摘    要:[目的]确保甘草种子萌发的数量和质量,为甘草育苗和大田播种提供技术依据。[方法]试验采用三因素随机区组设计,探讨了种子颜色、粒级和浓硫酸处理时间3个因素对甘草种子发芽、出苗的影响。[结果]试验得出,甘草种皮颜色、种子粒径大小和浓硫酸浸种时间都对发芽、出苗有显著影响。绿色、大粒、浸种时间在50~90min发芽率较高,其中浸种时间70min为最好。[结论]随甘草种皮颜色加深、粒径减小,出苗率有下降的趋势;随浸种时间的延长,出苗率呈先增加后下降的趋势。

关 键 词:甘草种子处理  发芽率  出苗率

Abstract:[Objective] The technical basis for licorice seedling-raising and planting in field was provided through the experiment in the quantity and quality of licorice seed germination.[Method] The effect of three factors such as the color,classification of seed,and the processing time of sulfuric acid on licorice seed germination were researched with the randomized block design.[Results] The result indicated that the three factors significantly affected its seed germination and emergence ratio.The seed with green coat color,large size,and soaked for 50-90 min showed a higher germination rate,especially for 70 min soaking treatment.[Conclusion] There was a downward trend of licorice seed germination rate with the deepening of seed coat color and the reduction of seed size;and its seed germination rate was increased firstly and then reduced.
Keywords:Licorice seed treatment  Germination rate  Emergence
