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1 d,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1 d,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 indicated 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 Cunninghamia lanceolata before sowing.
