| 摘 要： | 以11个水稻品种为试验材料，设置3个浸种时间，研究浸种时间对水稻种子发芽势和发芽率的影响。结果表明：不同水稻品种的发芽势和发芽率存在显著差异，浸种时间对发芽势的影响不明显，但对发芽率有显著影响；浸种时间过短或过长均不利于种子发芽，本试验中浸种5d发芽效果最好。 |

| Abstract: | Eleven rice cultivars and three different seed soaking time (24h, 120h and 168h) were used to investigate the effect of different seed soaking time on germinative energy and germinative percentage of rice seed. The results showed that there were significant difference in germinative energy and germinative percentage of different rice cultivars, seed soaking time had no significant effect on germinative energy but had significant effect on germinative percentage of rice seed, and it was disadvantaged to seed germinate that seed soaking time was too short or long. Seed soaking for 5d was advantage for germinates in this study. |
