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.
