[目的]研究不同处理方式对葫芦苏铁种子发芽的影响, 提高葫芦苏铁种子繁育技术水平.[方法]通过去除种皮, 使用清水、0.1 mol/L盐酸、0.1 mol/L醋酸浸泡等处理方式对葫芦苏铁种子进行研究.[结果]葫芦苏铁种子在0.1 mol/L盐酸中浸泡12 h, 其发芽率最高, 达80.0％;在清水中浸泡, 种子发芽率和发芽势均较低, 分别约60.0％、40.0％.种子去皮起始萌发时间为8 d, 与不去皮时55 d相比明显变短;种子去皮后的发芽率和发芽势分别为80.0％、80.0％, 与不去皮时73.3％、50.0％相比, 均明显提高.[结论]该研究可为葫芦苏铁种子繁育提供参考依据.%[Objective]To study the effect of different treatments on the germination of Cycas changjiangensis, improve the seed breeding techniques. [Method]The seed germination of C.changjiangensis was studied by removing the seeds and soaking with clear water, 0.1 mol/L hydrochloric acid, 0.1 mol/L acetic acid.[Result]Germination rate was the highest when soaked the C. changjiangensis seeds in 0.1 mol/L hydrochloric acid for 12 hours, reaching 80.0％.When soaked them in clear water, the seed germination rate and potential were low, just about 60.0％ and 40.0％.Comparing with the initial germination time of the normal seeds which need 55 days, it became obviously shorter just need 8 days when it was peeled. The germination rate and germination potential of the peeled seeds were both 80.0％, which were significantly higher than the normal seeds.[Conclusiun]This study can provide reference for seed breeding of C.changjiangensis.
