Abstract
The architectural development ofViburnum dilatatum andV. wrightii was investigated quantitatively. In both species, the major axis is developed from terminal buds of vegetative shoots and from axillary buds on the most distal nodes of reproductive shoots. The architecture of the two species is formed mainly by four branching patterns: a monopodial pattern (M), a sympodial pattern producing a pair of opposite daughter shoots (SP), a sympodial pattern producing a single daughter shoot (SS), and a pattern terminated with a dormant or dead bud (D). In the process of the architecture formation, four successive stages are recognized: 1) height growth, where the M pattern is dominant; 2) crown formation, in addition to the M pattern, the SP pattern occurs frequently; 3) crown expansion, the M and SP patterns are also frequent; 4) over mature, the M pattern becomes dominant again. These four stages are common to the two species, butViburnum wrightii proceeds with the crown formation stage more rapidly and stays in the crown expansion stage for a longer time thanV. dilatatum. The crown ofViburnum wrightii is thus more branched than that ofV. dilatatum.
