A trial was carried out in Campinas, Brazil, from August 2005 to August 2006, in order to analyze the effect of two propagation methods (seeds and cuttings) on the development of Pfaffia glomerata (Spreng.) Pedersen. The experimental design was a completely randomized block, with five replications, and two methods of plant propagation. Plant height, aerial part dry mass and root dry mass were evaluated. Plants propagated from cuttings showed greater accumulation of dry mass on the aerial part. Root dry mass accumulation curves showed an exponential pattern, and at the end of the experimental period, the average of roots dry mass for both treatments were similar, up to 349,65 g plant-1. Neste trabalho, realizado no Instituto Agronômico, em Campinas-SP, de agosto/05 a agosto/06, estudou-se a influência de dois tipos de propagação no desenvolvimento de Pfaffia glomerata (Spreng.) Pedersen. O delineamento experimental utilizado foi inteiramente casualizado com cinco repetições, sendo nos tratamentos, estudadas duas formas de propagação da planta (semente e estacas). Foi avaliada a altura da planta, massa seca da parte aérea e massa seca da raiz. As plantas propagadas por estaca apresentaram maior acúmulo de massa seca da parte aérea comparativamente àquelas propagadas por sementes. As curvas de acúmulo de massa seca da raiz apresentaram comportamento exponencial, sendo que, ao final do período experimental, a produção de raízes foi semelhante para os dois tratamentos estudados, atingindo valores de até 349,65 g planta-1 de massa seca da raiz
