(方法 3)的发芽率最高,为76%;在针对打破胚轴休眠的催芽后处理试验中,赤霉素100×10^(-6) mg/mL浸泡24 h的处理的出苗率最高,为84%,可以实现其种子的当年出苗。In this paper, according to the depth of the Viburnum opulus var. calvescens seed dormancy were studied in different stages, to explore the suitable tree seedling cultivation method. In stratification treatment, 6 after 50 days of low temperature high temperature method into this treatment the maximum germination potential was 67%, 3 and 50 days after the transfer to the high temperature method in temperature the processing method of the highest germination rate was 76%, the germination rate of the angle from the guarantee method should be adopted in 6; to break dormancy of hypocotyl germination test postprocessing in the process of gibberellin 100 ppm soaking for 24 hours, the highest germination rate was 84%, the year can achieve its seed germination.
