Architectural Responses of Casuarina equisetifolia L Seedlings to Different Population Density
The branch characteristics of one-year old Casuarina equisetifolia L seedlings were surveyed and analyzed by the Strahler method in Dahe State-owned Forestry Centre, Changle County, Fujian Province. The results showed that C. equisetifolia with the density of 5-10 numbers per square meter had the highest ratio of branch diameter, whose crown showed a trend to uplift and expand with a better comprehensive living condition than the density of5 and 10-20 numbers per square meter. Therefore, the upper part of C. equisetifolia showed a trend to uplift and the lower part to expand, as the middle part between the above tow parts. It suggested that the adaption of branch characteristics of C. equisetifolia L is to make full use of environment and resource.
