| 摘 要： | 通过高枝压接继代培养和扦插苗继代培养等方式对思茅松（Pinus kesiya var.langbianensis）进行了无性繁殖试验，结果表明：对不同母树年龄的思茅松枝条进行高枝压接均能生根，而且生根后定植亦能成活生长，经断顶获得的穗条扦插亦获得了成功。此外扦插苗继代培养成活率较实生苗继代培养扦插成活率低，二者扦插成活率分别为54．2％和80．6％。

| Abstract: | An experiment on asexual propagation of Pinus kesiya vat. langbianensis was carried out by the way of subculture of high branch layering and cutting seedlings. The results showed that the branches on the seed trees of Pinus kesiya vat. langbianensis with different ages were used by high branch layering experiment, all of which could induce roots, and all branches cut after rooting could al- so survive and grow. It was successful to cut the scions acquired by broking tops. In addition, com- pared with seedling subculture, the survival rate of cutting seedlings subcultured was lower, which was 54.2 % and 80.6 % respectively. |
