نبذة مختصرة : The seeds of Juglans neotropica Diels, having a very resistant testa to adverse conditions, interfere with germination at the nursery level, so there is a low production of plants in this species, which is important in different aspects: social, cultural, medicinal, among others. For this reason, it is necessary to determine the effect of pre-germination treatments of chemical origin and enrichment of substrates on the germination of J. neotropica Diels seeds from the San Blas parish, Urcuquí canton, Imbabura province. The research was carried out at the Yuyucocha Campus of the Técnica del Norte University, where both the seed quality and germination tests were carried out based on the provisions of the ISTA standards. The treatments used were chemical scarification with soaking in sodium hydroxide solutions, as well as enrichment of the substrate with cytokinins. The J. neotropica seed presented a 10% moisture content, while the percentage of purity was 97.66%; with an average weight per seed of 16.6 g; that in a kilogram it will carry 60 seeds. Regarding the effect of the interaction of pre-germination treatments of chemical origin and substrate enrichment on the germination of J. neotropica, it was evidenced that the best treatment was the one that had chemical scarification for 32 hours in a solution of hydroxide. 4% sodium, with the application of substrate enrichment with cytokinins. ; Las semillas de Juglans neotropica Diels al poseer una testa muy resistente a las condiciones adversas, producen una interferencia en la germinación a nivel de vivero, por lo que existe una baja producción de plantas en dicha especie, la cual posee una importancia en los aspectos sociales, culturales, medicinales, entre otros. Por tal motivo, es necesario determinar el efecto de tratamientos pregerminativos de origen químico y enriquecimiento de sustratos en la germinación de semillas de J. neotropica Diels provenientes de la parroquia San Blas, cantón Urcuquí, provincia de Imbabura. En la investigación se realizó en el ...
