| Abstract: | The study was conducted on sowing,cutting,grafting seedling technique and growth characteristics of Catalpa fargesii,the results showed that： seedling emergence rate was 21.82%,cutting seedling survival rate was 42.3% survival rate of grafting was 74.0%.Quality indexes of seedling growth were analyzed.The sequence of different length cutting seedlings quality evaluation value was as follows： 12 cm cuttings（21.6） 8 cm cuttings（20.6） 16 cm（19.8）.The growth and morphological characteristics of direct seedling and cuttings seedling had good performance in seedling stage.The results will provide theoretical support for seedling technique of Catalpa fargesii. |
