(Meliaceae) has been exploited due to the high quality of its wood and seeds. Particularly, the latter is a source of a medicinal oil of high value to the pharmaceutical industry. The indiscriminate use of this species has reduced its population size; therefore, scientific knowledge of its sexual propagation in nurseries is vital. This research aimed to evaluate seed germination of <em>C. guianensis</em> under different pre-germination treatments and substrates at the Centro de Investigación El Mira of AGROSAVIA. Pre-germination assays were conducted in a split-plot design with a random distribution of four repetitions. The cumulative germination percentage (CGP) and mean germination time (<em>t<sub>50</sub></em>) were calculated and analyzed through an ANOVA, and Tukey’s multiple comparison test using InfoStat V.2016. Significant differences for CGP among treatments (<em>p</em><0.0001) and interactions (<em>p</em><0.0096) were found. The highest germination percentage (61%) was achieved in S1+T4; however, the <em>T<sub>50 </sub></em>did not show significant differences (<em>p</em>=0.24). This research demonstrates that the highest germination percentage is achieved through a scarification treatment with imbibition in sand substrate under the agroclimatic conditions of Tumaco.</p>}, number={2}, journal={Revista de Ciencias Agrícolas}, author={Bacca, Pedro Pablo and Zuluaga, Jhon Jairo and Pérez, José Ives and Palacio, Manfred Ricardo}, year={2020}, month={Dec.}, pages={56–66} }
