The objective of this study was to evaluate sexual and asexual propagation of Pfaffia glomerata (Brazilian Ginseng). The seeds were pre-soaked for 24 hours in KNO3 1% , gibberellic acid 50, 100, 200 mg L-1 , and in water. Untreated seeds served as control. Sowing was accomplished in petri dishes on 2 sheets of filter paper, at 25ºC incubation, under constant illumination, and in the absence of light. The cuttings with º1,5 cm were immersed for 6 hours in IAA 250 and 500mg L-1, boric acid1% ,and in water. Soon after they were planted in plastic containers with soil + sand (1:1). The first experiment was in factorial design 2 (light levels) x 6 (pre-soak treatment) in 4 repetitions of 20 seeds per repetition. The second in ERD in 5 treatments, 4 repetitions of 15 cuttings per repetition. Brazilian Ginseng seeds need pre-soak treatment to accelerate germination. We found immersion in KNO3 the most efficient method, providing 63% germination. They presented neuter photoblastism with an average germination of 45%. The Brazilian Ginseng cuttings immersed in water presented 100% rooting, a higher number of sprouts (2,5), and greater length (8,6 cm). The species presents potential for both propagation methods.
