| 摘 要： | 通过不同无性系、不同家系、不同类型插穗,进行楸树嫩枝扦插繁殖试验,考察影响楸树生根的主要因子。结果表明:不同无性系、不同家系、不同类型插穗间扦插生根率存在较大的差异,且无性系扦插成活明显高于家系。扦插生根后,无性系80%为偏根,家系21%为偏根。

| Abstract: | Through the cutting propagation trials of different clones,different families and different types of cuttings of Catalpa bungei,the main factors were analyzed,affecting the rootage of Catalpa bungei cutting propagation.The result showed that there was significant difference between different clones,different families and different types of cuttings and the survival rate of different clones was higher than that of different families.After taking root of cuttings of Catalpa bungei,the lateral root was 80% of clones and 21% of families. |
