摘要
为了解温水浸种对旱冬瓜种子发芽的影响,采用初始温度为50℃的温水分别0、3、6、12、24和48 h的不同时间浸泡冷藏（约4℃温度）1 a的旱冬瓜种子。结果种子平均发芽率、发芽势和发芽时间分别为35.0%-44.8%、19.3%-24.5%和11.3-12.7 d;虽然温水浸泡种子略微提高了发芽率,但处理间此3个指标无显著差异（P=0.122-0.271〈0.05）。通过冷藏可延长种子贮藏时间,实现播种时间的调整。
In order to detect effects of warm water presoaking for Alnus nepalensis seeds on germination traits,one year refrigerating A. nepalensis seeds（about 4℃） are presoaked by warm-water of starting temperature 50℃ for 0,3,6,12,24 and 48 h respectively. The results show that average germination rate,germination energy and period are 35. 0% - 44. 8%,19. 3% - 24. 5% and 11. 3 - 12. 7d respectively. Although warm-water presoaking has appreciably increased germination rate,there are no significant differences among three index under treatments（P = 0. 122 - 0. 271 0. 05）. Refrigerating method could prolong the storage period of A. nepalensis seed,which may adjust sowing-seed time.
