Contextualization: Vochysia lehmannii is a native forest species of ecological importance in the eastern savannas of Colombia, used for ornamental, timber, food, and medicinal purposes. Knowledge gap: Its population and distribution are in progressive decline; however, it is not included in reforestation programs due to the lack of scientific knowledge about its germination, particularly about the synchrony of germination and environmental factors that influence it. Purpose: In this work, pre-germinative treatments with elements from the region are evaluated to identify which achieves the highest percentage of germination in a synchronous manner. Methodology: An experimental design with two factors: substrate and pre-germination treatments were established in the rural zone La Peral, Municipality of Paz de Ariporo, Casanare, Colombia. Black soil and river sand were used as substrates, and sanding, cutting and immersion in hot water were used as pre-germinative treatments. Results and conclusions: The treatment that obtained the highest germination percentage and the shortest dormancy time was the fertilized soil with seed cut, having a result of 80 % and 7 days respectively, with significant differences (P < 0.01) from the other treatments; however, asynchrony in germination persists., Contextualización: Vochysia lehmannii es una especie forestal nativa y de importancia ecológica en las sabanas orientales de Colombia, es utilizada con fines de ornamentación, madera, sus semillas tienen usos alimenticios y medicinales. Vacío de conocimiento: principalmente crece de manera silvestre debido a la falta de conocimiento científico sobre su germinación, particularmente acerca de la sincronía y factores ambientales que la influyen. Propósito: en este trabajo se evalúan tratamientos disponibles en la región para identificar el que logre mayor porcentaje de germinación de forma sincrónica. Metodología: En la Vereda La Peral del Municipio de Paz de Ariporo, Casanare, Colombia se estableció un diseño experimental con dos factores: sustrato y tratamientos pregerminativos. Como sustratos se utilizó tierra abonada y arena de río, y como tratamientos pregerminativos: lijado, corte e inmersión en agua caliente. Resultados y conclusiones: se obtuvo el mayor porcentaje de germinación y menor tiempo de latencia de 80% y 7 respectivamente como utilizando tierra abonada y corte de la semilla con diferencias significativas (P<0,01) de los demás tratamientos, sin embargo, persiste asincronía en la germinación.

The Vochysiaceae are represented in Peru by four genera and 32 species (Brako & Zarucchi, 1993; Ulloa Ulloa et al., 2004), all trees. Here we recognize two endemic species in the genus Qualea. These species are found in Humid Lowland Amazonian Forests region, between 100 and 160 m elevation. None of the endemic species have been recorded within Peru's protected areas system., La familia Vochysiaceae es reconocida en el Perú por presentar cuatro géneros y 32 especies (Brako & Zarucchi, 1993; Ulloa Ulloa et al., 2004), todas árboles. En este trabajo reconocemos dos especies endémicas en el género Qualea. Estas especies endémicas han sido encontradas en la región Bosques Húmedos Amazónicos, entre los 100 y 160 m de altitud. Ninguna especie endémica se encuentra representada dentro del Sistema Nacional de Áreas Naturales Protegidas por el Estado.
