Fenologia do pau-rosa (Aniba duckei Kostermans), Lauraceae, em floresta primária na Amazônia Central

Abstract

The authors study the phenology (flowering, fruiting and leaf changing) of a natural population of Pau-rosa (Aniba duckei Kostermans), Lauraceae, in a tropical rain forest near Manaus. The species behaviour and its relation with other species of this same area was observed. This species presents annual leaf changing, but this annual phenomenon does not occur in flowering and fruiting. When present, flowering has always occured during the wet season. Because of the flowering irregularity, and the great fruit predation by Psitacideae birds observed by the authors, the regular seed supply becomes difficult and for this reason research concerning new methods of vegetative propagation of this species is required.
