Abstract:
The analysis and comparision of the growth charactristics of 13 tree species of Magnoliaceae were carried out by using qualitative and quatitative analysis. The results showed the followings:
1. The ordination of fast-growing tree species by principal component analysis indicated that their mean increment is higher than that of Magnolia grandiflora used as control in the experiment. The fast-growing species showed two growth peaks during seasonal growth, and the fast-growing point is most likely to appears from middle of June or July.
2. The seasonal growth can be expressed by a Logistic model. By parameterization of the model with the experiment data, some information such as fast-growing point, fast-growing period and value of growth characteristics in each tree species can be obtained.
3. There is a significant linear corelation between tree growth increment and the product of growth time and maxium speed of growth.
