| 摘 要： | 以秦艽为试验材料,研究了不同贮藏方式和不同浓度赤霉素处理对其种子萌发的影响,同时观察了种子至种苗发育过程。结果表明,在25±1℃的温度条件下,200mg/L的赤霉素处理对秦艽种子的发芽势和发芽率均有显著的促进作用。自然条件下贮存1年后的种子萌发率显著下降,种子为短命型,零下低温保存可以延长种子寿命。种苗发育初期有根环和下胚轴毛出现,当年生苗呈莲座状叶丛。

| Abstract: | This paper studies the effects of the different store ways and the gibberellins of varying concentration on the seed germination,and observed the seeding development of Gentiana macrophylla.Our results show the promoting effect is significant to the germination energy and germination rate of the seeding by 200mg/L gibberellin at the 22±1℃ temperature.Because the seeds are ephemeral,The seed germination rate decreased significantly at the natural conditions of storage after 1 year.The way at subzero cryopreservation may increase the seed longevity although the seed longevity of Gentiana macrophylla is one year.The root collar and hypocotyl hairs appear on the early developing of the seeding.The leaves of the one-year seedling arrange rosulate. |
