芳樟穗条性状对扦插成活率的影响

The Effect of the Characteristics of Cinnamomum camphora var. linaloolifera Cuttings on Their Survival Rate

利用温室大棚进行芳樟容器扦插育苗试验。结果表明,芳樟穗条性状对扦插成活率的影响显著或极显著,同一枝条梢部穗条的扦插成活率显著高于中部、下部和基部;穗条长度10 cm、直径0.3 cm、带2片半叶、下切口切为斜面的穗条,扦插成活率高于其他处理。最佳穗条应是同一枝条靠梢部1～2段,长度10 cm左右、直径0.3 cm、带2片半叶、下切口成斜面的穗条。

Cinnamomum camphora var. linaloolifera is an elite variety of oil use forest selected from C. camphora germ plasm resources, and it can maintain excellent economic traits only to adopt vegetative propagation. Using Greenhouse for containerized cutting seedling experiment, the results show that the character of C. camphora var. linaloolifera affect on the cutting survival rate was significant or extremely significant. The survival rate of the top significantly higher than the middle, the lower and the base in the same branch; the strip than 10 cm long, 0.3 cm diameter, with two and a half leaf, a slope cut shape, cutting survival rate higher than other treatment. The optimal combination is the closed shoot tip 1-2 section in the same shoot, 10 cm long, diameter of about 0.3 cm, with two and a half leaf, the shape of below cut is slope.
