中文摘要：

在15，20，25，30，18／25℃下对新鲜的大同山秋海棠（Begonia daweishanensis S．H．Huang＆Y．M．Shui），紫叶秋海棠（B．purpureofolia S．H．Huang＆Y．M．Shui）和假厚叶秋海棠（B．pseudodryadis C．Y．Wu）进行萌发试验，发现大围山秋海棠及假厚叶秋海棠的种子在所有温度条件下均有较高的萌发率；而紫叶秋海棠的种子在30℃下萌发率较低。将3种秋海棠种子分别在室温，4℃及-20℃下贮藏60，90，180d，在18／25℃下进行萌发试验，发现在室温及4℃下，3种秋海棠的种子萌发率随贮藏时间的增加没有明显变化，而在-20℃下，随着贮藏时问的延长，3种秋海棠种子的萌发率均显著降低。

英文摘要：

We tested the germination of freshly matured seeds of Begonia daweishanensis S. H. Huang ＆ Y. M. Shui, B. purpureofolia and B. pseuclodryadis C. Y. Wu under 15, 20, 25, 30 ℃ and 18/ 25 ℃. Seeds of B. daweishanensis and B. pseudodryadis showed higher germination rate under all temperature regions, while the germination rate of B. purpureofolia was lower under 30 ℃. We also examined the germination after 60, 90 and 180 days of dry storage under ambient temperature, 4 ℃ and - 20 ℃ respectively. The result showed that have no effect on germination for all three when the duration of storage was prolonged under ambient temperature and 4 ℃, duration of storage species, but under - 20 ℃ , germination was depressed when the duration of storage was prolonged.
