Shoot elongation of Acer buergerianum Miq. was investigated for four yearsafter the planting of the two-year-old seedlings. The tree form of A. buergerianum is largely determined by the two types of shoot elongation. The first one is a normal monopodial branching of the tree with a decussate phylotaxis, and the second one is a monopodial branching with a hampered main axis. The second year elongations of primary branches of the two types are different with each other, but the elongation characterics on and after the third year are mostly same between the two, i. e. the longer branches have the longer elongation, and the characteristics don't change with the height of branch. These characteristics make the shrub-like tree form A. buergerianum.
