Considering the branch and leader bud of Gordonia acuminata as basic unit of modular populations,the dynamics of leader buds and bifurcation ratios were studied using data from different sampled trees with different age.The results show that the branching pattern was stationary on both within species and within tree,and was not constant on within main branch scale.The number of branches was not a constant geometric progression with the branching order number within a main branch,so the bifurcation...
