| 摘 要： | 采用21种不同的方法对德昌杉种子进行对比处理,结果表明,用25℃温水浸种1h发芽率最高,为28.67％,其次为用40℃温水浸种1d,发芽率达27.67％,用100℃沸腾水处理5 min钟的发芽率最低,为12.33％,整体来看,用40℃温水浸种1d,发芽较快,出芽整齐,是德昌杉育苗前进行种子预处理的最佳方法.

| Abstract: | Twenty-one methods were used to treat the seeds of Cunninghamia lanceolata. The results indi- cated that the germination rate was the highest by the method of soaking seeds with 25℃ warm water for 1 hour,reaching 28.67%. The second high germination rate was 27.67% by soaking seeds with 40℃ warm water for 1 day. The lowest germination rate was 12. 33% by soaking seeds with 100℃ boiling water for 5 minutes. On the whole, the method of soaking seeds with 40 ℃ warm water for 1 day was the best, for the seeds germinated fastest, and sprouted tidily, which was the best way of seed pretreatment of Cunning- hamia lanceolata before sowing. |
