西洋参种子属于种胚后熟类型。只有完成种胚后熟,种子才能发芽出苗。一般从果实成熟到种子发芽需19个月时间。在此期间需完成种胚形态后熟和生理后熟两个阶段。新收获的种子种胚仅0.2—0.5毫米,后熟到2.1—2.8毫米时开始裂口。因此西洋参要妥善处理好种子,才能播种。1.隔年裂口种子处理.在测定种子质量后,先将其放入清洁容器中,用清水冲洗三、四遍。再根据种子裂口率高低和干湿程度酌情浸泡12—24小时,中间换水三、四次。如果种子不干燥,不必进行浸泡。浸泡时将秕籽和好籽分别捞出,通风阴干。再与清洁的河砂或风化砂(经过筛)按1份种子、3 American ginseng seeds belong to the type of embryo ripening. Only after the completion of embryo ripening, seed germination emergence. Generally mature from the fruit to the seed germination takes 19 months time. During this period to be completed embryo morphology and ripening after two stages. Freshly harvested seeds embryos embryo only 0.2-0.5 mm, after ripening to 2.1-2.8 mm began to breach. Therefore, American ginseng should properly handle the seeds in order to sow. 1. The next year cracked seed treatment in the determination of seed quality, the first into the cleaning container, rinse with water three or four times. According to the level of seed gap and wet and dry degree as appropriate, soak for 12-24 hours, the middle of water three or four times. If the seeds do not dry, do not have to soak. Soak the seeds and seeds when soaked, ventilated dried. Then with clean river sand or weathered sand (through the sieve) by 1 seed, 3
