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.
