在不同温度、不同药剂处理条件下,对白花湖北木兰(Magnolia sprengeri Pamp)进行发芽试验。结果白花湖北木兰发芽的最适温度为20℃左右;其发芽势计算应以前8d发芽数为标准;其硬实种子采用40%NaOH处理1-2h发芽效果最好。
Under different temperature and different treatment conditions, the Magnolia sprengeri Pamp was germinated. Results The optimum temperature for sprouting of Magnolia sieboldii was about 20 ℃. The calculation of germination potential should be based on the number of sprouts of the previous 8 days. The best germination was obtained when the hard seeds were treated with 40% NaOH for 1-2 h.
