| Abstract: |
| In this experiment, the tissue culture seedling of Cunninghamia lanceolate was used to build the
cutting orchard through the way of cutting orchard establishment and cutting propagation technology, which could
expended the propagation coefficient of high genetic quality tissue culture seedlings. Three circle samples were
randomly selected from the cutting orchard, and the diameter on ground high (DGH) and the quantity of coppice
shoot were measured to analysis the early growth of cutting orchard. The results showed that the performance of
DGH and the quantity of coppice shoot among each sample were similar in the early stage. The analysis of variance
(ANOVA) result indicated that there was no significant difference between the DGH and the quantity of coppice
shoot. It was confirmed that the tissue culture seedlings of C. lanceolate were from the same clone, and the genetic
differences were not significant with consistently performance. |
