铃兰种子在2～5℃下经500ppm GA_3、0.2%KNO_3及水处理3个月后,转20℃发芽,23天后,前两项处理的种子,长出了胚根及芽,又以赤霉素处理苗长势最好,对照种子仅长出胚根,2个月后才长出胚芽。将马蔺种子的部分胚乳切除后,90%以上均可萌发。在25℃下添加250ppmGA_3,可使点地梅、落新妇及早开堇菜的种子破除休眠。角蒿种子在1～3℃中湿润处理1周,发芽率为84%。刚收获的紫花地丁及早开堇菜种子没有休眠现象,贮藏后逐渐进入休眠状态,加入500ppmGA_3溶液,并在1～3℃中20天,发芽率分别为81%及93%。阴地堇菜种子收获后立即进入休眠状态,添加500ppmGA_3溶液在1～3℃下20天,发芽率为60%。
The seeds of lily-of-the-valley were germinated at 20 ℃ after treated with 500ppm GA_3, 0.2% KNO_3 and water at 2 ~ 5 ℃ for 3 months. After 23 days, the seeds of the first two treatments grew the radicle and shoots, Treated with mithramycin was the best, and the control seeds only grew radicle, and germ was not seen after 2 months. Part of Iris seeds will be excised endosperm, 90% can germination. Add 250ppmGA_3 at 25 ℃, can relieve the dormancy of the seeds of Plum, the Bride and the Early Viola. Artemisia annua seeds were wet treated at 1 ~ 3 ℃ for 1 week, the germination rate was 84%. Freshly harvested Viola yedoensis and seeds of early genus Viola did not dormancy. After storage, the seeds were gradually put into dormancy. 500ppmGA_3 solution was added and the germination rate was 81% and 93% respectively at 1 ~ 3 ℃ for 20 days. The overwintered Viola seeds were put into dormancy immediately after harvesting. After adding 500ppmGA_3 solution for 20 days at 1 ~ 3 ℃, the germination rate was 60%.
